Product representation

1. Detailed product information

Design: Graider gearbox has a compact and reasonable design. The box usually casts from high -strength alloy steel. It has good rigidity and impact resistance and can withstand high grader loads in difficult working conditions. The internal gear gear has passed accurate machining and heat treatment, has high accuracy of the teeth profile and the corresponding surface hardness, which ensures smoothness and reliability of the transmission. At the same time, the use of multi -disc clutch and brake provides quick, smooth and accurate gear shift.

The range of transmission transfer numbers is equipped with several different transmission transfer numbers to satisfy Grauder's needs in various working scenarios. For example, when leveling the soil, you can choose the appropriate transmission ratio to maintain a stable working speed of the grader; When towing heavy cargoes or lifting to the slopes, you can switch to a low gear ratio of the transmission in order to provide a greater torque. The range of transmission transfer numbers usually covers various working conditions: from low speed and high torque to high speed and low torque, in order to satisfy the needs for power under various operating conditions.

Transfiguration method: common transfers of transfers of gears include manual gear shift and gear shift under load. Manual gear shift directly controls the gearbox through the joystick. The operation is simple and straight, suitable for drivers with a high level of control skills. Power Shift uses a hydraulic control system that controls the clutch and brakes through electromagnetic valves to achieve automatic switching. The operation is more convenient and fast, which can effectively reduce the driver’s labor intensity and increase the efficiency of work.

Lubrication and cooling system: a forced lubrication and cooling system is used to guarantee that all the parts inside the gearbox are completely lubricated and cooled during operation. Lubric oil circulates through the oil pump, removing the heat released by gears, bearings and other components during operation, and forming an oil film on each surface of the friction, which reduces wear. The cooling system usually uses air or water cooling, which is selected depending on various working conditions and requirements to guarantee the operation of the gearbox in the corresponding temperature range.

The efficiency of the seal: the gearbox has good characteristics of the seal and uses high -quality seals, such as oil seals, sealing rings, etc., which effectively prevent leakage of lubricating oil and entering the gearbox of external pollution, such as dust and moisture, ensuring the normal operation and service life of the gearbox.

2. The installation method

Preparation before installation: before installing the grader gearbox, the installation site must be cleaned and inspected to make sure that the installation surface is even and free from garbage. At the same time, prepare the necessary installation tools and accessories, such as bolts, gaskets, etc.

Rise and positioning: Use the appropriate lifting equipment to smoothly raise the gearbox to the installation site and accurately place it in accordance with the relative location of the gearbox and engine, drive shaft and other components. Make sure that the input shaft of the gearbox is concentrated, the output shaft of the engine and that the connection between the output shaft and the drive shaft is accurate.

Fastening and connection: Use the indicated bolts and washers for reliable fixation of the gearbox at the installation site and tighten the bolts in accordance with the indicated requirements for the torque to guarantee that the gearbox does not weaken during operation. At the same time, connect the lubricant of the gear lubricant, the cooling pipeline, the control pipeline, etc., to verify the reliability of the connection and a good sealed connection.

Adjustment and check: After installation, the gearbox must be completely adjusted and checked. Check the flexibility and accuracy of the gear shift mechanism, the correspondence of the lubricating oil level to the specified range, the serviceability of the cooling system, etc. If necessary, perform the appropriate adjustments and repairs to ensure the correct and reliable installation of the gearbox.

3. Repair and maintenance

Daily service: regularly check the level of lubricant oil in the gearbox to make sure that it is in the specified range. Check the quality of lubricating oil. If it is found that the lubricant has deteriorated, emulsized or impurities, it should be replaced in time. At the same time, check if there are leaks in the sealing part of the gearbox. If there are leaks, they should be eliminated on time.

Regularly replace the lubricating oil: regularly replace the lubricant in accordance with the instructions for the operation of the gearbox and operating conditions. As a rule, under normal operating conditions, lubricants should be replaced every 500-1000 working hours or every six months. In difficult working conditions, such as high temperature, high dustiness, high humidity, etc., the replacement cycle should be reduced accordingly.

Filter replacement: regularly replace the oil transmission oil filter to ensure the purity of lubricant oil. The filter replacement cycle is usually the same as the lubricating oil replacement cycle. When replacing the filter, pay attention to the direction of the installation and the tightness of the filter to make sure that the filter is installed.

Checking and maintenance of the components: regularly check the working condition of the gearbox, clutch, brake and other gearbox components. If any parts are worn out, weakened or damaged, they should be repaired or replaced in time. Check if the transmission cooling system correctly works, for example, whether the radiator is clogged, whether the fan works, etc. If there are any problems, they should be eliminated on time.

Elimination of malfunctions: in case of malfunctions in the operation of the gearbox, the car should be stopped in a timely manner, to analyze the cause of the malfunction and take appropriate measures to eliminate it. In case of elimination of malfunctions, it is necessary to strictly comply with the requirements of the maintenance management manual in order to avoid expanding the malfunction or damage to other components due to improper operation.

4. Common malfunctions

There are many types of malfunctions that may occur in the gearbox of the grader during use. Below are some common types of malfunctions and their causes:

The complexity of the gear shift:

The malfunction of the transfers mechanism: for example, the gearbox fork is worn out, deformed or stuck, which leads to the impossibility of normal gear shifts.

Clutch problem: the clutch is not completely disconnected, so it is impossible to completely turn off the power, which is why the gears are difficult to turn on when switching gears, which leads to a knock of gears that make it difficult to switch.

The problem with lubricating oil: the lubricant oil is too dirty or has too high viscosity, which affects the lubricant and movement between the switching parts and increases the resistance to switching.

The malfunction of the electromagnetic gearbox valve (for transmissions with transfers of gears under load): if the electromagnetic valve fails, it cannot accurately control the flow and pressure of hydraulic oil, which, in turn, affects the clutch and brake, which leads to difficulty gearing.

Abnormal sound:

Histers wear: after prolonged use, the surface of the gears wears out, covered with potholes, peeling, etc., which leads to the appearance of unusual hooking sounds during operation.

Bearing damage: carrier wear, cracks on balls or damage to the separator can lead to poor operation of the bearing and noise.

Insufficient amount or worsening of the quality of lubricating oil: insufficient amount of lubricating oil or deterioration of its quality will lead to the fact that it cannot effectively lubricate and soften friction between the components, which will lead to abnormal noise.

Weakened internal components: if components such as shutter shafts and bolts are weakened, vibrations can lead to knocks during operation.

Oil leak:

Acting or damage to seals: after prolonged use, oil seals, sealing rings and other seals of the gearbox are aging, hard or break, which leads to a leakage of lubricating oil.

An uneven sealing surface: the sealing surfaces of the case, shaft neck and other parts have defects obtained during the manufacture or installation, or deformed due to a long load, which leads to a deterioration in the seal and leakage of the oil.

A clogged ventilation hole: a clogged ventilation hole leads to an increase in the internal pressure in the transmission, which leads to seeping lubricant over a weak seal.

The oil temperature is too high:

Cooling malfunction: clogging of the radiator, fan failure, or clogging of cooling lines worsen the excretion of heat and lead to an increase in oil temperature.

Insufficient or spoiled lubricants: insufficient amount of lubricating oil will increase friction between the components and release more heat; While spoiled lubricants will reduce heat scattering and lubricants, which will also lead to an increase in oil temperature.

Long -term work with high load: when a grader works in high load conditions for a long time, loss of power inside the gearbox increases, which leads to the formation of excess heat and an increase in oil temperature.

Poor gear engagement: improper gear clutch, poor contact of the surfaces of the teeth, etc. Increase friction and wear between gears, generate additional heat and increase oil temperature.

Jumping equipment:

Distribution of the gearbox fork: strong wear of the gearbox fork will lead to inaccurate positioning of the gears, and the gears will easily automatically leave the engagement during operation, which will lead to jumping of the gears.

The malfunction of the self -locking device: a self -locking device of the gearbox (for example, a self -locking spring, steel ball, etc.) fails and cannot reliably fix the position of the gear, which leads to easily jumping on the gear from the transmission during operation.

Val deformation: the shaft of the gearbox is deformed under the influence of prolonged power, which violates the normal engagement of gears and leads to the transfer of gears.

A break in the supply of electricity:

Clutch malfunction: severe wear of the clutch friction disk, erosion during fire or refusal of a hydraulic adhesion system will lead to the fact that the clutch will not be able to normally transmit power, which will lead to an interruption of power transmission.

The internal breakdown of the gear or shaft: in the case of a strong overload or blow, the gear or shaft may break, which will make normal power transmission impossible.
