What are the common faults and solutions of TY125-38-7.5KW reducer

TY125-38-7.5KW reducer is a common mechanical equipment. The following are its common faults and solutions:

Gearbox overheating and high oil temperature

Reason for malfunction: Excessive load, exceeding the bearing capacity of the gearbox; Improper installation position of reducer, poor ventilation and heat dissipation conditions; Improper selection of lubricating oil or high or low oil level; The gears are severely worn and generate excessive heat.

Solution: Reasonably adjust the load to avoid overloading operation; Re select the installation location to ensure sufficient space around the gearbox for ventilation and heat dissipation; Choose appropriate lubricating oil, regularly check the oil level to ensure that the oil level is normal; Check the wear of the gears, and if the wear is severe, replace the gears in a timely manner.

Excessive vibration of the gearbox

Reason for malfunction: Insufficient installation accuracy between the reducer and the motor or other equipment, resulting in misalignment of the axis; Gear wear or damage, causing poor meshing; Loose anchor bolts result in unstable fixation of the gearbox; Uneven load generates impact load.

Solution: Adjust the installation accuracy again to ensure that the axis of the reducer coincides with the relevant equipment; Check the condition of the gears and replace worn or damaged gears; Tighten the anchor bolts to ensure the gearbox is securely installed; Optimize load distribution to avoid impact loads.

Abnormal noise of gearbox

Reason for malfunction: Poor gear meshing, such as tooth surface wear, tooth profile errors, etc; Bearing damage leads to unstable rotation; Insufficient or deteriorated lubricating oil affects the lubrication effect; Foreign objects have entered the interior of the gearbox.

Solution: Check the gear meshing condition, repair or replace the gear; Replace damaged bearings; Regularly inspect and replace lubricating oil to ensure sufficient lubricating oil supply; Clean up foreign objects inside the gearbox.

Gearbox oil leakage

Reason for malfunction: Aging and damage of the sealing components, resulting in oil leakage; The oil level is too high, causing the oil to overflow from the vent hole or other gaps; The gearbox body is cracked or has sand holes, causing oil leakage.

Solution: Replace aging or damaged seals; Adjust the oil level to the normal height; Repair or replace the broken or sand holes in the box.

Abnormal output shaft speed of reducer

Reason for malfunction: Motor malfunction, such as short circuit or open circuit in the motor winding; The internal gear transmission mechanism of the reducer is damaged, such as gear tooth breakage, shaft breakage, etc; The coupling is damaged, resulting in poor power transmission.

Solution: Check the motor, repair or replace it; Disassemble the gearbox, inspect the internal gear transmission mechanism, and replace damaged components; Check the coupling, repair or replace it.

Reduced transmission efficiency of gearbox

Fault cause: Gear wear, increased tooth surface roughness, resulting in increased transmission friction force; Bearing damage increases rotational resistance; The performance of lubricating oil decreases, and the lubrication effect deteriorates.
