S1800-2 Vogele paver scraper reducer

Speed reducer, reducer, reducer, important things say three times. Here we solemnly introduce the construction machinery home brought reducer.

1. What's the function of the reducer?

Adding a reducer can reduce the moment of inertia, generally the square of the speed ratio decreases, which is very important for the control, can timely control start stop, speed change. Increasing torque through the reducer is equivalent to increasing the input power, can reduce the power required for the input motor (in the case of speed regulation), in general, the motor is more expensive than the reducer, so consider the use of reducer.

2, the use of the process often encountered problems, how to use properly

Due to non-standard use habits, often the reducer oil leakage situation. So in the usual use of the process should pay attention to:

(1) maintain the balance of the pressure difference is generated inside and outside gear reducer: during operation, frictional heating and the influence of environmental temperature, the speed reducer temperature, if there is no air holes or air holes inside the machine is blocked, the pressure gradually increased, the internal temperature is higher, and the external pressure difference increasing lubrication oil under pressure, leakage from the gap.

(2) reducer structure design is not reasonable, including the manhole cover plate is too thin, tighten the bolts after deformation, the uneven surface, oil leakage from the contact gap;

During the manufacturing process of the reducer, the casting does not undergo annealing or aging treatment, and the internal stress is not eliminated. The deformation must occur and the gap will occur, leading to leakage;

There is no oil return tank on the box, the lubricating oil accumulates in the shaft seal, the end cover, the joint surface and so on. Under the action of pressure difference, the oil leaks out from the gap;

The structural design of shaft seal is unreasonable. In the early speed reducer, the oil groove and felt ring type shaft seal structure were adopted. When the assembly was made, the felt was compressed to produce deformation, and the joint surface gap was sealed. If the contact between the shaft neck and the seal is not ideal, the seal will fail in a short time due to poor compensation performance of the felt. Although there is oil return hole in oil groove, it is easy to block and oil recovery is difficult to play.

(3) control the amount of fuel: Reducer in the operation process, the oil pool is stirred very seriously, lubricating oil splashing everywhere in the machine, if the amount of fuel is too much, so that a large number of lubricating oil accumulation in the shaft seal, joint surface and so on, leading to leakage.

(4) the standard maintenance process: when the equipment is repaired, because the dirt on the joint surface is not completely cleaned, or the improper selection of sealant, the direction of sealing installation and the timely replacement of seals will also cause oil leakage.
