Abstract

The invention discloses a dynamic sealing device and a wheel side speed reducer provided with the same. The disclosed dynamic sealing device is used for sealing a gap between a first object (2-1) and a second object (3-1) which relatively move, the dynamic sealing device comprises an elastic body (4) for filling the gap, and an elastic compensator (5) for supporting the elastic body (4) is also arranged between the first object (2-1) and the second object (3-1), so that the elastic body (4) can cling to the first object (2-1). The elastic compensator (5) provides supporting power for the elastic body (4), so that the worn elastic body (4) can still cling to the first object (2-1), and the sealing between the first object (2-1) and the second object (3-1) is kept, thereby prolonging the service life of the dynamic sealing device, reducing the total vehicle fault rate of the wheel side speed reducer, decreasing the maintenance frequency and improving the work efficiency of the wheel side speed reducer.

Description

Technical field [0001] The invention relates to the field of sealing, in particular to a dynamic sealing device. In addition, the present invention also relates to a wheel rim reducer with the above-mentioned dynamic sealing device. Background technique [0002] Dynamic sealing device is an important part of many construction machinery, and its sealing performance will directly affect the working performance of construction machinery. With the continuous progress of society, the requirements for the sealing performance of construction machinery are getting higher and higher. How to dynamically seal construction machinery efficiently and economically is an important issue that many engineers and technicians pay attention to. [0003] Taking the wheel reducer as an example, the dynamic sealing performance between the rotating part and the fixed part has a great influence on the working efficiency of the wheel reducer. [0004] Please refer to Figure 1 to Figure 3 , figure 1 It is a ...
