Description

TECHNICAL FIELD

[0001] The utility model relates to bearing seat sealing technical field, concretely relates to a speed reducer bearing chamber sealing through cover. BACKGROUND

[0002] The high speed shaft of the speed reducer is connected with the power machine and is the power input shaft, and the low speed shaft is connected with the execution machine and is the power output shaft. The input shaft and the output shaft of the speed reducer are provided with lubricating oil, and the sealing through cover is installed outside the bearing chamber to prevent the lubricating oil from leaking to the shaft end. The sealing through cover is designed with a sealing structure at the dynamic and static combination part of the rotating shaft.

[0003] The existing sealing structure of the bearing chamber of the speed reducer mostly adopts a multi-stage sealing structure, such as a simple sealing form of felt or skeleton shaft seal. The leakage of lubricating oil is delayed by stacking multiple sealing structures. However, during the use of the speed reducer, if the operation is improper, the environment is harsh, and the speed reducer is subjected to impact during operation, the sealing structures will wear out, accelerate the aging of the rubber material, and cause damage to the material of the sealing structure, resulting in leakage of lubricating oil. Therefore, we propose a sealing through cover for the bearing chamber of the speed reducer. SUMMARY

[0004] In view of the problems in the prior art, the utility model provides a sealing through cover for the bearing chamber of the speed reducer.

[0005] The utility model solves the technical problems by adopting the technical scheme of a sealing through cover for the bearing chamber of the speed reducer, which includes a mounting base. The side wall of the mounting base is fixedly connected with multiple limiting rods. The limiting rods are inserted into the side wall sliding grooves of a dynamic ring base. The mounting base is clamped with the dynamic ring base through the limiting rods. The inside of the side of the dynamic ring base away from the mounting base is slidingly connected with an adapter ring. The end of the adapter ring away from the dynamic ring base is fixedly connected with a connecting rod.

[0006] The inside of the dynamic ring base is provided with a sliding groove. The inside of the sliding groove is fixedly connected with an elastic return member. The end of the elastic return member away from the sliding groove is fixedly connected with a buffer washer. The side surface of the adapter ring is provided with a matching groove matching the buffer washer. The adapter ring is slidingly located in the cavity inside the dynamic ring base through the buffer washer.

[0007] By adopting the technical scheme, the multiple blocking mechanisms are formed in the using process through the traditional sealing connection structure layer by layer, so as to intercept the lubricating oil leakage, thereby ensuring that the internal lubricating oil does not leak due to normal use within as long as possible using time, and the damage of the equipment and the environmental pollution are avoided, and the sliding buffer mechanism between the dynamic ring base and the adapter ring is used to avoid the shaking of the sealing cover in the using process under the condition that the reducer is impacted or the using environment is harsh, so as to avoid the friction of the internal sealing structure caused by the shaking, and the material of the sealing structure is damaged, and the effective service life of the equipment is relatively improved.

[0008] Specifically, the outer periphery of the connecting rod is fixedly connected with a limiting ring, and the outer periphery of the connecting rod is slidably connected with a static ring, and the sliding range of the static ring is limited by the limiting ring.

[0009] By adopting the technical scheme, the dynamic ring base is limited by the limiting ring, so that the dynamic ring base can only rotate with the mounting base mounted on the outer periphery of the output shaft of the reducer and cannot rotate freely.

[0010] Specifically, an elastic compensation ring is assembled between the mounting base and the plurality of limiting rods, and one end of the elastic compensation ring away from the mounting base abuts against the inside of the dynamic ring base through an elastic sealing washer.

[0011] By adopting the technical scheme, the elastic compensation ring is arranged between the mounting base and the dynamic ring base, so as to support the dynamic ring base in cooperation with the limiting rods during the pressure displacement of the dynamic ring base caused by the sliding of the adapter ring.

[0012] Specifically, a buffer sealing washer for buffering is assembled between the static ring and the limiting ring.

[0013] By adopting the technical scheme, the impact force generated by the sliding buffer structure is reduced through the buffer sealing washer, so as to improve the service life of the equipment.

[0014] Specifically, the mounting base and the connecting structure are both sleeved on the outer periphery of the output shaft of the reducer, and one end of the static ring away from the adapter ring abuts against the inner wall of the output port of the reducer.

[0015] By adopting the technical scheme, the output port of the bearing chamber of the reducer is sealed by mounting the mounting base on the outer periphery of the output shaft and abutting the static ring against the inner wall of the output port.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The technical scheme of the application forms multiple blocking mechanisms in the using process through the traditional sealing connection structure layer by layer, so as to intercept the lubricating oil leakage, thereby ensuring that the internal lubricating oil does not leak due to normal use to cause the equipment damage and environmental pollution within as long as possible using time.

[0018] The sliding buffer mechanism between the dynamic ring base and the adapter ring is used to avoid the shaking of the sealing cover in the using process, so as to avoid the friction of the internal sealing structure caused by the shaking of the sealing cover in the case that the speed reducer is impacted or the using environment is bad, the material of the sealing structure is damaged, and the effective life of the equipment is relatively improved.
