AI Technical Summary

Technical Problem

Traditional spherical gaskets have a thin wear-resistant layer and a short service life, resulting in severe wear between the reducer housing and the gasket, which affects transmission efficiency and lifespan.

Method used

The self-adaptive spherical gasket is made of high-lead-tin bronze material. The gasket has a circular hole in the center and grooves for storing lubricating oil on the concave surface. The outer side is made of composite steel plate. The grooves are symmetrically distributed along the diameter of the circular hole, and the circular hole has a smooth surface.

Benefits of technology

Using high-lead-tin bronze material with good ductility and strong self-lubrication, the gasket expands on the inner side to match the shape of the part when under pressure, disperses local pressure, increases the contact area, extends the life of the part and reduces wear.

Description

Technical Field

[0001] This utility model relates to the field of speed reducers, and in particular to an adaptive spherical gasket for run-in before speed reducer assembly. Background Technology

[0002] In speed reducers, wear between the reducer housing and the gaskets is one of the main causes of reducer assembly failure. Therefore, the contact area between the reducer housing and the gaskets needs to be adequately lubricated to reduce friction and wear, and improve transmission efficiency and lifespan.

[0003] Traditional spherical gaskets have a layer of PTFE (polytetrafluoroethylene) material on the inner spherical surface of the friction pair. However, the wear-resistant layer of PTFE is relatively thin and has a short service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adaptive spherical gasket for run-in before gearbox assembly, thereby solving the problem of short life of traditional spherical gaskets.

[0005] To solve the above-mentioned technical problems, this utility model provides an adaptive spherical gasket for run-in before assembling a reducer. The gasket is made of high-lead-tin bronze material, is spherical, has a circular hole in the center, and has grooves for storing lubricating oil on the inner concave surface of the gasket.

[0006] In the preferred embodiment, the high-lead tin bronze material is C93800.

[0007] In the preferred embodiment, a steel plate is laminated to the outside of the gasket, and the circular hole is located on the steel plate.

[0008] In a preferred embodiment, the grooves are symmetrically distributed around the circular hole and are distributed along the direction of the diameter of the circular hole.

[0009] In a preferred embodiment, one side of the groove is connected to a circular hole, and the depth of the groove is less than the thickness of the steel plate.

[0010] In the preferred embodiment, the circular hole has a smooth surface.

[0011] The beneficial effects of this utility model are as follows: Because this utility model sets up an adaptive spherical gasket for the run-in of the reducer before assembly, the gasket is made of tin bronze material. When subjected to pressure, the inner side of the gasket can extend, thereby better matching the shape of the part, so as to increase the overall contact area of ​​the part, achieve the effect of dispersing local pressure, and ultimately improve the service life of the part. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0013] Figure 1This is a partial sectional view of an embodiment of the present invention.

[0014] Figure 2 This is a side view of an embodiment of the present invention;

[0015] Figure 3 This is a partially enlarged structural diagram of the groove in an embodiment of this utility model.

[0016] Reference numerals: 11. Circular hole; 12. Groove; 13. Steel plate. Detailed Implementation

[0017] Please see Figure 1-3 As shown, this application provides a technical solution: an adaptive spherical gasket for run-in before assembling a reducer. The gasket is made of high-lead-tin bronze material, is spherical, has a circular hole 11 at its center, and has a groove 12 for storing lubricating oil on its inner concave surface.

[0018] In the preferred embodiment, the high-lead tin bronze material is C93800.

[0019] The bronze material, C93800, is a copper-based alloy containing tin and lead. It is self-lubricating, high-strength, and also possesses good toughness and ductility. Because the gasket has excellent ductility, its inner side can expand under pressure, thus better matching the shape of the part. This results in a larger overall contact area, effectively dispersing localized pressure and ultimately extending the part's lifespan.

[0020] In a preferred embodiment, a steel plate 13 is laminated on the outside of the gasket, and a circular hole 11 is provided on the steel plate 13.

[0021] Because steel plate 13 is less prone to deformation than copper, the round hole 11 is also less prone to deformation. The round hole 11 can match the shape of the part, thus playing a guiding role. Ideally, the deformed round hole will also facilitate the removal of the gasket.

[0022] In a preferred embodiment, the grooves 12 are symmetrically distributed around the circular hole 11 and are distributed along the direction of the diameter of the circular hole 11.

[0023] The symmetrical distribution of grooves 12 is conducive to uniform stress distribution.

[0024] In a preferred embodiment, one side of the groove 12 is connected to the circular hole 11, and the depth of the groove 12 is less than the thickness of the steel plate 13.

[0025] In this way, some of the lubricating oil can enter through the round hole 11 and eventually be stored in the groove 12.

[0026] In the preferred embodiment, the circular hole 11 has a smooth surface.

[0027] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
