Description

Technical Field

[0001] This utility model relates to the field of speed reducer protection, specifically a speed reducer oil leakage protection structure. Background Technology

[0002] The "oil-proof reducer structure" disclosed in publication number "CN221683538U" is also an increasingly mature technology. Its "invention" reduces the internal and external pressure difference, thus preventing oil from seeping out of the reducer's gaps due to excessive internal pressure. Furthermore, due to the special shape of the special air supply pipe, when oil splashes into the pipe, the inclined plane inside will cause the oil splashed by the high-speed rotating oil slinger to slide down into the reducer, thus allowing the internal pressure of the reducer to be discharged through the special air supply pipe. This limits oil leakage from the reducer. However, the reducer still has the following drawbacks during use: While the air supply pipe and inclined plane structure do prevent oil leakage, these structures do not facilitate the guidance of leaking oil, which remains inside the reducer and affects the protection effect. Therefore, it is necessary to provide a protective structure that can easily guide and discharge leaking oil, thus improving the protection effect. In addition, the existing reducer is inconvenient to disassemble its components. Therefore, it is necessary to provide a protective structure that facilitates disassembly and improves the ease of disassembly. Utility Model Content

[0006] As a preferred embodiment of this utility model, a mounting plate is installed at the rear end of the reducer housing.

[0007] As a preferred embodiment of this utility model, the mounting plate and the reducer housing are both internally threaded with a number of bolts, and the rear ends of the mounting plate and the reducer housing are both provided with a number of screw holes, and the number of bolts are all threaded into the inside of the screw holes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 This utility model provides a gear reducer oil leakage protection structure, including a protection component 100;

[0023] The protection component 100 includes a reducer housing 101, an outlet 102 on the reducer housing 101, an oil seal 103 installed inside the reducer housing 101, an overflow groove 104 on the inner wall of the reducer housing 101, a bearing 105 installed at the front end of the reducer housing 101, a sensor 106 installed on one side of the reducer housing 101, a positioning ring 107 fixedly installed at the front end of the reducer housing 101, the bearing 105 installed inside the positioning ring 107, a rotating shaft 108 rotatably connected inside the bearing 105, a first gasket 109 and a second gasket 110 respectively installed on both sides of the bearing 105, and a filter 120 installed inside the outlet 102.

[0024] In one specific embodiment, the protective component 100 not only improves the oil leakage protection effect of the reducer but also drains the oil, thereby enhancing the protective performance of the protective structure. Furthermore, the interplay of these structures facilitates the disassembly of each component, improving the ease of disassembly and replacement. In use, the motor shaft 108 in the reducer oil leakage protection structure passes through a shaft hole and is fixed by a bearing 105. An oil seal 103 is fitted onto the axial side surface of the bearing 105 on the shaft 108. An overflow outlet is provided between the bearing 105 and the oil seal 103 in the reducer oil leakage protection structure. The system includes a trough 104 and an outlet 102. A filter 120 and a sensor 106 are provided on the outer end face of the outlet 102. When the oil seal 103 leaks, the oil is led to the outlet 102 through the overflow trough 104 and filtered out of the reducer by the filter 120. At the same time, the sensor 106 detects the leak and issues an alarm. The reducer oil leakage protection structure can prevent the leaked material from damaging the reducer when the reducer oil seal 103 leaks. Subsequently, the oil leakage of the reducer can be checked through the outlet 102, which facilitates the maintenance of the reducer and enhances the protective effect of the protection structure.

[0025] Please see Figures 2-6 A mounting plate 111 is installed at the rear end of the reducer housing 101.

[0026] In one specific embodiment, the mounting plate 111 can seal the reducer housing 101, thereby improving the overall structural stability of the reducer.

[0027] Please see Figures 2-6 The mounting plate 111 and the reducer housing 101 are both threaded with several bolts 121. The rear ends of the mounting plate 111 and the reducer housing 101 are both provided with several screw holes 122, and the bolts 121 are threaded into the screw holes 122.

[0028] In one specific embodiment, the bolt 121 is threaded inside the bolt hole 122, which enhances the installation strength between the mounting plate 111 and the reducer housing 101. After the bolt 121 is removed, the various components of the reducer can be disassembled.

[0029] Please see Figures 2-6 One end of the sensor 106 is fixedly connected to a connector 131, which is threaded into the inside of the overflow groove 104. The inner wall of the positioning ring 107 has an annular groove 132, and the first gasket 109 is installed inside the annular groove 132.

[0030] In one specific embodiment, the connector 131 facilitates the threaded connection between the sensor 106 and the reducer housing 101, and the annular groove 132 facilitates the installation and positioning of the first gasket 109, thereby improving the ease of installation and removal of the first gasket 109.

[0031] Please see Figures 2-6 The reducer housing 101 and the mounting plate 111 are both made of cast aluminum.

[0032] In one specific embodiment, the gearbox housing 101 and mounting plate 111, made of cast aluminum, can reduce the weight, thereby improving the ease of carrying and using the gearbox.

[0033] Please see Figures 2-6 The pivot 108 is made of stainless steel.

[0034] In one specific embodiment, the stainless steel shaft 108 can avoid damage and extend its service life.

[0035] Working principle: In use, the motor shaft 108 in the reducer oil leakage protection structure passes through the shaft hole and is fixed by the bearing 105. The bearing 105 has an oil seal 103 sleeved on the axial side surface of the shaft 108. The reducer oil leakage protection structure has an overflow groove 104 and an outlet 102 between the bearing 105 and the oil seal 103. A filter 120 and a sensor 106 are provided on the outer end face of the outlet 102. When the oil seal 103 leaks, the oil is led to the outlet 102 through the overflow groove 104 and filtered out of the reducer through the filter 120. The sensor 106 detects the leak and issues an alarm. In addition, the reducer oil leakage protection structure can prevent the leaked material from damaging the reducer when the reducer oil seal 103 leaks. Finally, the oil leakage of the reducer can be checked through the outlet 102, which can facilitate the maintenance of the reducer. Therefore, the protection effect of the protection structure can be enhanced.
