Description

Speed reducer gasket

Technical Field

The utility model relates to a reduction gear gasket technical field, in particular to reduction gear gasket.

Background

Retarder washers are used as gaskets between retarder nuts during vehicle operation, typically to protect against pressure, corrosion between two objects, and a leak (typically in the middle) that is a thin (typically circular) plate is typically a load thread fastener for distribution. The other use is as a spacer.

However, when the existing speed reducer gasket slides, the gasket also slides along with the sliding of the speed reducer, so that the speed reducer is loosened for a long time, and the service life is short due to the fact that no abrasion occurs between the speed reducer and the gasket.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, the utility model aims to: the problem of current reduction gear gasket when the reduction gear slides, the gasket also slides thereupon, and then produces between the reduction gear not hard up, the time is longer, appears not wearing and tearing between, leads to the life-span shorter is solved.

The technical scheme includes that the speed reducer gasket comprises a gasket body, wherein two flanges are arranged on the end face of the gasket body, the end face of the gasket body is located at two positions, a clamping groove is formed between the flanges, a plurality of inner grooves are formed in the gasket body all around, and threaded grooves are formed in the upper side and the lower side of each inner groove.

Furthermore, the end face of the gasket body is located on the outer side of the clamping groove, and two limiting grooves are formed in the limiting groove and located at the upper end and the lower end of the gasket body respectively.

Furthermore, a plurality of limiting holes are formed in the periphery of the end face of the gasket body.

Furthermore, the inside of gasket body is fixedly connected with locating piece all around, the locating piece is provided with four.

To sum up the utility model discloses following technological effect has: this kind of reduction gear gasket is provided with the screens groove through the terminal surface at the gasket body, mutually supports between the nut of screens groove and reduction gear, and then can not produce between the slip to at four locating pieces of inside fixedly connected with of gasket body, carry out the screens through four locating pieces, and then can not produce relative slip, reduced wearing and tearing between, and then increased the life-span.

Detailed Description

The first embodiment is as follows:

as shown in fig. 1-4, a gasket for a speed reducer comprises a gasket body 1, two flanges 21 are arranged on an end surface of the gasket body 1, and a clamping groove 2 is formed on the end surface of the gasket body 1 and between the two flanges 21.

The terminal surface of gasket body 1 just is located the outside in screens groove 2 and has seted up spacing groove 3, and spacing groove 3 has seted up two, is located the upper and lower end of gasket body 1 respectively, and a plurality of spacing holes 4 have been seted up all around to the terminal surface of gasket body 1.

In the present embodiment, two strip flanges 21 are fixedly attached to the upper side of the gasket body 1. The clamping groove 2 formed between the two flanges 21 is matched with the nut of the speed reducer, so that the gasket is matched with the speed reducer, and the gasket cannot slide.

Wherein, spacing groove 3 is provided with two, and two spacing grooves 3 are located the upper and lower both sides of gasket body 1 respectively, and spacing hole 4 sets up around 1 terminal surface of gasket body, and then has increased the frictional force between the nut of gasket and reduction gear through spacing groove 3 and spacing hole 4.

Example two:

as shown in fig. 1 to 4, a gasket for a speed reducer comprises a gasket body 1, wherein two flanges 21 are arranged on the end surface of the gasket body 1, a clamping groove 2 is formed between the two flanges 21 on the end surface of the gasket body 1, a plurality of inner grooves 5 are formed around the inside of the gasket body 1, and thread grooves 6 are formed in the inside of the gasket body 1 and on the upper and lower sides of the inner grooves 5.

The difference between this embodiment and embodiment one lies in, a plurality of inner groves 5 have been seted up all around to the inside of gasket body 1, and threaded groove 6 has been seted up to the inside of gasket body 1 and the upper and lower both sides that are located inner grove 5, has increased the frictional force between the nut of inside and the reduction gear of gasket through inner grove 5 to the fixity between the two has been increased through threaded groove 6, and then has increased stable effect.

Example three:

combining the first embodiment and the second embodiment, a speed reducer gasket comprises a gasket body 1, wherein two flanges 21 are arranged on the end surface of the gasket body 1, a clamping groove 2 is formed between the two flanges 21 on the end surface of the gasket body 1, a plurality of inner grooves 5 are formed around the inside of the gasket body 1, and thread grooves 6 are formed in the inside of the gasket body 1 and on the upper side and the lower side of the inner grooves 5.

The inside of gasket body 1 is fixedly connected with locating piece 7 all around, and locating piece 7 is provided with four.

The difference between the first embodiment and the second embodiment is that four positioning blocks 7 are arranged around the inside of the gasket body 1, and the friction force between the inside of the gasket and the nut of the speed reducer is added through the four positioning blocks 7, so that the stability is synchronously improved.

To sum up, through being provided with screens groove 2 at gasket body 1's terminal surface, mutually support between screens groove 2 and the nut of reduction gear, and then can not produce the slip between them to at four locating pieces 7 of gasket body 1's inside fixedly connected with, carry out the screens through four locating pieces 7, and then can not produce relative slip, reduced wearing and tearing between, and then increased the life-span.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
