Description

High-strength eccentric bearing for three-ring speed reducer

Technical Field

The utility model relates to the technical field of eccentric bearings, in particular to an eccentric bearing with high strength for a three-ring speed reducer.

Background

An eccentric bearing, which is a very useful bearing type, is one of the important accessories of a three-ring reducer.

At present, eccentric bearing outer rings on the market are all self-contained limiting structures, and the rolling needles are installed through the outer rings, so that the disassembly convenience can be greatly reduced when the eccentric bearing outer rings are disassembled.

The existing high-strength eccentric bearing for the three-ring speed reducer also has the following disadvantages: 1. a limiting structure which avoids dislocation of the roller pins and is convenient to disassemble and assemble is lacked, so that the disassembling and assembling convenience is greatly reduced; 2. lack and be convenient for paint lubricating oil structure for the simple operation nature has reduced by a wide margin when needing to maintain it. For this reason, we propose an eccentric bearing for a three-ring speed reducer that is high in strength.

Disclosure of Invention

The utility model mainly aims to provide an eccentric bearing with high strength for a three-ring speed reducer, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the high-strength eccentric bearing for the three-ring speed reducer comprises an inner ring, an axis and an outer ring, wherein roller pins are uniformly filled between the inner ring and the outer ring, mounting holes are formed in the top and the bottom of the surfaces of two sides of the inner ring, and limiting rings are arranged on the surfaces of two sides of the inner ring.

Furthermore, an oil inlet is formed in one side of the peripheral surface of the outer ring, fixing holes are formed in the positions, corresponding to the mounting holes, of the surface of the limiting ring, and the limiting ring is fixed in the mounting holes through fixing holes and screws; the limiting ring is conveniently arranged in the mounting hole through the fixing hole.

Furthermore, the axle center is located the inner circle surface top, the axle center inner wall is glutinous to be equipped with the abrasionproof pad, the abrasionproof pad is rubber materials.

Furthermore, ball grooves are uniformly formed in the periphery of the inner side surface of the limiting ring around the center, and balls are filled in the ball grooves; the ball is matched with the roller pin to move.

Further, the outer ring is located on the periphery of the inner ring.

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

1. through setting up spacing collar, ball groove and ball, utilize the ball that the inboard surface ball inslot of spacing collar was established to fill in with the cooperation kingpin motion, during the dismantlement, dismantle the screw and get the spacing collar and lift off and can accomplish the dismantlement to the realization is avoided the kingpin dislocation and is convenient for the effect of dismouting, thereby has promoted the dismouting convenience by a wide margin.

2. Through setting up the oil inlet, utilize the oil inlet to pour into lubricating oil into in order to realize carrying out lubricated effect to the kingpin to the simple operation nature has been promoted by a wide margin.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-3, the high-strength eccentric bearing for the three-ring speed reducer comprises an inner ring 1, an axis 2 and an outer ring 4, wherein needle rollers 5 are uniformly filled between the inner ring 1 and the outer ring 4, mounting holes 7 are formed in the top and the bottom of the surfaces of two sides of the inner ring 1, and limiting rings 8 are arranged on the surfaces of two sides of the inner ring 1.

An oil inlet 6 is formed in one side of the peripheral surface of the outer ring 4, fixing holes 9 are formed in the positions, corresponding to the mounting holes 7, of the surface of the limiting ring 8, and the limiting ring 8 is fixed in the mounting holes 7 through the fixing holes 9 in a screwed mode.

In this embodiment, as shown in fig. 1, 2, and 3, lubricating oil is injected into the inner side of the outer ring 4 through the oil inlet 6 to lubricate the needle roller 5.

The shaft center 2 is located at the top of the surface of the inner ring 1, the inner wall of the shaft center 2 is adhered with an anti-abrasion pad 3, and the anti-abrasion pad 3 is made of rubber materials.

In the embodiment, as shown in fig. 1 and 2, the wear pad 3 is used to improve the installation stability of the shaft core 2.

The periphery of the inner side surface of the limit ring 8 is uniformly provided with ball grooves 10 around the center, and the ball grooves 10 are filled with balls 11.

In this embodiment, as shown in fig. 1 and 3, the balls 11 filled in the ball grooves 10 move in cooperation with the needle rollers 5.
