Abstract
The utility model discloses a roll ball type universal coupling provided with sliding blocks. The roll ball type universal coupling comprises an inner gear sleeve, sliding blocks, an outer gear shaft and joint bearings, wherein a plurality of slideways are arranged in an inner hole of the inner gear sleeve; roll ball slideways are arranged on the side surfaces of the slideways; one sliding block is arranged in each slideway; roll ball grooves are formed in two side surfaces of each sliding block; a plurality of steel balls are arranged in each roll ball groove of the sliding blocks; the parts, bulged out of the roll ball grooves, of the steel balls are embedded into the corresponding roll ball slideways; a shaft fork is arranged on each sliding block and faces the center of the inner hole of the inner gear sleeve; inner sleeves of the joint bearings are mounted on the shaft forks; outer rings of the joint bearings are mounted at the shaft end of the outer gear shaft; and the inner sleeves of the joint bearings are arranged in the corresponding outer rings of the joint bearings in a sleeving manner. According to the roll ball type universal coupling provided with the sliding blocks, the plurality of steel balls are mounted in each roll ball groove of the sliding blocks, the bearing pressure of each steel ball is greatly reduced, so that pressure of each contact point on each raceway surface is greatly reduced, and the service life of the roll ball type universal coupling is greatly prolonged; and besides, the maintenance cost is low.
Description
Technical field
The utility model relates to a kind of ball type Hooks coupling universal coupling, relates to specifically a kind of slide block type ball universal coupling.
Background technique
In mechanical system, in the time that interconnective diaxon has angular displacement, often realize the connection between diaxon with Hooks coupling universal coupling.The more Hooks coupling universal coupling of application has drum type tooth type universal coupling, universal coupling with spider and ball type Hooks coupling universal coupling now.The power transmission medium of existing ball type Hooks coupling universal coupling is steel ball, because coupling has universal requirement, each raceway can only be installed a steel ball, therefore in the time of work, roller surface will bear very large pressure, and serious wear, be easy to cause roller surface press collapse formula damage, thereby cause steel ball not roll, whole coupling can not be realized universal requirement and scrap, and makes the working life of coupling very short.And existing ball universal coupling has only been installed parts, after destruction, will entirety scrap, and cost is high.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of simple in structure, long service life, slide block type ball universal coupling that maintenance cost is low.
The technical solution adopted in the utility model is: comprise internal tooth casing, slide block, external tooth axle and joint shaft bearing, in the endoporus of described internal tooth casing, be provided with multiple slideways, the side of slideway is provided with ball slideway, in described each slideway, be equipped with slide block, on the bi-side of slide block, be equipped with ball grooves, in each ball grooves of slide block, be provided with multiple steel balls, steel ball protrudes ball grooves part and is embedded in corresponding ball slideway, described each slide block is provided with yoke, yoke is towards internal tooth casing endoporus center, the inner sleeve of joint shaft bearing is all installed on yoke, the outer ring of joint shaft bearing is arranged on the axle head of external tooth axle, the inner sleeve of joint shaft bearing is sleeved in the outer ring of corresponding joint shaft bearing.
In above-mentioned slide block type ball universal coupling, in the endoporus of described internal tooth casing, be provided with 3-4 slideway.
In above-mentioned slide block type ball universal coupling, in the ball grooves of described slide block side, be provided with 3 steel balls.
Compared with prior art, the beneficial effects of the utility model are:
1, in each ball grooves of slide block of the present utility model, many steel balls are housed, therefore, each steel ball bear pressure with respect to the carrying of single steel ball time pressure greatly reduce, thereby on every roller surface, every point of contact pressure greatly reduces, and greatly extended working life of the present utility model.
2, slide block is easily damaged parts, but its cost of material of occupying is little, and processing is simple, and existing ball coupling has only been installed parts, will entirety scrap, and the utility model only need be changed slide block after destruction, and maintenance cost is low.
3, joint shaft bearing of the present utility model is standard piece, can order, and makes the utility model easy to maintenance, simple and easy, has reduced cost of production, has reduced maintenance cost.
