Description
Technical field
The utility model is related to technical field of bearing processing, especially a kind of built-in self-sustaining expire roller cage component and
Its speed reducer.
Background technology
The bearing that radial roller and retainer component in robot speed reducer are constituted is because its running accuracy is high, load
Greatly, there is prodigious market using field in some bearings, but since Bearing inner is limited by space, structure type usually has
" M " type retainer and roller assembly structure, " door " word fall off type retainer and roller assembly structure, the inside and outside modeling without retainer
Material set completely fills roller structure；Metal is punched retainer because roller quantity has the risks such as processing difficulties, qualification rate be low more；It is installing
In the case that space limits, existing full type roller bearing is generally without retainer, when use directly between two parts
Roller is plugged, however without the full dress roller structure of retainer is limited before roller assembles and transported using inside and outside plastic sheath
Fall needle in journey, while in use since roller does not have the guiding of retainer, it is right there are larger axial force in rotation
The service life of bearing and rotating speed are all prodigious influences, limit the use of bearing.
Utility model content
The technical problems to be solved in the utility model is：It is easy needle in order to solve full type roller bearing in the prior art and does not have
The problem of having the guiding of retainer there are larger axial force in rotation, and the service life and rotating speed to bearing produce bigger effect,
Now providing a kind of built-in self-sustaining expires roller cage component and its speed reducer, which, which may be implemented in, does not have
In the case of outer ring and inner ring, realizes the self-locking to roller thereon using retainer itself, prevent roller falling on retainer
It falls.
Technical solution adopted by the utility model to solve its technical problems is：Roller cage is expired in a kind of built-in self-sustaining
Component, including retainer and multiple rollers, the retainer include two baffles annular in shape and are connected between two baffles
Outer crossbeam and interior crossbeam；
The outer crossbeam has several and is uniformly distributed along the circumferencial direction of baffle, and being formed between two neighboring outer crossbeam can
Limit the outer fore shaft of single roller, the quantity of outer fore shaft is consistent with the quantity of roller on the retainer and corresponds；
The interior crossbeam has several and is uniformly distributed along the circumferencial direction of baffle, and the interior crossbeam is located at the interior of outer crossbeam
Side, forms the interior fore shaft that can limit two rollers between two neighboring interior crossbeam, and the quantity of interior fore shaft is outer on the retainer
The half of fore shaft quantity；
Fore shaft is opposite in the two adjacent outer fore shafts of retainer radially with it in each, and each outer fore shaft is corresponding thereto
Interior fore shaft between be respectively formed pocket hole for accommodating single roller, the roller is filled in the pocket hole, the roller
Outside protrudes from the lateral surface of outer crossbeam from outer fore shaft, and the inside of the roller protrudes from the medial surface of interior crossbeam from interior fore shaft.
Axial restraint is carried out to roller using two baffles in this programme, reduces the axial force in bearing operation, roller
Outside is limited by outer fore shaft, prevents it from falling off from pocket hole, and the inside of roller is limited by interior fore shaft, prevents it from pocket
It falls off in hole, wherein interior fore shaft can limit two rollers simultaneously, i.e. two rollers share an interior fore shaft, can be convenient for roller
It is packed into pocket hole.
Further, the material of the retainer is PA46 or PA66, i.e., retainer is made by material PA46 or PA66
Plastic cage, the high temperature resistant and strength character of retainer can be improved, be convenient for retainer processing.
Further, the retainer is integrally formed.
The utility model also provides a kind of speed reducer, and there is above-mentioned built-in self-sustaining to expire roller cage component.
The utility model has the beneficial effects that：Roller cage component is expired in the built-in self-sustaining of the utility model has Gao Cheng
Loading capability not only realizes the assembly on retainer convenient for roller, but also can prevent roller from being fallen from retainer, solves
Roller is crooked in existing full type roller bearing, falls the problem of needle, improves the reliability of bearing installation, while the guiding function of retainer
Also the axial force of the full type roller bearing can be made to obtain prodigious reduction, improves service life and the use scope of full type roller bearing.
