Description
Technical field
The utility model is related to technical field of bearing processing, especially filling roller cage component and its deceleration in one kind
Machine.
Background technology
The bearing that radial roller and retainer component in speed reducer are constituted because its running accuracy is high, load is big,
Some bearings have prodigious market using field, 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 plastic sheath without retainer
Completely fill roller structure；Metal is punched retainer because roller quantity has the risks such as processing difficulties, qualification rate be low more；In installation space
In the case of limitation, generally without retainer, when use, directly plugs between two parts existing full type roller bearing
Roller, however without the full dress roller structure of retainer limited before roller assembles and in transportational process using inside and outside plastic sheath
Fall needle, while in use since roller does not have the guiding of retainer, there are larger axial forces in rotation, to bearing
Service life and rotating speed be all prodigious influence, 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 provide in one kind and filling roller cage component and its speed reducer, the full roller cage component may be implemented in no outer ring and
In the case of inner ring, using interior plug sleeve can by roller locks in retainer, prevent roller before assembly in transportational process from guarantor
Hold falling on frame, but can eliminate assembly in roller is crooked, falls the shortcomings that needle, while can guide rolls movement, reduce axis
To the rotating speed of power and raising bearing.
Technical solution adopted by the utility model to solve its technical problems is：Roller cage component is filled in one kind,
Including retainer, interior plug sleeve and multiple rollers, the retainer include two baffles annular in shape and be connected to two baffles it
Between outer 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, described
Roller is corresponded to loaded in outer fore shaft, and the outside of the roller protrudes from the lateral surface of outer crossbeam from outer fore shaft；
Running through on two baffles has inner ring hole, and the interior plug sleeve is plugged in the inner ring hole of the baffle, described
Roller is respectively positioned between interior plug sleeve and outer crossbeam, and the inside of the roller is contacted with the peripheral surface of interior plug sleeve.
Axially position 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, and the inside of roller is fixed by interior plug sleeve, effectively avoids bearing before assembly
With the problem of generation roller is fallen in transportational process, wherein roller can be easily packed into from the inside of retainer.
Further, interior reinforcing rib is fixed between two baffles, the interior reinforcing rib there are several and along baffle
It is circumferentially distributed, the interior reinforcing rib is located at the inside of outer crossbeam, it is each in reinforcing rib be respectively positioned between two adjacent rollers,
The medial surface of interior reinforcing rib adjacent thereto is protruded from the inside of the roller, at least three between adjacent two interior reinforcing ribs
A roller, interior reinforcing rib can also have certain holding effect other than it can increase the intensity of retainer to roller.
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 material of the interior plug sleeve is PP (polypropylene), i.e., interior plug sleeve is in the plastics made by material PP
Plug sleeve.
Further, the retainer is integrally formed.
The utility model also provides a kind of speed reducer, has in above-mentioned and fills roller cage component.
The utility model has the beneficial effects that：Roller cage component is filled in the utility model passes through retainer and interior
Roller is fixed for the cooperation of plug sleeve, while keeping the high bearing capacity of full type roller bearing, solves in full type roller bearing
Needle roller is crooked, falls the problem of needle, improves the reliability of bearing installation, while the guiding function of retainer is but also full Roller Shaft
The axial force held obtains prodigious reduction, improves service life and the use scope of full type roller bearing.
