Bearing retainer

Technical Field

The utility model belongs to the technical field of the bearing, especially, bearing retainer.

Background

The ball bearing is one kind of rolling bearing, and the ball bearing is installed in the middle of inner steel ring and outer steel ring and can bear great load. At present, on the less ball bearing of width, often can fix the steel ball on the holder and combine with the shield and realize the whole sealed (as figure 1) of bearing, but this kind of bearing, need design the shield earlier, adjust bearing inner space through changing the steel ball size to it is limited to be applicable to the bearing width, therefore this kind of design often makes the inside steel ball of bearing less, and not only the installation is inconvenient, has the weak problem of bearing capacity moreover, thereby leads to its range of application greatly reduced. In addition, there is a drawback that the dust cap is easily deformed.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a be applied to the less ball bearing of width, can improve the bearing retainer of ball bearing capacity and application range.

In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a bearing retainer, includes the holder body, the holder body is including the skeleton that is used for the steel ball installation location, the terminal surface of skeleton edge axial both sides is connected with first apron and second apron respectively, the terminal surface towards first apron on the skeleton has a plurality of pockets holes that are used for the steel ball installation location along its circumference equipartition, the radial thickness of first apron, second apron and skeleton is the same.

By adopting the scheme, in the using process, the steel ball is firstly placed in the raceway of the bearing (namely the raceway between the inner ring and the outer ring) and the inner ring and the outer ring are fixed, then the framework is pressed into the bearing, so that the steel ball can enter the pocket hole of the framework, the first cover plate and the second cover plate are respectively pressed into the end faces at the two sides of the framework and are connected with the first cover plate and the second cover plate, the steel ball can be stably arranged in the raceway through the framework, the first cover plate and the second cover plate, and the first cover plate, the second cover plate and the framework have the same radial thickness, so that the steel ball can be matched with the inner ring and the outer ring of the bearing for use, the bearing can directly form sealing through the retainer body without additionally arranging a dust-proof cover, the internal space structure cannot be influenced by the dust-proof cover, the size of the steel ball can also be adaptively changed, and the bearing capacity of the bearing can still be improved by changing the size of the, and the dust-proof device is convenient to install, has a stable structure and has a certain dust-proof effect.

As a further setting of the utility model, be provided with a plurality of grafting knots that are used for connecting skeleton and first apron between skeleton and the first apron, grafting knot is including the grafting axle and the spliced eye that can peg graft mutually, grafting axle and spliced eye divide and establish on skeleton and the first apron, a plurality of grafting knots correspond the setting respectively between pocket hole and pocket hole.

Adopt above-mentioned scheme, the plug spindle and the spliced eye through pegging graft mutually form the cooperation of pegging graft, and not only easy to assemble can make first apron and skeleton form fixed connection moreover, and the lid through first apron closes and can prevent that the steel ball from deviating from in the pocket hole, stability when improving the bearing and roll.

As a further setting of the utility model, the skeleton has a plurality of lugs along the circumference equipartition towards the terminal surface of second apron, the lug is provided with first slot on the terminal surface of second apron, the position that corresponds first slot on the second apron is provided with the first inserted block of grafting complex with first slot, the inner wall of first slot is provided with the anticreep piece, be provided with on the first inserted block and be used for preventing the anticreep barb that the second apron is deviate from with the cooperation of anticreep piece.

Adopt above-mentioned scheme, through setting up first slot on the lug, then through the first inserted block that sets up on the second apron, first inserted block and first slot are pegged graft the cooperation and can be prevented that the relative skeleton of second apron from deviating from, improve the stability of product structure, set up anticreep barb and anticreep piece respectively at the inner wall of first inserted block and first slot in addition and can further improve the anticreep performance for the second apron is more firm with the skeleton joint, prevents to rotate and deviates from.

As a further setting of the utility model, be provided with the storage tank between lug and the lug, be provided with the one-way turning block in the storage tank, the lug is provided with the second slot that communicates with the storage tank on the terminal surface of second apron, the position that corresponds the second slot on the second apron is provided with the second inserted block of grafting complex with the second slot, it supports the spring of establishing between one-way turning block and second slot inner wall to be provided with an elasticity in the second slot.

Adopt above-mentioned scheme, through set up one-way turning block on the skeleton for some occasions that need one-way rotation can be applied to the holder, further improve the range of application of product, because one-way turning block receives supporting of spring to establish, consequently can install in the storage tank steadily, also make one-way turning block's dismouting become very convenient like this. In addition, the spring setting can play limiting displacement to the spring after the second inserted block inserts the second slot in the second slot, prevents that the spring from deviating from. By adopting the structure, the installation is convenient, and the purpose that the bearing can realize unidirectional rotation by the unidirectional rotating block is ensured.

The present invention will be further described with reference to the accompanying drawings.
