Description

A kind of elastic slice bearing

Technical field

The utility model relates to a kind of bearings, and in particular to a kind of elastic slice bearing.

Background technique

Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is to support mechanical rotary body, is reduced Coefficient of friction in its motion process, and guarantee its rotating accuracy.According to the difference of the friction properties of the moving elements, bearing can be divided into rolling Dynamic bearing and sliding bearing two major classes.Wherein rolling bearing is normalized, seriation, but its radial direction compared with sliding bearing Size, vibration and noise are larger, and price is also higher.By the shape of rolling element, rolling bearing is divided into ball bearing and roller bearing two Major class.But existing bearing installation not enough consolidates, and movement is easy, without axial buffer, intolerant to abrasion.

Utility model content

The utility model provides a kind of elastic slice bearing, with solve bearing noise of the existing technology it is big, intolerant to abrasion Problem.

In order to solve the above technical problems, the utility model provides a kind of elastic slice bearing, including bearing outer ring, bearing inner race, Retainer, steel ball, wherein the bearing outer ring inner wall is provided with the first raceway；The bearing inner race outer wall is provided with the second rolling Road, first raceway and the second raceway are symmetrical；The bearing inner race is embedded in the bearing outer ring, and the steel ball passes through guarantor Frame is held to be fixed in the gap between the first raceway of bearing outer ring and the second raceway of bearing inner race；The retainer with it is described Steel ball corresponds, and the steel ball can slide in the retainer；It further include butterfly elastic slice, the butterfly elastic slice is installed on institute It states in bearing outer ring, and is connect with the bearing inner race.

The elastic slice bearing is axially installed with plastic bushing, and the plastic bushing connects the inner wall of bearing inner race, and described Plastic bushing is equipped with the baffle of protrusion along the axis direction of bearing.

The butterfly elastic slice is made of stainless steel material.

The utility model bring the utility model has the advantages that the utility model elastic slice bearing, structure is simple, easy for installation, internal Plastic bushing and axis install, butterfly elastic slice is installed in the bearing outer ring, and is connect with the bearing inner race, plastic bushing Play the role of fixed with butterfly elastic slice and buffer, when load is excessive, metal position will not deform, and plastic components buffering becomes Shape, noise is small, wear-resistant, so that bearing installation is more firm, it is not easily shifted.

Wherein, 1- bearing outer ring, 2- bearing inner race, 3- retainer, 4- steel ball, 5- butterfly elastic slice, 6- plastic bushing, 7- gear Piece.

Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with drawings and the specific embodiments, The utility model is described in further detail.

Fig. 3 is the A-A of Fig. 2 to diagrammatic cross-section.

The utility model provides a kind of elastic slice bearing, including bearing outer ring 1, bearing inner race 2, retainer 3, steel ball 4, In, 1 inner wall of bearing outer ring is provided with the first raceway；2 outer wall of bearing inner race is provided with the second raceway, first rolling Road and the second raceway are symmetrical；The bearing inner race 1 is embedded in the bearing outer ring 2, and the steel ball 4 is fixed by retainer 3 In gap between the first raceway of bearing outer ring and the second raceway of bearing inner race；The retainer 3 and the steel ball 4 one One is corresponding, and the steel ball can slide in the retainer 3；It further include butterfly elastic slice 5, the butterfly elastic slice 5 is installed on described In bearing outer ring 1, and it is connect with the bearing inner race 2.

Furthermore, it is understood that the elastic slice bearing is axially installed with plastic bushing 6, the plastic bushing 6 connects bearing inner race Inner wall, and the plastic bushing 6 along bearing axis direction be equipped with protrusion baffle 7.

The butterfly elastic slice 5 is made of stainless steel material.

In the present embodiment, when product is installed and used, axial level pressure is pre-tightened, and eliminates the internal clearance of bearing；Bearing is normal When work, internal gapless, assembly is not in shake when vibration；Since level pressure pre-tightens, the inner ring of product, steel ball and Outer ring is unanimously in the state of fitting；Internal plastic bushing can play the role of insulation, and the galvanic corrosion for preventing assembly to be powered is existing As；Internal plastic bushing and axis is installed, and is played the role of fixed and is buffered, when load is excessive, metal position will not become Shape, plastic components buffering deformation.

Product installs and uses the support end in turbine and worm, can make up back lash caused by turbine and worm temperature distortion Variation；Gap-adjusting structure can eliminate the unstable phenomenon of engagement caused by the machining accuracy of turbine and worm；Gap-adjusting structure can guarantee Internal ball bearing will not send out inclination, cause abnormal sound or the service life decline of bearing products；Gap-adjusting structure is impacted in assembly When, the buffer function to internal ball bearing can be played, while protecting the impact of turbine and worm, cause tooth form damaged；In turbine When worm mechanism is worn, adjust gap bearing that can make up the wearing clearance of turbine and worm；Product not only has the rotation function of bearing, Also have the function of sliding bearing, it can be with the movement of fixed direction small distance.

In conclusion the elastic slice bearing of the utility model, structure is simple, easy for installation, and internal plastic bushing and axis are pacified Dress, butterfly elastic slice is installed in the bearing outer ring, and is connect with the bearing inner race, and plastic bushing and butterfly elastic slice play admittedly Fixed and buffering effect, when load is excessive, metal position will not deform, plastic components buffering deformation, so that bearing is installed It is more firm, it is not easily shifted.

The above description is only the embodiments of the present invention, is not intended to limit the utility model, for this field Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model, Any modification, equivalent replacement, improvement and so on should be included within the scope of the claims of the utility model.
