Abstract

The utility model relates to a novel bakelite retainer for a low noise bearing. The utility model is characterized in that the retainer uses a two-half type structure, the two-half retainer (1) is provided with a plurality of rivet holes which are evenly distributed, and the rivet holes are riveted and fixed through rivets (2); the outer part of a rivet rod is provided with a sleeve cylinder (3) which is tightly matched and connected with through holes of the rivets of the retainer, and the upper and the lower ends of each rivet hole are provided with counterbored holes; the upper and the lower ends of each rivet are tightly riveted on the plane surfaces of concave tables of the two counterbored holes through pad sheets (4), and a plurality of through holes of straight pockets, which are evenly distributed, are arranged on the retainer. The utility model can realize normal sound under the condition of low vibration, low noise and rotation by changing the materials, the structure and the manufacturing method of the bearing retainer, and the self lubrication and the corrosion resistance in the state of oil starvation can be realized.

Description

Novel low-noise sound deep groove ball bearing bakelite retainer

Technical field:

The utility model relates to technical field of rolling bearings, a kind of novel low-noise sound deep groove ball bearing bakelite retainer.

Background technique:

Motor is when proper functioning, can produce noise, the quality of the size of noise and rotor bearing is closely related, and the quality of retainer directly has influence on the quality of bearing, in the process of exploitation motor, require retainer must have low vibration, low noise, no abnormal sound during rotation with the low noise deep groove ball bearing, and corrosion resistant characteristics can be lubricated under the oil starvation state.

The present bearing bakelite retainer of producing of China can't satisfy above-mentioned requirements.

Summary of the invention:

In order to overcome deficiency of the prior art, the purpose of this utility model provides a kind of novel low-noise sound deep groove ball bearing bakelite retainer, by change to bearing holder material, structure and manufacture method, no abnormal sound in the time of can realizing low vibration, low noise, rotation, and can selflubricating and corrosion-resistant under the oil starvation state.

In order to realize the foregoing invention purpose, the utility model adopts following technological scheme:

This novel low-noise sound deep groove ball bearing bakelite retainer, its retainer adopt two halves formula structure, and two halves formula retainer is provided with several equally distributed rivet holes, fixes by rivet; There is sleeve outside at rivet bar, adopts drive fit to be connected between sleeve and the retainer rivet through hole; Rivet hole has counterbore in two ends up and down, and the rivet upper and lower end is riveted tightly on two counterbore concave station planes by pad; Also be provided with several equally distributed straight pocket through holes on its retainer.

This novel low-noise sound deep groove ball bearing bakelite retainer, its two halves retainer adopt has absorbing, oil suction, effective vibration and noise reducing, the phenolic aldehyde compress bakelite material of lubrication effect under the oil-poor state; Its rivet, sleeve and pad adopt the stainless steel material with good rust-proof effect.

Owing to adopted technique scheme, the utlity model has following good effect:

This novel low-noise sound deep groove ball bearing bakelite retainer, because it has adopted phenolic aldehyde compress bakelite material, this material has characteristics such as absorbing, oil suction, can effectively realize vibration damping, noise reduction, the lubricated effect of fuel-economizing, because the bakelite mechanical strength is lower, be provided with counterbore at the retainer end face,, improve its mechanical strength defect of insufficient to increase the width of retainer; Its rivet, sleeve and packing ring all adopt stainless steel material, can reach good anticorrosion ability, because stainless steel material hardness is higher, can not guarantee total quality when adopting the normal temperature riveted, so adopt hot riveting technique, the phenomenon that in the rivet hot process, very easily causes retainer to be burnt out, so be provided with sleeve and pad at rivet and retainer contact segment, the assurance rivet hot is finished smoothly; In addition, between sleeve and the retainer rivet hole, adopt drive fit both to improve retainer intensity, avoided the harmful effect of the vibration that causes because the pocket hole misplaces, noise, abnormal sound again.

In the occasion that this retainer can be widely used in vibration, noise, corrosion resistance are had relatively high expectations: as motor bearings, precision bearing, noise-free bearing, naval vessel bearing, application and development prospect in market is quite wide.

The drawing explanation:

Fig. 1 is a novel low-noise sound deep groove ball bearing bakelite retainer part sectioned view:

As shown in FIG.: 1-half retainer, 2-rivet, 3-sleeve, 4-pad.

Specific embodiment:

This novel low-noise sound deep groove ball bearing bakelite retainer, its retainer adopt two halves formula structure, and two halves retainer (1) is provided with several equally distributed rivet holes, by rivet (2) riveted fixing; Sleeve (3) is arranged in the outside of rivet bar, adopt drive fit to be connected between sleeve and the retainer rivet through hole; Rivet hole has counterbore in two ends up and down, and the rivet upper and lower end is riveted tightly on two counterbore concave station planes by pad (4); Also be provided with several equally distributed straight pocket through holes on its retainer.

Half retainer has adopted phenolic aldehyde compress bakelite material, and its rivet, sleeve, pad adopt stainless steel material to make, because stainless steel material hardness is higher, adopts hot riveting technique during half retainer riveted.
