Abstract

The utility model relates to a stamping self-aligning clutch release bearing, which comprises a sleeve, an inner ring located outside the sleeve, an outer ring located outside the inner ring, an outer cover mounted on the outer ring, a plurality of steel balls located between the inner ring and the outer ring, a retainer which separates the steel balls, and a rubber sealing ring clamped between the outer cover and the inner ring, wherein the sleeve is made of wear-resistant materials, lots of axial grooves are distributed on the inner circle of the sleeve uniformly, a tooth-shape spring gasket is arranged between the outer ring and the sleeve, and the retainer is made of reinforced nylon. The utility model has the advantages of low wear, fine sealing, long service life and high material utilization efficiency, and further, the rotation center of the bearing and the center of the release mechanism are aligned by eccentric torque generated when a diaphragm spring contacts with the bearing, thereby greatly reducing wear between the diaphragm spring and the release bearing.

Description

A kind of punching press self-aligning separable bearing of clutch

(1) technical field

The utility model belongs to bearing, particularly a kind of punching press self-aligning separable bearing of clutch.

(2) background technique

Along with the development of automobile industry, the increase of automobile pin, the amount of selling, the shortcoming of conventional vehicle clutch disengaging bearing embodies gradually, as: the matching allowance of bearing support and bearing is too big, and it is stuck to make bearing release bearing in use occur, ablation phenomenon.And traditional release bearing is outer ring rotation, and do not have aligning, and outer ring rotation limit speed is low, and sleeve adopts cast iron sleeve.There is a problem that product designers are felt a delicacy about for many years always---the center line decentraction of clutch assembly center and automatic power drive assembly and release bearing.So clutch release bearing is aspect development such as lightweight on such as element of constructionization, integrated, volume miniaturization, weight, performance speed up and high reliability, low noise, long lifetime gradually, have researched and developed Kia, the automobile-used clutch release bearing in Mazda.

(3) summary of the invention

The utility model is in order to remedy the deficiencies in the prior art, and a kind of low, life-span length of wearing and tearing, good seal, in light weight, punching press self-aligning separable bearing of clutch that rotating speed is high are provided.

The utility model is achieved by the following technical solution:

Punching press self-aligning separable bearing of clutch of the present utility model, comprise sleeve, at the inner ring of sleeve outside, in the outer ring of inner ring outside, be installed in the outer cover on the outer ring, the plurality of steel balls between inner ring and outer ring, the retainer of spacer ball, its special way is: accompany rubber seal between outer cover and the inner ring; Sleeve is made by wear-resistant plastic, is evenly distributed with a large amount of axial grooves on the sleeve diameter; Be provided with the profile of tooth spring washer between outer ring and the sleeve; Retainer is made by Reinforced Nylon.

The beneficial effects of the utility model are: it is low to wear and tear, good seal, life-span is long, change the inner ring rotation into by traditional bearing outer ring rotation, and inner ring, outer ring are modified into punch process by forging processing and form, and do not need to carry out turning processing, the utilization ratio height of material, simplify processing technology, reduced cost of production; Weight is reduced to 120g from the 220g of original product, has alleviated 45%; Adopted wear resistant plastic material to make bearing sleeve, plastic sleeve has the effect of vibration-absorbing denoising, so can reduce bearing vibration and noise, wear extent has reduced half; Change the outer cover that has the rubber seal circle into by the punching press outer cover, cooperate with the rib of inner ring, sealing improves the bearing seal effect between inner ring and the bearing outer cover.Because inner ring keeps radial floating with respect to separating mechanism, the eccentric moment that produces when diaphragm spring contacts with bearing makes the center of bearing rotating center and separating mechanism, has significantly reduced the wearing and tearing of diaphragm spring and release bearing; Prolonged bearing working life; Reduced the sliding friction of sleeve effectively, the circulation of lubricating grease is improved, and has guaranteed the working life of bearing, and has improved sealing.Be provided with the profile of tooth spring between bearing outer ring and the release sleeve, release bearing is done radially to adjust in sleeve, makes clutch and release bearing reach coaxial purpose; Reinforced Nylon 66 retainers are isolated steel ball effectively.That is to say from the rotation of no aligning, outer ring, the product of cast iron sleeve, develop into have the self-aligning performance, high speed, the high reliability bearing unit of inner ring rotation, punched outer housing and punching press sleeve or plastic sleeve.

(4) description of drawings

Fig. 1 is the structural representation in the utility model longitudinal section.

Among the figure, 1 inner ring, 2 outer covers, 3 steel balls, 4 outer rings, 5 retainers, 6 profile of tooth spring washers, 7 sleeves, 8 rubber seal.

(5) embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model.

Punching press self-aligning separable bearing of clutch of the present utility model, comprise sleeve 7, at the inner ring 1 of sleeve outside, in the outer ring 4 of inner ring outside, be installed in the outer cover 2 on the outer ring, the plurality of steel balls 3 between inner ring and outer ring, the retainer 5 of spacer ball, accompany rubber seal 8 between outer cover and the inner ring; Sleeve is made by wear-resistant plastic, is evenly distributed with a large amount of axial grooves on the sleeve diameter; Be provided with profile of tooth spring washer 6 between outer ring and the sleeve; Retainer is made by Reinforced Nylon.It is prior art that part is not described in detail in detail.

Principle from aligning is eccentrically the inner ring of bearing to be drawn in the clutch compressing disc center line by clutch diaphragm spring not have relative movement to realize up to two contact surfaces.The punching press self-aligning separable bearing of clutch is further promoted the use of, and has solved a problem that for many years product designers is felt a delicacy about---the center line decentraction of clutch assembly center and automatic power drive assembly and release bearing.

Claims

1. punching press self-aligning separable bearing of clutch, comprise sleeve (7), be positioned at the sleeve outside inner ring (1), be positioned at the inner ring outside outer ring (4), be installed in the retainer (5) of outer cover (2) on the outer ring, the plurality of steel balls between inner ring and outer ring (3), spacer ball, it is characterized in that: accompany rubber seal (8) between outer cover and the inner ring; Sleeve is made by wear-resistant plastic, is evenly distributed with a large amount of axial grooves on sleeve (7) internal diameter; Be provided with profile of tooth spring washer (6) between outer ring and the sleeve; Retainer is made by Reinforced Nylon.
