Description
Technical field
The utility model relates to a kind of bearing, specifically a kind of weaving machine bearing belongs to bearing arrangement technical field.
Background technique
In the prior art, for textile machine bearing mainly by outer ring, inner ring, rolling element, retainer, sealing ring, grease
Deng composition.Using rolling element is installed between outer ring and inner ring, rolling element uses ball-type, be evenly distributed on outer ring and inner ring it
Between, it is fixed up with a retainer, sealing ring plays the role of dust-proof and prevents grease leakage, and grease plays lubrication and forms oil
The effects of film.But because bearing is that axis rotates and sealing ring is contactless structure（There is gap between inner ring and sealing ring）, due to
It is more to make steam, dust in operating condition used in frame, easily enters Bearing inner, such sealing effect is not axis very well
Hold easy failure.
Summary of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of weaving machine bearing, bearing inner race
It is received in bearing outer ring in both ends of the surface, improves the dust-proof effect of bearing, improve the service life of bearing.
According to technical solution provided by the utility model, a kind of weaving machine bearing includes bearing inner race, bearing outer ring, holding
Frame, ball and dustproof cover are equipped with bearing inner race in bearing outer ring inner cavity, be equipped between bearing inner race and bearing outer ring retainer and
Ball, ball are located in retainer, and ball rear and front end is equipped with dustproof cover, it is characterized in that：It is received in the left and right end face of bearing inner race
In bearing outer ring inner cavity；Dustproof cover inner ring is sleeved on bearing inner race outer surface, dustproof cover inner ring and bearing inner race outer surface it
Between for interference fit, between dustproof cover outer ring and bearing outer ring inner surface be equipped with certain gap.
Further, interstice coverage is 0.2 ~ 0.25mm between dustproof cover outer ring and bearing outer ring inner surface.
Further, it is set on bearing inner race inner surface there are two dust-proof groove, two dust-proof grooves are located at the outer of dustproof cover
Side.
Compared with the prior art the utility model has the following advantages that：
The utility model structure is simple, compact, reasonable, is received in bearing outer ring in bearing inner race both ends of the surface, improves axis
The dust-proof effect held improves the service life of bearing；Dust-proof groove is set in bearing outer ring inner sidewall, increases dust entrance
The path of Bearing inner, improves dust-proof effect.
Detailed description of the invention
Fig. 1 is the utility model main view.
Description of symbols：1- bearing inner race, 2- bearing outer ring, 3- retainer, 4- ball, 5- dustproof cover, the dust-proof ditch of 6-
Slot.
Specific embodiment
The utility model will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1, the utility model mainly includes bearing inner race 1, bearing outer ring 2, retainer 3, ball 4 and dustproof cover
5。
It is equipped with bearing inner race 1 in 2 inner cavity of bearing outer ring, is received in 2 inner cavity of bearing outer ring in the left and right end face of bearing inner race 1
In.
Retainer 3 and ball 4 are equipped between bearing inner race 1 and bearing outer ring 2, ball 4 is located in retainer 3.Before ball 4
Both ends are equipped with dustproof cover 5 afterwards, and 5 inner ring of dustproof cover is sleeved on 1 outer surface of bearing inner race, 1 appearance of 5 inner ring of dustproof cover and bearing inner race
It is interference fit between face.Certain gap is equipped between 2 inner surface of 5 outer ring of dustproof cover and bearing outer ring.
Interstice coverage is 0.2 ~ 0.25mm between 5 outer ring of dustproof cover and 2 inner surface of bearing outer ring.
It is set on 1 inner surface of bearing inner race there are two dust-proof groove 6, two dust-proof grooves 6 are located at the outer of dustproof cover 5
Side.
The working principle of the utility model is：It is received in bearing outer ring in bearing inner race both ends of the surface, axis is received in dustproof cover
In bearing outer-ring, dust more disagrees the dust-proof effect that bearing is improved into Bearing inner, and improve bearing uses the longevity
Life；Dust-proof groove is set in bearing outer ring inner sidewall, increases the path that dust enters Bearing inner, improves dust-proof effect.
