Abstract

The invention provides a bearing inner ring which is used in a bearing. The bearing comprises a bearing outer ring matched with the bearing inner ring, a bead positioned between the bearing outer ring and the inner ring, and a dustproof cover sleeved between the bearing outer ring and the bearing inner ring, wherein the bearing inner ring is provided with a contact surface which is connected with the dustproof cover; and the contact surface is of an inward inclined shape. According to the bearing inner ring, the contact surface of the bearing inner ring is contacted with the dustproof cover, and as the contact surface inclines inwards, when fine dust enters the bearing, the dust is accumulated in the region formed by the inclined shape of the contact surface, so that the contact surface plays a buffering and retarding role on the bearing; and dust which enters the bearing is extremely fine, so that the service life of the bearing is ensured.

Description

A kind of bearing inner race
Technical field
The present invention relates to a kind of bearing, relate in particular to a kind of bearing inner race.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.
Like the structural representation of Fig. 1 for bearing existing; Bearing 100 comprises: bearing outer ring 10, the bearing inner race in bearing outer ring 10 20, be fixed on retainer 40 between bearing outer ring 10 and the bearing inner race 20, be fixed on the plurality of balls 30 on the retainer 40 and be set in bearing outer ring 10 and bearing inner race 20 between dust cover 50; First end 51 of dust cover 50 is fixed on the bearing outer ring 10; Second end 52 of dust cover 50 is fixed on the bearing inner race 20, so that it is inner to prevent that dust from getting into bearing.
Bearing sometimes need be in the working environment work of many dusts; Though general bearing all is provided with dust cover; But it is inner that general small dust still gets into bearing through dust cover and bearing inner race 20 contacting points, and this is because bearing inner race 20 is smooth with the position that second end 52 of dust cover 50 contacts, and it is inner to cause tiny dust still to be very easy to get into bearing; With the minimizing in working life of causing bearing, cost of idleness.
Summary of the invention
Order of the present invention is to provide a kind of and is skewed, has buffering, retardation with the dust cover contact position, thereby guarantees the bearing inner race in the working life of bearing.
Of the present invention a kind of bearing inner race is provided; Be used in the bearing; Bearing comprise the bearing outer ring that cooperates with bearing inner race, the ball between bearing outer ring and the inner ring and be set in bearing outer ring and bearing inner race between dust cover; Said bearing inner race is provided with the surface of contact that joins with dust cover, and this surface of contact is recessed to the central shaft of bearing.
Wherein, said surface of contact comprises that the central shaft with bearing has first of angle [alpha] and have second of angle beta with the Y axle, and first is connected with second, and the Y axle is vertical with the central shaft of bearing.
Wherein, angle [alpha] is spent less than 15 greater than 5 degree.
Wherein, angle [alpha] is 10 degree.
Wherein, angle beta is spent less than 60 greater than 30 degree.
Wherein, angle beta is 45 degree.
Wherein, dust cover has first end that fixes with bearing outer ring and second end that fixes with bearing inner race.
The present invention is through being provided with the surface of contact that joins with dust cover at bearing inner race; This surface of contact is recessed to the central shaft of bearing, when fine dust gets into bearing, owing to have recessed surface of contact; In the zone that the surface of contact that dust all can be deposited in is formed slopely; Thereby can play buffering, retardation for bearing, getting into the inner dust of bearing like this will be very little, thereby guarantees the working life of bearing.
Description of drawings
Fig. 1 is the structural representation of existing bearing.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is the partial enlarged drawing of the said bearing of Fig. 2 at the A place.
Embodiment
Below, technological scheme of the present invention is described further through Figure of description.
Like Fig. 2 and Fig. 3 is the structural representation of bearing of the present invention; Bearing 100 comprises: bearing outer ring 10, the bearing inner race in bearing outer ring 10 20, be fixed on retainer 40 between bearing outer ring 10 and the bearing inner race 20, be fixed on the plurality of balls 30 on the retainer 40 and be set in bearing outer ring 10 and bearing inner race 20 between dust cover 50, dust cover 50 is in order to prevent that dust from getting into the inside of bearing.
Dust cover 50 has first end 51 that matches with bearing outer ring 10 and second end 52 that matches with bearing inner race 20, so that it is inner to prevent that dust from getting into bearing.
Bearing 100 is provided with bearing centre axle X, and this central shaft X is through the center of bearing outer ring 10 with bearing inner race 20, and the setting Y axle vertical with central shaft X.Said bearing inner race 20 has second end, the 52 contacted surface of contact 60 with dust cover 50, and surface of contact 60 is recessed to the bearing centre axle.In other words, the distance of said surface of contact 60 outsides and central shaft X is greater than the distance of said surface of contact 60 inboards with central shaft X.
This surface of contact 60 comprises with central shaft X having first 61 of angle [alpha] and have second 62 of angle beta with the Y axle; Be connected with second 62 for first 61; And angle [alpha] is spent less than 15 greater than 5 degree; And angle [alpha] is preferably 10 degree, and angle beta is spent less than 60 greater than 30 degree, and angle beta is preferably 45 degree.
Consult Fig. 3 simultaneously; When fine dust gets into bearing 100; Owing to have recessed surface of contact 60 with the central shaft of bearing, dust all can be deposited in by in first 61 and second 62 zones of forming 70, thereby can play buffering, retardation for bearing; And getting into the inner dust of bearing will be very little, thereby guarantees the working life of bearing.
