Abstract
The invention discloses a conical roller bearing. The conical roller bearing comprises an outer bearing ring and an inner bearing ring. Rollers are arranged between the outer bearing ring and the inner bearing ring and obliquely arranged. Holders are arranged on the left sides and the right sides of the rollers. An oil path is arranged on the inner bearing ring and communicated with the rollers. Semi-circular bosses are arranged on the inner wall of the inner bearing ring. The conical roller bearing has the beneficial effects of being simple in structure, low in cost, safe to use, high in load resisting capacity and fatigue resisting capacity, long in service life and the like; due to the fact that generatrices of the rollers are designed through an arc curve, the convexity of a roller path of the inner bearing ring and the outer bearing ring and the roller basal plane shape design are improved, the convexity of the roller path and the rollers is reasonably configured, the diameter of a flange is increased, and the acting point of the bearing in the static state serves as the top point of a convex face; during high-speed composite running, the bearing is evenly stressed, and the friction torque of the bearing is effectively lowered; and therefore corner abrasion is reduced, the service life of the bearing is prolonged, and premature aging of the bearing is avoided.
Description
Technical field
The present invention relates to power tool accessory field, particularly a kind of tapered roller bearing.
Background technique
Bearing (Bearing) is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two.Wherein rolling bearing standardization, seriation, but its radial dimension, vibration & noise is comparatively large compared with sliding bearing, and price is also higher.Rolling bearing is generally made up of outer ring, inner ring, rolling element and retainer four part, is made up of strictly speaking outer ring, inner ring, rolling element, retainer, sealing, the large part of lubricant oil six.Mainly possess outer ring, inner ring, rolling element and just surely can mean rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and the large class of roller bearing two.
And well-known, for a long time, domestic bearing, after certain stroke of passing through, needs to adjust axial clearance, and the bearing of import in use between on longer more of a specified duration.Although the carrying of this class bearing is comparatively large, processing is simple, and under meeting running at a high speed, wearing and tearing easily appear in roller two ends diameter parts, and cause bearing premature aging, working life reduces greatly.
Summary of the invention
The object of this invention is to provide a kind of rigidity by strong, that withstand load ability is comparatively strong, fatigue resistance is comparatively strong, working life is longer a kind of tapered roller bearing.
The technical solution used in the present invention is:
A kind of tapered roller bearing, comprise bearing outer ring and bearing inner race, its innovative point is: be provided with roller between described bearing outer ring and bearing inner race, described roller is for being obliquely installed, the left and right sides of described roller is provided with retainer, described bearing inner race is provided with oil duct, and described oil duct communicates with described roller, and the inwall of described bearing inner race is provided with semicircle boss.
Further, the angle of described ball bank is 30 ° ~ 40 °.
Further, described boss is located at the right side of described oil duct.
Further, the circular runout of described bearing bore diameter is 8, and it is 10 that outer radial is beated.
Beneficial effect of the present invention is as follows:
It is simple that the present invention has structure, cost is lower, use safety, good airproof performance, rigidity will be strong, withstand load ability is stronger, fatigue resistance is stronger, the advantages such as working life is longer, owing to adopting the bus of arc curve design roller, in improvement bearing, outer ring raceway convexity and roller basal plane profile design, reasonable disposition raceway and profiled rollers, strengthen rib diameter, Point of Strength when making bearing static is convex surface summit, when meeting running at a high speed, bearing is made to reach uniform force, effective reduction bearing frictional torque, thus decrease the wearing and tearing of corner, extend the working life of bearing, avoid bearing early ageing phenomenon.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of tapered roller bearing as shown in Figure 1, comprise bearing outer ring 1 and bearing inner race 2, roller 3 is provided with between described bearing outer ring 1 and bearing inner race 2, described 3 sons that roll are for being obliquely installed, the left and right sides of described roller 3 is provided with retainer 4, described bearing inner race 2 is provided with oil duct 5, and described oil duct 5 communicates with described roller 3, and the inwall of described bearing inner race 2 is provided with semicircle boss 6.
Working principle of the present invention is:
In use, to improve in bearing 2, outer ring 1 track convex degree and roller 3 basal plane profile design, reasonable disposition raceway and roller 3 convexity, strengthen rib diameter, and Point of Strength when making bearing static is convex surface summit, when meeting running at a high speed, make bearing reach uniform force, effectively reduce bearing frictional torque, thus decrease the wearing and tearing of corner, extend the working life of bearing, avoid bearing early ageing phenomenon.
The above is the preferred embodiment of the present invention, can not limit the interest field of the present invention with this.It should be pointed out that for those skilled in the art, technological scheme of the present invention is modified or equivalent replacement, do not depart from protection scope of the present invention.
Claims (4)
