Description

Tapered roller bearing with outer ring

Technical Field

The utility model relates to a bearing, especially a tapered roller bearing of taking outer lane.

Background

After the existing tapered roller bearing with the outer spacing ring is used for a certain period, the radial movement amount of the retainer relative to the bearing spacing ring and the inner and outer rings is increased due to the objective abrasion of the pocket holes of the retainer, the maximum diameter position of the retainer is interfered with the inner circular surface of the corresponding spacing ring during high-speed operation, the normal operation of the bearing is seriously affected, and the abnormal faults of uneven bearing stress, deformation of the retainer, burning loss of the bearing and the like are just caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a tapered roller bearing of in-band circle that can avoid the interior disc interference of holder and space ring, concrete technical scheme is:

the utility model provides a tapered roller bearing of area outer lane, includes outer lane, inner circle, spacer ring, holder and rolling element, the outer disc symmetry of inner circle is equipped with two raceways, the rolling element rotates to be installed on the holder, and ring array is equipped with a plurality of, the rolling element activity is located in the raceway, the outer lane with the inner circle coaxial line sets up, the outer lane activity is supported on the rolling element, the spacer ring with the inner circle coaxial line sets up, and is located two between the outer lane, the inner disc symmetry of spacer ring is equipped with two and keeps away the position groove, just keep away the position groove with the maximum diameter department of holder sets up relatively.

Preferably, two sides of the avoiding groove incline outwards to form an inverted trapezoid.

Preferably, an oil inlet hole is formed in the space ring, and the oil inlet holes are arranged in an annular array and located in the center of the space ring.

Compared with the prior art the utility model discloses following beneficial effect has:

the utility model provides a pair of tapered roller bearing of in-band circle keeps away the distance between groove increase holder and the spacer through the interior disc setting at the spacer to effectively avoid holder and spacer to take place the problem of interference, guaranteed the normal operation of bearing, prolonged the life of bearing.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, a tapered roller bearing with an outer ring, which includes an outer ring 1, an inner ring 3, a spacer ring 2, a holder 4 and a rolling element 5, wherein two raceways 31 are symmetrically disposed on an outer circumferential surface of the inner ring 3, the rolling element 5 is rotatably mounted on the holder 4, and a plurality of annular arrays are disposed, the rolling element 5 is movably disposed in the raceway 31, the outer ring 1 and the inner ring 3 are coaxially disposed, the outer ring 1 is movably supported on the rolling element 5, the spacer ring 2 and the inner ring 3 are coaxially disposed and are disposed between the two outer rings 1, two clearance grooves 21 are symmetrically disposed on an inner circumferential surface of the spacer ring 2, the clearance grooves 21 are disposed opposite to a maximum diameter of the holder 4, two sides of the clearance grooves 21 are inclined outward to form an inverted trapezoid, that is, and the tapered roller bearing is horn-shaped. The avoiding groove 21 and the maximum diameter position of the space ring 2 are oppositely arranged, namely the avoiding groove 21 and the edge of the space ring 2 are oppositely arranged, two sides of the avoiding groove 21 are respectively oppositely arranged with the outer circular surface and the end surface of the retainer 4, the inverted trapezoidal avoiding groove 21 can increase the width of the avoiding groove 21 and form a larger distance with the outer circular surface and the end surface of the space ring 2, so that the moving space of the retainer 4 can be increased, the influence on the strength of the space ring 2 can be reduced, the interference between the maximum diameter position of the retainer 4 and the space ring 2 can be effectively prevented, and the interference between the outer circular surface and the end surface of the space ring 2 and the space ring 2 can be prevented, so that the retainer 4 does not rub with the space ring 2, abnormal faults such as uneven bearing stress, deformation of the retainer 4, bearing burning loss and the like caused by abrasion interference can be avoided, the bearing can run more smoothly, the service life of the bearing can be prolonged, and the stability and reliability of the bearing running can be improved.

The oil inlet holes 22 are formed in the space ring 2, the oil inlet holes 22 are arranged in an annular array and are located in the center of the space ring 2, the avoiding grooves 21 are symmetrically located on two sides of the oil inlet holes 22, and the oil inlet holes 22 are respectively communicated with the inner circular surface and the outer circular surface of the space ring 2, so that lubricating oil or lubricating grease can be introduced into the bearing to lubricate the rolling elements 5.

The technical principle of the present invention has been described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the claims of the present invention.
