The advantage is design benefit, and the design of the stop pin cooperation on the dust guard of outer lane outside design chute and one side prevents relative rotation between outer lane and the bearing frame, and the inner circle compresses tightly through the backing plate in the axle outside, also effectively prevents relative rotation.

Description

Large-load ball bearing with chute positioning groove

Technical Field

The invention relates to the technical field of bearings, in particular to a heavy-load ball bearing with a chute positioning groove.

Background

At present a lot of bearings are installed and are used at the tip of axle, and the bearing normally designs the inner circle and carries out interference fit with the axle, and the outer lane also is interference fit with the bearing frame, in order to prevent inner circle and axle relative rotation, or relative rotation between outer lane and the bearing frame, can produce the friction like this, and the bearing generates heat to lead to damaging, owing to interference fit when also having some bearing installation, be equipped with the difficulty.

Disclosure of Invention

In order to solve the technical problem, the invention provides a heavy-load ball bearing with a chute positioning groove, which is ingenious in design, convenient to install and capable of effectively preventing relative rotation.

The technical scheme of the invention is as follows:

take heavy load ball bearing of chute constant head tank, it includes outer lane and inner circle, the design has the roller between outer lane and the inner circle, the chamfer department of outer lane opens there is a chute, the inner circle is installed epaxially, the outer lane is then installed in the bearing frame, the tip design of axle has the backing plate, the backing plate passes through screw locking and presses on the outer terminal surface of inner circle at the tip of axle and backing plate a week, installs the dust guard on the outer terminal surface of bearing frame, the dust guard include annular boss, apron, the inboard design of apron has annular boss, the design has the stop pin on the annular boss, annular boss presses on the outer terminal surface of outer lane and the stop pin is inserted in the chute, apron a week passes through the mounting screw on.

The outer ring is in clearance fit with the bearing seat.

The end of the shaft is provided with a step, the inner ring is sleeved on the step, and the width of the inner ring is larger than that of the step.

The inner ring is in clearance fit with the step.

An annular groove is further designed in the bearing seat, a check ring for holes is installed in the annular groove, and the check ring for holes is blocked on the inner end face of the outer ring of the bearing.

The invention has the advantages that the design is ingenious, the chute arranged on the outer side of the outer ring is matched with the stop pin on the dust guard on one side, the relative rotation between the outer ring and the bearing seat is prevented, the inner ring is compressed through the base plate on the outer side of the shaft, and the relative rotation is also effectively prevented.

Detailed Description

Referring to the attached drawings 1-3, a heavy-load ball bearing with a chute positioning groove comprises an outer ring 1 and an inner ring 2, a roller 3 is designed between the outer ring 1 and the inner ring 2, a chute 4 is arranged at a chamfer of the outer ring 1, the inner ring 2 is installed on a shaft 5, the outer ring 1 is installed in a bearing seat 6, a backing plate 7 is designed at the end part of the shaft 5, the backing plate 7 is locked at the end part of the shaft 5 through a screw 71, the backing plate 7 is pressed on the outer end face of the inner ring 2 for a circle, a dust-proof plate 8 is installed on the outer end face of the bearing seat 6, the dust-proof plate 8 comprises an annular boss 81 and a cover plate, an annular boss 81 is designed at the inner side of the cover plate, a stop pin 9 is designed on the annular boss 81, the annular boss 81 is pressed on the outer.

The outer ring 1 is in clearance fit with the bearing seat 6.

The end part of the shaft 5 is provided with a step, the inner ring 2 is sleeved on the step, and the width of the inner ring 2 is larger than that of the step. This design guarantees that the backing plate can play the effect of compressing tightly to the inner circle.

The inner ring 2 is in clearance fit with the step. The step and the backing plate constrain the inner race to the shaft.

An annular groove is further designed in the bearing seat 6, a hole check ring 61 is installed in the annular groove, and the hole check ring 61 is blocked on the inner end face of the outer ring 1 of the bearing. The purpose of the circlip is to restrain the outer race of the bearing within the bearing seat while preventing the retaining pin from disengaging from the chute.

When the anti-rotation bearing is used, the outer ring of the bearing and the bearing seat can be in clearance fit (the clearance fit does not necessarily require that the diameter of the outer ring is much smaller than the inner diameter of the bearing seat and can be the same or smaller by 0-0.05 mm), interference fit is not needed, the installation is very convenient, the bearing can be easily placed into the bearing seat, the invention also designs the chute, the chute is matched with the stop pin designed on the dust cover on one side of the bearing seat, when the dust cover covers the bearing seat from one side, the annular boss supports against the outer ring and positions the stop pin, and therefore the problem that the outer ring rotates in the bearing seat is solved; the inner ring and the step designed on the shaft can also be in clearance fit (the clearance fit is not greatly different), the inner ring can be easily sleeved on the shaft, at the moment, the inner ring is pressed on the shaft by a backing plate, and the backing plate is locked by a screw, so that the device is simple and convenient; the prior fit is interference fit, but the bearing is replaced for several times or the service life is long, and a gap is formed between the bearing and the shaft or the bearing seat, so that friction is generated, and the loss of the bearing is very large. The bearing seat can be a roller or a fixed seat, when the bearing seat is a roller, the shaft and the inner ring of the bearing do not rotate, and the outer ring rotates along with the roller; when the shaft is a fixed seat, the outer ring and the fixed seat do not rotate, and the shaft and the inner ring rotate to work.
