Technical Field

The invention belongs to the technical field of bearings, and particularly relates to a cylindrical roller bearing with a gear groove.

Background

The rolling element is cylindrical roller's centripetal rolling bearing, cylindrical roller bearing inner structure adopts the roller to be parallel arrangement, interval retainer or spacer block are equipped with between the roller, can prevent the slope of roller or the looks mutual friction between the roller, the increase of rotary torque has effectively been prevented, current cylindrical roller bearing is in the use, in speed reducer assembling process, need put into the gear groove with the bearing through the hydraulic press, later pack into the speed reducer inner shell the inside, the easy neglected loading spare and accessory retaining ring jump ring of assembling process, crush injury with terminal surface and roller, there is the problem that influences normal use, we propose a cylindrical roller bearing with gear groove for this reason.

Disclosure of Invention

The invention aims to provide a cylindrical roller bearing with a gear groove, and aims to solve the problem that in the use process of the conventional cylindrical roller bearing in the background art, in the assembly process of a speed reducer, the bearing needs to be installed in the gear groove through a hydraulic machine and then installed in an inner shell of the speed reducer, a check ring snap spring of a spare part is easily omitted in the assembly process, and the end face and a roller are crushed, so that the normal use is influenced.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a take cylindrical roller bearing in gear groove, includes the gear groove main part, the inside of gear groove main part is provided with the overcoat, the outside of overcoat is connected with the jump ring, one side of overcoat is connected with the roller main part, the outside of roller main part is connected with the retaining ring, the outside of roller main part is provided with the inner circle, the installation piece is installed in the outside of gear groove main part.

Preferably, the installation piece includes the connecting block, the internally connected of connecting block has first spliced pole, the fixture block is installed to one side of first spliced pole, the internally connected of connecting block has the second spliced pole, the protective housing is installed to one side of second spliced pole, one side inner wall connection of protective housing has connecting spring, connecting spring's opposite side is connected with the fly leaf, the fly leaf is kept away from one side of connecting spring and is installed the fixed column, one side inner wall of protective housing is provided with spacing post, the slider is all installed to the both sides of fly leaf.

Preferably, a through hole for accommodating the limiting column to penetrate is formed in the movable plate, and a sliding groove is formed in the second connecting column.

Preferably, the gear groove main body is internally provided with a connecting groove.

Preferably, the outer sleeve is a polyethylene plastic sleeve.

Preferably, the gear groove body is a planetary gear.

Preferably, the heat treatment mode of the gear groove body is carburizing and quenching.

Compared with the prior art, the invention has the beneficial effects that:

(1) the invention has simple structure, reduces the risk of neglected installation of the retainer ring snap spring, reduces the customer assembly procedures and reduces the condition of crushing damage of the inner ring roller in the assembly process compared with the traditional assembly process after the gear groove and the bearing are assembled by using the play.
