Abstract

The invention relates to the field of bearings, in particular to a dustproof structure for a roller bearing, which can effectively prevent dust from entering the bearing and also block dust from entering a roller via the gap between a roller shaft and a bearing inner race. The dustproof structure comprises the roller shaft and the bearing, and is characterized in that: the bearing comprises a bearing outer race, bearing balls and the bearing inner race, a dustproof cover is arranged on the outside of the bearing, and covers the bearing outer race, the bearing balls and the bearing inner race, and the part of the dustproof cover, which is in contact with the roller shaft, is of a brush structure.

Description

A kind of roller bearings dustproof construction

Technical field

The present invention relates to field of bearings, be specially a kind of roller bearings dustproof construction.

Background technology

Roller conveyor is commonly used to articles conveyed in workshop; Cylinder in use; Get into drum owing to have dust, thus generally all can cover of dust be installed at the bearing place at cylinder two ends, but between the axle of cylinder and the bearing inner ring slit is arranged; Dust still gets into drum easily from this slit, influence the rotation and the service life of cylinder.

Summary of the invention

In order to address the above problem, the invention provides a kind of roller bearings dustproof construction, it can prevent effectively that dust from getting into from bearing, also can get into drum the slit of blocks dust between drum shaft and bearing inner ring.

Its technical scheme is such: it comprises drum shaft and bearing; It is characterized in that; Said bearing comprises outside race, bearing ball and bearing inner ring; Said bearing arranged outside has cover of dust, and said cover of dust covers said outside race, bearing ball and bearing inner ring, is hair brush structure with said drum shaft contact position on the said cover of dust.

It is further characterized in that said hair brush structure extends a segment distance to said drum shaft direction.

After adopting structure of the present invention; Cover of dust is installed on the bearing outside; Cover of dust covers outside race, bearing ball and bearing inner ring; Can prevent effectively that dust from getting into from bearing, be hair brush structure with the drum shaft contact position on the cover of dust simultaneously, can blocks dust get into drum from the slit between drum shaft and the bearing inner ring.

Description of drawings

Fig. 2 is a cover of dust hairbrush place enlarged diagram among Fig. 1.

The specific embodiment

See Fig. 1, shown in Figure 2, a kind of roller bearings dustproof construction; It comprises drum shaft 1 and bearing 2, and bearing 2 comprises outside race 3, bearing ball 4 and bearing inner ring 5, and cover of dust 6 is installed on bearing 2 outsides; Cover of dust 6 covers outside race 5, bearing ball 4 and bearing inner ring 3; Be hair brush structure 7 with drum shaft 1 contact position on the cover of dust 6, hair brush structure 7 extends a segment distance to drum shaft 1 direction, makes the entering of its further blocks dust.

Claims (2)

1. roller bearings dustproof construction; It comprises drum shaft and bearing; It is characterized in that said bearing comprises outside race, bearing ball and bearing inner ring, said bearing arranged outside has cover of dust; Said cover of dust covers said outside race, bearing ball and bearing inner ring, is hair brush structure with said drum shaft contact position on the said cover of dust.

2. a kind of roller bearings dustproof construction according to claim 1 is characterized in that said hair brush structure extends a segment distance to said drum shaft direction.
