Abstract

The utility model discloses an elevator roller which comprises a bearing and an outer rubber ring. The elevator roller is characterized in that more than two annular grooves are formed in the surface of an outer ring of the bearing; the outer rubber ring is connected onto the outer ring of the bearing in a sleeving manner; an inner wall of the outer rubber ring is matched with and mutually embedded in the annular grooves; and the elevator roller can be integrally formed in a rubber coating die. The elevator roller provided by the utility model is simple in structure and high in work stability, and can increase economic benefits for an enterprise; and meanwhile, the production processing is simple, the production benefits of the enterprise can be increased, and the technical problems that traditional elevator rollers are poor in structural stability and cumbersome in production processing are solved.

Description

The elevator roller

Technical field

The utility model relates to a kind of elevator components, particularly the elevator roller.

Background technology

The elevator roller uses very frequent in whole elevator device, on the door lock assembly that is used in elevator landing door system.

Present existing elevator roller, its structure probably comprises standard rolling bearing, roller shaft bearing and rubber outer ring, its production technology is as follows: at first with the rubber pressure injection outside the roller shaft bearing, then standard rolling bearing is put into the roller shaft bearing, at last with the riveted joint of standard rolling bearing and roller shaft bearing.

Not only structural stability is poor for above-mentioned elevator roller, and its production technology is also more loaded down with trivial details.

The utility model content

The purpose of this utility model is the elevator roller that a kind of simple in structure, good operating stability is provided in order to solve above-mentioned the deficiencies in the prior art.

To achieve these goals, the elevator roller that the utility model is designed, comprise bearing and rubber outer ring, it is characterized in that being provided with the annular groove that comprises more than two on the surface, outer ring of bearing, rubber outer ring pressure injection is on the outer ring of bearing, and inwall and the annular groove of rubber outer ring are complementary, and mutually embed.

The elevator roller that the utility model provides can be one-body molded in encapsulation die.

As preferably, the described annular groove parallel arrangement that comprises more than two.Above-mentioned preferred version makes the pressure injection occlusal contact area between rubber outer ring and nonstandard bearing increase, and promotes connective stability between the two.

The elevator roller that the utility model obtains, it is simple in structure, and working stability is high, can promote economic interests for enterprise; Simultaneously its production technology is simple, can the enterprise productivity effect, and not only structural stability is poor to have solved existing elevator roller, and also more loaded down with trivial details technical matters of its production technology.
