The inner diameter II of the wheel body 2 is smaller than the outer diameter I of the rolling bearing 1, and the difference range is 1.5mm-5 mm. The utility model discloses an escalator bearing, the wheel body concave structure intermeshing of the protruding structure of rim internal surface and wheel body surface, the rim is difficult for droing.

Description

Escalator bearing

Technical Field

The utility model belongs to the technical field of the gyro wheel structure, concretely relates to high strength escalator bearing.

Background

Along with economic development, more and more public places set up automatic escalator, if at airport, railway station, subway station and market, automatic escalator convenient to use is swift, receives liking of passenger deeply. Because the escalator circularly rotates in a chain type rolling manner, a large number of rollers are needed to be used for supporting rotating parts of the escalator, and because the escalator is generally used in occasions with large passenger flow, the escalator generally rotates continuously and plays an important role as the rollers for ensuring the safe operation of the escalator. Current gyro wheel, its wheel body are wear-resisting material's nylon plastic and make, and the rim is thermoplastic elastic plastic, and the rim cover makes the gyro wheel outside the wheel body, nevertheless because the nylon plastic surface is more smooth, rim and wheel body can produce the phenomenon of skidding, drops very easily during the use.

In the prior art, patent publication No. CN108502690B "a high-strength escalator roller" provides a high-strength escalator roller, which can achieve the purpose of high-strength connection between the roller and the roller shaft by arranging a clamping disc unit, a connecting column unit and an electromagnet unit on the inner ring of the roller. The structure has the defects of complex process, high cost and the like.

Disclosure of Invention

To the not enough of existence among the prior art, the utility model provides a rim is difficult for droing, simple manufacture's staircase bearing. The technical scheme of the utility model as follows:

an escalator bearing which is characterized in that: it comprises rim 3, wheel body 2 and antifriction bearing 1, there is the protruding structure A of at least round rim on the 3 internal surface circumferences of rim, the protruding structure A cross section of rim is rectangle or trapezoidal, have the concave structure of at least round wheel body on the 2 external surface circumferences of wheel body, with the protruding structure A phase-match of rim, 2 internal diameter two of wheel body are less than 1 external diameter one of antifriction bearing.

Above-mentioned staircase bearing, its further characterized in that: the inner diameter II of the wheel body 2 is smaller than the outer diameter I of the rolling bearing 1, and the difference range is 1.5mm-5 mm.

Has the advantages that:

the utility model discloses an escalator bearing, the wheel body concave structure intermeshing of the protruding structure of rim internal surface and wheel body surface, the rim is difficult for droing.
