Abstract
The invention discloses a hanging wheel in an elevator landing door system. The section of a metal rolling wheel framework is in a T shape, the metal rolling wheel framework is of a hollow structure, the orifice edge of a through hole formed in the portion, on the same side as a transverse part, on a longitudinal part is provided with a limit check ring extending in the radial direction of the through hole, the inner hole wall of the through hole is provided with a first arc-shaped ring groove, a metal shaft sleeve is arranged in the through hole, the outer surface of the metal shaft sleeve is provided with a second arc-shaped ring groove opposite to the first arc-shaped ring groove, roll balls are annually distributed in a chamber jointly formed by the first arc-shaped ring groove and the second arc-shaped ring groove, and notches are uniformly distributed on the surface of a spherical body of each roll ball; a non-metal outer ring is connected to the longitudinal part of the metal rolling wheel framework in a sleeving mode, one side face of the non-metal outer ring is connected with the transverse part of the metal rolling wheel framework in a blocking mode, the longitudinal part of the metal rolling wheel framework is connected with a metal gland in a sleeved mode, and the metal gland is connected to the end face of the longitudinal part in a covering mode. According to the hanging wheel, the technical problem of the production cost of the hanging wheel in the elevator landing door system is solved, and the production cost is low.
Description
Technical field
The present invention relates to the change gear in a kind of roller accessory, particularly a kind of elevator landing door system.
Background technology
Elevator roller uses very frequent in whole elevator device, such as being used on the door lock assembly of elevator landing door system.
Change gear in current existing elevator landing door system, its structure probably comprises standard rolling bearing, roller shaft bearing and rubber/plastic outer ring, its production technology is as follows: first by rubber/plastic outer ring pressure injection outside roller shaft bearing, be generally the structure that rubber/plastic outer ring entirety exposes, then standard rolling bearing is put into roller shaft bearing, finally by standard rolling bearing and the riveted joint of roller shaft bearing.
There is following defect in the change gear in the elevator landing door system of said structure: first, the unit price of standard rolling bearing is relatively high, causes the cost of the change gear in whole elevator landing door system relatively high; Secondly, the specification limitation of standard rolling bearing is large, causes the specification formulation of the change gear in elevator landing door system to have limitation; Further, the structural design that rubber/plastic outer ring entirety exposes, considers the relatively soft factor of rubber/plastic outer ring material, and it is is easily worn and torn by foreign object.
Therefore, applicant thinks and is necessary the change gear in the elevator landing door system of above-mentioned existing structure to do further architecture advances.
Summary of the invention
The object of the invention is provides the change gear in a kind of elevator landing door system in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, change gear in the designed a kind of elevator landing door system of the present invention, comprise Metal Contact Rollers skeleton and nonmetal outer ring, the cross section of described Metal Contact Rollers skeleton is in T shape, and longitudinal component is hollow structure, on described longitudinal component, be provided with the spacing back-up ring radially extending to through hole with the openings edge of lateral part homonymy, and the inner hole wall of described through hole is provided with the first arc-shaped ring groove, in above-mentioned through hole, be provided with metal axle sleeve, the outer surface of described metal axle sleeve be provided with the first above-mentioned arc-shaped ring groove with respect to the second arc-shaped ring groove, and ball has been periphery in the first arc-shaped ring groove and the common chamber forming of the second annular annular groove, on the spherome surface of each ball, be evenly equipped with recess, nonmetal outer ring sleeve is connected on the longitudinal component of Metal Contact Rollers skeleton, and the lateral part of a side and Metal Contact Rollers skeleton gear connects, on the longitudinal component of above-mentioned Metal Contact Rollers skeleton, be also socketed with metal backup shoe, metal backup shoe is positioned at the opposite side of nonmetal outer ring, and snapping is to the end face of longitudinal component.
Change gear in above-mentioned middle provided a kind of elevator landing door system, in its structure without combined standard bearing again, therefore it manufactures lower relatively, the limitation of the specification of final products is less, and nonmetal outer ring entirety is built-in between metal backup shoe and the lateral part of Metal Contact Rollers skeleton in its structure, it is difficult for being worn and torn by foreign object. The lip-deep recess of above-mentioned ball can also be stored lubricant simultaneously.
Change gear in a kind of elevator landing door system that the present invention obtains, the change gear in above-mentioned middle provided a kind of elevator landing door system it to have possessed production cost relatively low, the limitation of product specification size is little, simultaneously the advantage such as long service life.
