Abstract
The invention discloses a rolling wheel of an elevator landing door system. A metal shaft sleeve is arranged in a through hole, a second arc-shaped annular groove corresponding to a first arc-shaped annular groove is formed in the outer surface of the metal shaft sleeve, and balls are annularly distributed in a chamber formed by the first arc-shaped annular groove and the second arc-shaped annular groove together. The longitudinal part of a metal rolling wheel framework is sleeved with a Teflon outer ring, and one side face of the Teflon outer ring is in blocking connection with the transverse part of the metal rolling wheel framework. The longitudinal part of the metal rolling wheel framework is further sleeved with a metal backup shoe, and the metal backup shoe is located on the other side of the Teflon outer ring and is connected to the end face of the longitudinal part in a fastened manner. The technical aim of reducing the production cost of the rolling wheel of the elevator landing door system is achieved, and the beneficial effects that production cost is relatively low, the limitation of the specification and dimension of the product is small, and meanwhile the service life is long are achieved.
Description
Technical field
The present invention relates to a kind of roller accessory, particularly a kind of roller of elevator landing door system.
Background technology
Elevator roller uses very frequent in whole elevator device, is such as used on the door lock assembly of elevator landing door system.
The roller of 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 standard rolling bearing and roller shaft bearing are riveted.
There is following defect in the roller of the elevator landing door system of said structure: first, and the unit price of standard rolling bearing is relatively high, causes the cost of the roller of whole elevator landing door system relatively high; Secondly, the specification limitation of standard rolling bearing is large, causes the specification of the roller of elevator landing door system to be formulated and there is limitation; Further, the structure design that rubber/plastic outer ring entirety exposes, consider the factor that rubber/plastic outer ring material is relatively soft, it is is easily worn and torn by foreign object.
Therefore, applicant thinks and is necessary to do further structural development to the roller of the elevator landing door system of above-mentioned existing structure.
Summary of the invention
The object of the invention is the roller that a kind of elevator landing door system is provided to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the roller of a kind of elevator landing door system designed by the present invention, comprise Metal Contact Rollers skeleton, the cross section of described Metal Contact Rollers skeleton is in T shape, and longitudinal component is hollow structure, on described longitudinal component with the openings of lateral part homonymy along being provided with the spacing back-up ring extended to the radial direction of through hole, and the inner hole wall of described through hole is provided with the first arc-shaped ring groove, metal axle sleeve is provided with in above-mentioned through hole, the outside face of described metal axle sleeve be provided with the first above-mentioned arc-shaped ring groove relative to the second arc-shaped ring groove, and be furnished with ball in the chamber inner ring that the first arc-shaped ring groove and the second annular annular groove are formed jointly, the longitudinal component of above-mentioned Metal Contact Rollers skeleton is socketed with teflon outer ring, one side of described teflon outer ring and the lateral part of Metal Contact Rollers skeleton keep off and connecing, the longitudinal component of above-mentioned Metal Contact Rollers skeleton is also socketed with metal backup shoe, metal backup shoe is positioned at the opposite side of teflon outer ring, and snapping is on the end face of longitudinal component.
The roller of above-mentioned middle provided a kind of elevator landing door system, without the need to combined standard bearing again in its structure, therefore it manufactures lower relatively, the limitation of the specification of final products is less, and non-metal outer ring is overall built-in between metal backup shoe and the lateral part of Metal Contact Rollers skeleton in its structure, it is is not easily worn and torn by foreign object;
Simultaneously, the direct snapping of above-mentioned metal backup shoe is on the end face of longitudinal component, metal backup shoe and Metal Contact Rollers skeleton is made to be Demountable, consider that non-metal outer ring is vulnerable part, said structure facilitates the replacing of non-metal outer ring, can extend the service life of the roller entirety of elevator landing door system.Its teflon outer ring can possess flameproof effect simultaneously.
The roller of a kind of elevator landing door system that the present invention obtains, the roller of above-mentioned middle provided a kind of elevator landing door system it to have possessed productive costs relatively low, the limitation of product specification size is little, simultaneously the advantage such as long service life.
