Abstract
The invention discloses an elevator roller wheel. The section of a metal roller wheel framework is T-shaped. The metal roller wheel framework is of a hollow structure. Limiting stop rings extending in the radial direction of through holes are arranged on the opening edges of the through holes in the same side with a transverse part, on a longitudinal part. A first arc annular groove is formed in the inner hole wall of each through hole, a metal shaft sleeve is arranged in each through hole, a second arc annular groove opposite to the corresponding first arc annular groove is formed in the outer surface of each metal shaft sleeve, and rolling balls are annularly distributed in a cavity formed by each first arc annular groove and the corresponding second arc annular groove. Limiting ribs are annularly distributed on the outer surface of the longitudinal part and parallel to the longitudinal part. A non-metal outer ring is connected to the longitudinal part of the metal roller wheel framework in a sleeving mode, and the limiting ribs are embedded in the non-metal outer ring. A metal gland is connected to the longitudinal part of the metal roller wheel framework in a sleeving mode, and a metal pressing plate, the metal shaft sleeves and the metal roller wheel framework are riveted. The technical purpose that the production cost of the elevator roller wheel is reduced is achieved, and the production cost is low.
Description
Technical field
The present invention relates to a kind of roller accessory, particularly a kind of Elevator roller.
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.
Current existing Elevator roller, 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 Elevator roller of said structure: first, and the unit price of standard rolling bearing is relatively high, causes the cost of whole Elevator roller relatively high; Secondly, the specification limitation of standard rolling bearing is large, causes the specification of Elevator roller 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 Elevator roller of above-mentioned existing structure.
Summary of the invention
The object of the invention is to provide a kind of Elevator roller to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of Elevator roller designed by the present invention, comprise Metal Contact Rollers skeleton and non-metal 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 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, on the outside face of above-mentioned longitudinal component, annular is distributed with limit ribs, all parallel with the longitudinal component distribution of every bar limit ribs, non-metal 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 keeps off and connecing, above-mentioned limit ribs is embedded in non-metal outer ring, 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 non-metal outer ring, above-mentioned metal platen, metal axle sleeve and Metal Contact Rollers skeleton three pass through the port riveted of the longitudinal component of Metal Contact Rollers skeleton.
Above-mentioned middle provided a kind of Elevator roller, 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, and also have the longitudinal component pressed on ring of its Metal Contact Rollers skeleton to be furnished with the limit ribs be embedded in non-metal outer ring, both structural stabilities are good.
A kind of Elevator roller that the present invention obtains, above-mentioned middle provided a kind of Elevator roller it to have possessed productive costs relatively low, the limitation of product specification size is little, simultaneously the advantage such as long service life.
