Abstract
The invention discloses an elevator hanging gear. The section of a metal idler wheel framework is in a T shape, and the longitudinal part of the metal idler wheel framework is of a hollow structure. The opening edge of a through hole, in the same side of a transverse part, of the longitudinal part is provided with a limiting check ring extending towards the radial direction of the through hole. A first arc annular groove is formed in the inner hole wall of the through hole. A metal shaft sleeve is arranged inside the through hole. A second arc annular groove opposite to the first arc annular groove is formed in the outer surface of the metal shaft sleeve. Balls are annularly distributed in a cavity formed by the first arc annular groove and the second arc annular groove. The longitudinal part of the metal idler wheel framework is sleeved with a non-metal outer ring, one lateral face of the non-metal outer ring and the transverse part of the metal idler wheel framework are in blocked connection, the longitudinal part of the metal idler wheel framework is further sleeved with a metal gland, and the metal gland is located on the other side of the non-metal outer ring and buckled on the end face of the longitudinal part. The technical purpose of reducing the production cost of the elevator hanging gear 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 change gear.
Background technique
Elevator change gear uses very frequent in whole elevator system, is such as used on the door lock assembly of elevator landing door system.
Current existing elevator change gear, 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 change gear of said structure: first, and the unit price of standard rolling bearing is relatively high, causes the cost of whole elevator change gear relatively high; Secondly, the specification narrow limitation of standard rolling bearing is large, causes the specification of elevator change gear to be formulated and there is narrow limitation; Further, the structural 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, claimant thinks and is necessary that the elevator change gear to above-mentioned existing structure does further architecture advances.
Summary of the invention
The object of the invention is to provide a kind of elevator change gear to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of elevator change gear designed by 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 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 outer surface 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, 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 keeps 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 nonmetal outer ring, and snapping is on the end face of longitudinal component.
Above-mentioned middle provided a kind of elevator change gear, without the need to combined standard bearing again in its structure, therefore it manufactures lower relatively, the narrow limitation of the specification of final products is less, and nonmetal 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, on the end face of longitudinal component, makes metal backup shoe and Metal Contact Rollers skeleton be Demountable, considers that nonmetal outer ring is vulnerable part, said structure facilitates the replacing of nonmetal outer ring, can extend the working life of elevator change gear entirety.
A kind of elevator change gear that the present invention obtains, above-mentioned middle provided a kind of elevator change gear it to have possessed cost of production relatively low, the narrow limitation of product specification size is little, simultaneously the advantage such as long service life.
