Abstract
The utility model discloses a double-layer inner ring closely-arranged cylindrical roller bearing which comprises an outer plastic ring, an inner ring and cylindrical rollers. The inner ring comprises an outer-layer inner ring body and an inner-layer inner ring body, the inner-layer inner ring body is located in an inner hole of the outer-layer inner ring body, the cylindrical rollers are closely arranged between the outer circle of the inner-layer inner ring body and the inner hole face of the outer-layer inner ring body, the two ends of the cylindrical rollers in the layer are provided with flat spring locking rings, the peripheries of the flat spring locking rings are inserted into locking grooves of the outer-layer inner ring body, the cylindrical rollers are also closely arranged inside a roller path of the outer-layer inner ring body, and the peripheries of the cylindrical rollers in the layer are covered with the outer plastic ring. According to the double-layer inner ring closely-arranged cylindrical roller bearing, the rotation speed of the bearing is reduced, the loading capacity is improved, the bearing can easily rotate stably, the service life of the bearing is prolonged, and noise is low during operation.
Description
Technical field
The utility model relates to the bearing that a kind of winch and engineering machinery are used, especially a kind of double-deck inner ring solid matter roller bearing.
Background technique
The bearing that winch and engineering machinery are used, some load is large, and rotating speed is high, and bearing rotates uneven steady, and during bearing operation, noise is large, and the working life of bearing is short.
Summary of the invention
The purpose of this utility model is to provide a kind of double-deck inner ring solid matter roller bearing, solves the defect that rotation is steady, noise is large, working life is short that large load roller bearing causes because running up.
The purpose of this utility model realizes as follows: this bilayer inner ring solid matter roller bearing, comprise plastic outer ring, inner ring, cylindrical roller, inner ring has outer inner ring and nexine inner ring, in the endoporus of nexine inner ring in outer inner ring, solid matter cylindrical roller between the cylindrical of nexine inner ring and the inner hole surface of outer inner ring, at the two ends of this layer of cylindrical roller, the flat spring retainer is set, flat spring retainer periphery is inserted in the locked groove of outer inner ring, also solid matter cylindrical roller in outer inner ring raceway, periphery at this layer of cylindrical roller is covered with plastic outer ring, during assembling, plastic outer ring is dismantled.Two inner rings, the use in parallel of double cylindrical roller, can reduce rotating speed, reduces friction factor, improves bearing capacity; Without the retainer structure, reduce the assembling degree of difficulty.
The side face of outer inner ring arranges some oilholes, is convenient to the lubricated of internal layer cylindrical roller.
The utility model has reduced the bearing rotating speed, and load-carrying ability improves, and is easy to the bearing smooth rotation, has improved the working life of bearing, and noise in operating reduces.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
