CN2630196Y - Rubber belt conveyer roller - Google Patents

Abstract

A belt conveyer idler consists of a roller body, a shaft, a shaft sleeve, a bearing, a spring collar for hole-use, a spring collar for shaft-use and a dust-proof plate. A bearing outer ring is directly installed on the inner port at both sides of the roller body; an inner ring is matched with the shaft sleeve which is matched with the shaft. Furthermore, the structure is simple, production efficiency is high, manufacture cost is low and service life is long.

Description

A kind of idler of rubber tape conveyor

Technical field

The utility model belongs to field of transport machinery, relates to the slewing arrangement in the travelling apron, particularly a kind ofly in travelling apron adhesive tape is played a supportive role and the carrying roller of transmitting movement.

Background technology

Known idler of rubber tape conveyor is respectively installed a bearing seat at body of roll two ends, and bearing installation is in bearing seat, and outside race cooperates with bearing seat, and inner ring cooperates with axle.The carrying roller of this kind structure is the manufacturing process relative complex not only, production efficiency is lower, cost is higher, and make and to reduce for bearings mounted radial dimension because of being provided with bearing seat, and then the bearing designation that can adopt is little, cause that the loading strength of bearing is low to make its life-span shorter, particularly at a high speed, under the heavily stressed working environment, carrying roller is damaged very soon.

Summary of the invention

In order to overcome traditional carrying roller manufacturing process complexity, the cost height, deficiency such as service life is short, the utility model provides a kind of manufacturing process simple, and cost is low, the carrying roller of long service life.

The technical solution of the utility model is, adopts only smaller than body of roll external diameter big specification bearing, and outside race directly matches with the body of roll, and bearing inner ring is assemblied on the axle sleeve, and axle sleeve is assemblied on the bolster.The carrying roller of this structure is compared with traditional carrying roller, difference is that bearing specification strengthens, replaced heavy cast-iron chock with axle sleeve simple in structure and that size is less, therefore its beneficial effect is, make simple, service life significant prolongation, productive costs is low, particularly under high speed, heavily stressed working environment, show particularly evident.

Description of drawings

Fig. 1 is the cross-sectional schematic of facing of the present utility model;

Fig. 2 is a lateral plan of the present utility model;

Among the figure, the 1st, circlip for shaft; The 2nd, dust guard; The 3rd, circlip for bore; The 4th, bearing; The 5th, axle sleeve; The 6th, axle; The 7th, the body of roll.

The specific embodiment

According to the specification of intending making carrying roller, select the thick-walled seamless steel pipes processing body of roll 7 of respective model for use, also can directly roll the alternate manner processing bodies of roll 7 such as volume with steel plate.Mouth in the two ends of the body of roll process respectively, in the mouth, outside race and lining mouth adopted transition fit in bearing 4 was installed in, and bearing inner ring is installed on the axle sleeve 5, and axle sleeve 5 is installed on the axle 6.For preventing the axial motion of bearing, in body of roll inwall bearing outside one circular groove is set, be used to install circlip for bore 3; For preventing that dust from entering bearing inside and influencing bearing life, be provided with dust guard 2; For the axial location of dust guard, axle is provided with circular groove, is used to install circlip for shaft 1.

The carrying roller two-end structure is just the same, fills with lubricating grease to bearing before the assembling dust guard.

Claims (2)

1, a kind of idler of rubber tape conveyor, comprise the body of roll (7), bearing (4), axle (6) and dust guard (2), it is characterized in that, mouth in the processing of the two ends of the body of roll (7), at the two ends of axle (6) axle sleeve (5) is set respectively, outside race directly cooperates with mouth in the body of roll two ends, and bearing inner ring directly cooperates with axle sleeve (5).

2, a kind of idler of rubber tape conveyor according to claim 1 is characterized in that in the outside of body of roll inwall bearing (4) circlip for bore (3) being set, at the arranged outside circlip for shaft (1) of dust guard (2).
