Abstract
The utility model relates to a band conveyor bend pulley which comprises a shaft, an outer cylinder body, a bearing, a bearing seat, a bearing cover, rotary seals and bolts. A rotary seal I is arranged between the bearing cover and the shaft, and an oil cup is arranged on the end portion of the shaft. The band conveyor bend pulley is characterized in that a rotary seal II is arranged between the bearing cover and the bearing seat, an O-shaped sealing ring is arranged between the bearing seat and the shaft, and the bearing cover and the bearing seat are fixed on the inner wall of the outer cylinder body through the bolts.
Description
Affiliated technical field
The utility model relates to the ribbon conveyer bend pulley, is specially a kind of ribbon conveyer bend pulley.
Background technology
Traditional ribbon conveyer bend pulley as depicted in figs. 1 and 2, bearing cap shim 6 is connected on outer cylinder body 5 inwalls by bolt 4 with bearing seat 7, bearing 8 closely cooperates with bearing seat 7, injects greases by the hole on axle 2 to bearing 8 and realizes bearing lubrication; Bearing cap shim is equipped with the rotary seal 3 that a forward is installed, and plays the effect that prevents that grease from outwards overflowing; Bearing seat 7 is not installed any sealing member.In the larger transportation occasion of the inferior dust of coal mine, long-term use can cause a large amount of dust to enter into bearing 8 from the plane of revolution of rotary seal 3, causes bearing failure to lose efficacy, and affects work efficiency.In addition, in bearing bore, a part of grease also can overflow from the fitting surface of bolt joint face or bearing seat and axle, causes the waste of grease.
At present, solve the technical matters that above defective those skilled in the art should capture.
The utility model content
The purpose of this utility model is: the use problem for traditional ribbon conveyer bend pulley exists provides a kind of new ribbon conveyer bend pulley.
The purpose of this utility model is achieved in that a kind of ribbon conveyer bend pulley, comprise axle, outer cylinder body, bearing, bearing seat, bearing cap shim, rotary seal and bolt, be provided with the rotary seal I between bearing cap shim and axle, the end of axle is provided with the grease lubricating cup, it is characterized in that: be provided with the rotary seal II between bearing cap shim and bearing seat, be provided with O-ring seals between bearing seat and axle, bearing cap shim and bearing seat are bolted on the outer cylinder body inwall.
In the technical solution of the utility model: the rotary seal I between bearing cap shim and bearing seat is a pair of rotary seal that forward is installed and oppositely installed.
In the technical solution of the utility model: the rotary seal II between bearing cap shim and bearing seat is the rotary seal that a forward is installed.
The utility model has the advantage of: because bearing cap shim is equipped with a pair of rotary seal that a forward one is oppositely installed, play the two way seal effect, outside dust can not enter into bearing, grease in bearing bore can not outflow yet and spill into outside cylinder, strengthens bearing service life and saves grease; The bearing seat forward is equipped with a rotary seal, and the bearing seat periphery is equipped with O-ring seals, can prevent that grease in bearing bore from outwards overflowing outflow by the fitting surface place of bolt joint face or bearing seat and axle, causes the waste of grease.
