Abstract

The utility model relates to a novel self-aligning friction roller of a belt-type conveyor. The novel self-aligning friction roller comprises an end cover (3) and a friction wheel (6) which is connected with the end cover (3), wherein a roller shaft (1) penetrates through the end cover (3) and the friction wheel (6), the inner end of the friction wheel (6) is sequentially provided with a bearing (8) and a shaft sleeve (7), and a noncontact static seal (2) is respectively arranged between the roller shaft (1) and the end cover (3) and between the roller shaft (1) and the shaft sleeve (7). The novel self-aligning friction roller has the advantages that 1) since a key slot on a friction roller shaft and threaded holes inside the friction wheel are canceled, the machining procedures are reduced; 2) since components such as a friction block, a spring, a spring clamping block, a retainer cover and a screw for fixing the retainer cover are removed, the difficulty in installation can be alleviated; 3) since a z-shaped rubber oil seal is used for substituting an original seal felt ring which is arranged between the end cover and the friction roller shaft and between the friction wheel and the shaft sleeve, the sealing effect is enhanced, and the service life of the roller is prolonged.

Description

Novel band conveyer aligning friction roller

Technical field

The utility model relates to belt conveyer field, and concrete is a kind of improvement design of belt conveyer aligning friction roller.

Technical background

Belt conveyer is widely used in the industries such as metallurgy, coal, electric power, building materials, chemical industry, traffic, light industry, and friction aligning carrier roller is one of vitals of belt conveyer, its Main Function is the deviation phenomenon of correcting in time load-transfer device in belt conveyer operational process, prevent from taking not in time to process because of belt deflection, cause load-transfer device and frame frictional tear, leak material, even cause the grave accidents such as ruptured belt and economic loss.

There is following defect in the friction roller of at present general friction aligning carrier roller: 1) complex structural designs, its general felt circle that adopts seals, because felt circle belongs to contact static seal, therefore the friction of itself and roll shaft very easily causes its sealing property to decline, cause roller greatly to reduce service life, in order to improve sealing property, traditional roller increases the parts such as friction shoe, spring in inside, its structure complicated, has increased assembly difficulty and fitting work amount; 2) moreover the mode of traditional fixed type bearing except shaft block ring, it is the mode by adding door and connect by fastener in friction wheel inside, has strengthened assembly difficulty.

Utility model content

The technological deficiencies such as the utility model is to provide a kind of belt conveyer aligning friction roller, and it is mainly the friction roller substructure complexity that solves existing friction aligning carrier roller, and installation difficulty is large, and sealing effectiveness is general, thus reduce production costs and carry the problems such as cost.

The technical solution adopted in the utility model is for this reason: the friction wheel (6) that the utility model comprises end cap (3) and is connected with end cap (3), roll shaft (1) arranges through end cap (3), friction wheel (6), friction wheel (6) the inner sets gradually bearing (8), axle sleeve (7), between roll shaft (1) and end cap (3), establish non-contact type static seal (2) between roll shaft (1) and axle sleeve (7).

Described non-contact type static seal (2) is Z-type rubber oil sea.

Between described friction wheel (6) and roll shaft (1), form the space of settling described bearing (8), the inner end of friction wheel (6) is outside bearing (8), roll shaft (1) is provided with the shaft block ring (4) of fixed type bearing (8), and friction wheel (6) inside face is provided with the back-up ring for hole (5) of fixed type bearing (8).

The utility model has the advantages that: 1), owing to having removed keyway in friction roller axle and the several tapped bore in friction wheel, therefore reduce Liao Ji road manufacturing procedure;

2) owing to removing friction shoe, spring, spring fixture block, door and for parts such as the screws of fixing door, therefore having reduced installation difficulty;

3) owing to replacing the original sealing felt collar for end cap and friction roller axle, friction wheel and shaft room with Z-shaped rubber oil sea, therefore strengthen sealing effectiveness, extended the service life of rod;

4), as above described in 1,2 two, aligning friction roller productive costs has obtained reducing greatly.

Accompanying drawing explanation

Fig. 1 is the structural design drawing of the utility model aligning friction roller.

Fig. 2 is current general friction roller substructure design drawing.

In figure 1 be roll shaft, 2 for non-contact type static seal, 3 for end cap, 4 for shaft block ring, 5 for back-up ring hole for, 6 for friction wheel, 7 be that axle sleeve, 8 is bearing.

The specific embodiment

The utility model adopts the non-contact type static seals 2 such as Z-type rubber oil sea to replace original contact static seal form, in roll shaft 1 rotary course, make between end cap 3 and roll shaft 1, roll shaft 1 and axle sleeve 7 without directly contact, therefore there is not friction, thereby its sealing property can be guaranteed for a long time, improved service life of the present utility model.

The utility model is the inside thickening of friction wheel 6, and it just protrudes bearing 8 and arranges like this, and to mounting hole, with back-up ring 5, provide installing space, thereby traditional door can have been removed, but the utility model reservation shaft block ring 4; By shaft block ring 4 and hole, with both closely cooperate of back-up ring 5, limited moving axially of bearing 8.

The utility model, by structural fine motion, has been removed the structure of conventional roll complexity, and by improving, sealing property further improves, and assembling and maintenance load reduce greatly, have good Practical Performance.
