Abstract

The utility model provides a transmission drum. The transmission drum comprises a drum body and an encapsulation layer covered on the drum body, wherein the encapsulation layer is detachable and is formed by arranging a plurality of arc bodies in the same size in sequence along the peripheral direction, each arc body and the drum body are in a detachable connection structure, saw-toothed protrusions are distributed on the outer surface of each arc body, clamp hooks are distributed on the inner surface of each arc body, clamp grooves which are in the same number as the clamp hooks and are matched with the clamp hooks are distributed on the surface of the drum body, each arc body is connected with the drum body through the clamp hooks and the clamp grooves. According to the transmission drum, the saw-toothed protrusions are designed on the outer surface of the detachable encapsulation layer, the encapsulation layer is matched with a belt in a pressed mode, the friction force between the transmission drum and belt is effectively increased, and the conveying capability of a conveying belt is enhanced. When saw teeth on the surface of the encapsulation layer are worn, the seriously worn saw-toothed surface can be replaced by detaching the encapsulation layer, the operation is simple and the replacement cost is low.

Description

Driving drum

Technical field

The utility model relates to a kind of Drive Drum on Belt Conveyor, particularly a kind of detachable encapsulate driving drum.

Background technology

Belt conveyer is widely used in the conveying of bulk material, and its transmission mainly realizes by the flexible friction between driving drum and the belt.Driving drum and load-transfer device are for improving the mechanical characteristics of Drive Drum on Belt Conveyor, usually coat one deck antifriction rubber layer at the barrel outside face, in order to increase the friction force between driving drum and belt, effectively prevent the cliding friction between cylinder and belt, guarantee that belt is efficient, the running of large conveying quantity, but when the encapsulate serious wear of cylinder, need the dismounting cylinder, re-start encapsulate.The detachable encapsulate layer of at present report research mainly be by bolted to barrel, when encapsulate layer serious wear, need demounting bolt to change, the demounting bolt operation is more loaded down with trivial details.

The utility model content

Technical problem to be solved in the utility model provide a kind of both had increase the effect of rubbing, the Drive Drum on Belt Conveyor of being convenient to again encapsulate layer dismounting and changing.

A kind of driving drum, comprise barrel and the encapsulate layer that is coated on the barrel, this encapsulate layer is detachable encapsulate layer, described encapsulate layer is along the circumferential direction to be arranged successively by the arc body of several formed objects to form, wherein each arc body in axial direction, each arc body and barrel are the detachable connection structure; Described arc body outside face is distributed with jagged projection.

Described arc body inside face is distributed with grab; That the barrel surface distribution has is identical with grab quantity, and the draw-in groove that cooperates with it; Linked together by described grab and draw-in groove between each arc body and the barrel.

The described arc body two ends parallel with axial direction are respectively arranged with a radially grab, and the quantity of this grab and size are all corresponding with draw-in groove.

Two adjacent arc bodies, corresponding two draw-in grooves of its butted part grab separately share a bayonet socket.

Described jagged projection, its protruding tip direction is consistent with the drum rotating direction, can provide enough large friction force during with the work of assurance cylinder, and the stress that reduces simultaneously sawtooth is concentrated, and increases the service life.

The utility model provides a kind of detachable encapsulate layer driving drum, this encapsulate layer is arranged successively along circumferential direction by the arc body of several formed objects and is formed, the arc body outside face is distributed with jagged projection, by with the belt force fit, effectively increase the friction force between driving drum and belt, improve the traffic capacity of load-transfer device; Each arc body inside face is designed with grab, and each arc body and barrel be the detachable connection structure, when the sawtooth of encapsulate layer outside face produces wearing and tearing, can change by dismounting encapsulate layer the serrated-surface of serious wear, and is more convenient to operate.

The specific embodiment

In conjunction with Fig. 1 to Fig. 6, a kind of driving drum comprises driving roller shaft 1, cylinder body surface 2, detachable encapsulate layer 3, zig-zag projection 4, grab 5 and draw-in groove 6.Be coated with detachable encapsulate layer 3 on the cylinder body surface 2, wherein, detachable encapsulate layer 3 is along the circumferential direction to be arranged successively by the arc body of several formed objects to form, each arc body and cylinder body surface 2 are the detachable connection structure, and each arc body outside face is distributed with some jagged protruding 4.

As shown in Figure 4, each arc body inside face is distributed with grab 5, is distributed with draw-in groove 6 identical with above-mentioned grab 5 quantity, that also cooperate with it on the cylinder body surface 2, and each arc body is linked together by grab 5 and draw-in groove 6.

As shown in Figure 6, the arc body two ends parallel with axial direction are respectively arranged with a radially grab, and the quantity of this grab and size are all corresponding with draw-in groove.

As shown in Figure 4, two adjacent arc bodies, corresponding two draw-in grooves of its butted part grab separately share a bayonet socket.

As shown in Figure 2, jagged protruding tip direction is consistent with the direction of drum rotating, can provide enough large friction force during with the work of assurance cylinder, and the stress that reduces simultaneously sawtooth is concentrated, and has prolonged service life.When the sawtooth serious wear on detachable encapsulate layer surface, after only the encapsulate layer need to being taken off, the detachable encapsulate layer that more renews can be finished replacing and the maintenance of cylinder surface.

Need to prove that also under the instruction of this specification sheets, any equivalents or obvious variant that those skilled in the art make the utility model all should be in protection domains of the present utility model.
