Description

TECHNICAL FIELD

[0001] The utility model relates to transmission device technical field, especially in detachable transmission roller group. BACKGROUND

[0002] The composition of the transmission roller differs due to different application scenarios, but the core components thereof can be summarized as the following parts in the design of multiple fields: a roller body, a core component of the transmission roller, usually in a cylindrical shape, which bears the main transmission and support functions. For example, the inner roller of a combined wear-resistant transmission roller for rolling steel, which is quickly disassembled through a threaded rod cooperating with a trapezoidal slide block; a shaft head, a support structure installed at both ends of the roller body, which is connected to the roller body through an annular cavity or a direct cooperation connection part design. The outer end of the shaft head is sleeved with a heat shrink sleeve or a reinforced sealing plate to enhance wear resistance and sealing performance. The roller body, as a force-bearing component, requires a high strength, so the mass of the conventional roller is generally high. Moreover, when conveying some high-temperature components, heat insulation treatment is required. After damage, the entire roller must be replaced, which is very unfavorable for maintenance and disassembly. SUMMARY

[0003] The utility model aims at providing a detachable transmission roller group to solve the problems of the prior art.

[0004] The above technical purpose of the utility model is achieved by the following technical scheme:

[0005] A detachable transmission roller group, comprising a rotating shaft and a sleeve, wherein the rotating shaft is horizontally arranged transversely, the left end of the rotating shaft is sleeved with a disc, the periphery of the disc is provided with a protrusion, the left end of the sleeve is sleeved on the disc, the sleeve is provided with a positioning groove corresponding to the protrusion, the right end of the rotating shaft is provided with a threaded surface, the right end of the rotating shaft is screwed with an end cover, the left end surface of the end cover is attached to the right end surface of the sleeve, the right end of the sleeve is internally provided with a protruding ring, the ring is axially and uniformly provided with left-right penetrating through holes, the end cover is provided with a threaded hole corresponding to the through hole, the threaded hole is screwed with a locking bolt, the left end of the locking bolt penetrates through the end cover and extends into the through hole, and the inside of the sleeve is equally and intervalled provided with a plurality of retaining rings from left to right.

[0006] By adopting the above technical scheme, when the roller structure is damaged by heavy objects rolling on the roller, only the outermost sleeve needs to be replaced, thereby reducing the weight of the roller and the difficulty of maintaining the roller.

[0007] In further embodiments, the retaining ring is made of a porous heat-insulating material.

[0008] By adopting the above technical scheme, when the roller needs to transport some materials with high temperature, the heat will not be conducted to the rotating shaft, thereby ensuring the strength of the rotating shaft.

[0009] In a further embodiment, the two ends of the rotating shaft are provided with spline grooves, and the two ends of the rotating shaft are screwed with pulleys, the pulleys are provided with positioning grooves corresponding to the spline grooves, and the spline grooves are inserted with rectangular blocks.

[0010] By adopting the above technical scheme, the pulley is screwed at the two ends of the rotating shaft, and then the pulley is prevented from rotating after being screwed to the rotating shaft through the cooperation of the spline groove, the positioning groove and the rectangular block, so that the pulley is quickly disassembled and assembled.

[0011] In a further embodiment, the protrusions on the periphery of the disc are arranged symmetrically about the axis of the disc.

[0012] By adopting the above technical scheme, the power is more balanced when the roller rotates.

[0013] In a further embodiment, the surface of the sleeve is provided with anti-skid lines.

[0014] By adopting the above technical scheme, slipping during rotation is avoided.

[0015] In a further embodiment, a plurality of weight-reducing holes are uniformly arranged axially on the disc.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. By setting the roller as a combined structure composed of a rotating shaft and a sleeve, when the roller structure is damaged by a heavy object rolling on the roller, only the outermost sleeve needs to be replaced, which reduces the weight of the roller and the difficulty of maintaining the roller.
