Embodiment 1

[0030] Such as figure 1 As shown, in the embodiment of the present invention, a mechanical transmission runner with adjustable tooth length includes an outer adjustment ring 2 and an inner runner main body 4, and the outer adjustment ring 2 is arranged outside the inner runner main body 4 , in order to ensure the transmission effect and avoid long-term transmission wear and then cause slippage, the outer adjustment ring 2 is equipped with telescopic gear teeth 1 distributed in a circular array. The length limited inside the outer adjustment ring 2 can be adjusted through the fixed pin 3, and then the extension length of the telescopic gear teeth 1 can be adjusted.

[0031] Further, preferably, the telescopic gear teeth 1 are threadedly fixed on the outer adjustment ring 2 through the fixing pin 3. Most of the traditional gear teeth are directly integrally welded on the gear plate, and the telescopic gear teeth 1 and the outer adjustment ring 2 are fixed by using The pin 3 is ...

Embodiment 2

[0034] A mechanical drive wheel with adjustable tooth length, such as Figure 2-4 As shown, the embodiment of the present invention is further limited on the basis of embodiment 1.

[0035] Further, preferably, the outer adjustment ring 2 is equipped with an adjusting cavity 5 distributed in a circular array in conjunction with the telescopic gear teeth 1. The telescopic gear teeth 1 are composed of an extensible gear tooth 14 and a telescopic rod 13. The extensible gear teeth 14 is provided with outer gear teeth 11, the cross section of the outer gear teeth 11 is an isosceles trapezoid, the inner side of the outer gear teeth 11 is fixed with the inner gear teeth 12, the outer gear teeth 11 and the inner gear teeth 12 are integrally fixed, and the inner gear teeth 12 are matched and fixed The pin 3 is provided with the adjusting and fixing holes 15 distributed in an array, and the inside of the adjusting and fixing holes 15 is provided with a screw thread. The lower end is fi...

Embodiment 3

[0037] A mechanical drive wheel with adjustable tooth length, such as Figure 5 As shown, the embodiment of the present invention is further defined on the basis of embodiment 2.

[0038] Further, preferably, in order to realize the expansion and contraction of the telescopic rod 13, the telescopic rod 13 is composed of an inner rod 131 and a sleeve 132, the inner rod 131 is inserted inside the sleeve 132, and the inner rod 131 is fixed in a limited position inside the sleeve 132. Disc 134, the outer surface of limit disc 134 and the inner surface of sleeve pipe 132 are all smooth shape, and the surface of some existing materials is affected by the influence during manufacture, and the problem of surface roughness will inevitably appear, and then can increase friction, and smooth The shape can reduce friction and improve mobility. The lower end of the limit plate 134 is fixed with a second spring 133, and the lower end of the second spring 133 is fixed at the bottom of the sle...

Abstract

The invention relates to a mechanical transmission rotating wheel, in particular to a wheel tooth length-adjustable mechanical transmission rotating wheel. The wheel tooth length-adjustable mechanicaltransmission rotating wheel comprises an outer adjusting ring and an inner rotating wheel main body; the outer adjusting ring is arranged at the external of the inner rotating wheel main body; extension wheel teeth are mounted on the outer adjusting ring in an annular array mode; and the extension wheel teeth are adjusted, limited and fixed through fixed pins. The lengths of the extension wheel teeth in the outer adjusting ring can be adjusted and limited through the fixed pins, so that the extension lengths of the extension wheel teeth are adjusted, the transmission effect is guaranteed, andthe slippage phenomenon caused by long-time transmission wear is prevented; and two fixed pins are provided to improve the limiting stability of the extension wheel teeth, so that the slippage phenomenon easily caused by long-time transmission wear of the wheel teeth with chains or other wheel teeth in a large transmission rotating wheel applying some transmission belts and mechanical conveying equipment in the material conveying field is solved.

Description

technical field [0001] The invention relates to a mechanical transmission runner, in particular to a mechanical transmission runner with adjustable tooth length. Background technique [0002] Affected by the technological progress of machinery manufacturing, electrical machinery, chemical industry and metallurgical industry, the conveyor belt conveyor has been continuously improved, and gradually developed from the completion of the transmission in the workshop to the completion of material handling within the enterprise, between enterprises and even between cities, and has become a material handling An integral part of system mechanization and automation. [0003] Each protruding part on the gear used for meshing, which can mesh with the protruding part on the other wheel to transmit force and motion, is called a gear tooth. Generally, these raised portions are arranged radially. It is used to contact a similar raised portion on a mating gear, thereby causing the gears to...
