Description

Ejecting device for inner gear ring of gear coupling of scraper conveyor

Technical Field

The utility model relates to a mining scraper conveyor field specifically is to a scraper conveyor gear coupling ring gear ejecting device.

Background

The gear coupling of the scraper conveyor is used between a chain wheel and a speed reducer, has the function of transmitting torque, and consists of two half couplings and an inner gear ring. In recent years, along with the continuous large-scale development of coal mining equipment, the weight of a gear coupling is increased, the installation process is good, mainly during the disassembly and the replacement of a chain wheel, an inner gear sleeve is shifted to separate an inner gear ring from a half coupling to realize the disassembly of the chain wheel, and when the inner gear ring is disassembled, only a crowbar can be adopted due to the influence of space.

Disclosure of Invention

The utility model aims at providing a scraper conveyor gear coupling ring gear ejecting device solves gear coupling because of weight is big, installs a series of problems inconvenient bringing.

In order to solve the above problem, the utility model discloses a technical scheme is: the gear coupling gear ring gear is capable of being shifted to the side of a speed reducer.

Two threaded holes are formed in the rack, the distance between the two threaded holes is 160-180 degrees, the shifting process of the inner gear ring does not deviate from the central line, the threads are close to the inner side of the rack groove, and a bolt is screwed into the counter hole when the inner gear ring is not used.

The utility model has the advantages that: the inner gear ring is shifted by screwing the two lengthened bolts into the threaded holes, so that the operation is convenient, the material cost is reduced, the labor intensity is reduced, and the labor efficiency is improved.

Drawings

The invention will be further described by means of the following figures and examples

FIG. 1 is a front view of the present invention

FIG. 2 is a schematic view of the top view structure of the present invention

1. The device comprises a frame, 2, an inner gear ring of a gear coupling, 3, an ejection bolt, 4 and a chain wheel.

Detailed Description

In fig. 1, two threaded through holes are arranged on a frame 1, the threaded holes are arranged at a certain angle within the range of 160-180 degrees, so that the advantage that the ejection bolt can ensure that the inner gear ring does not deviate from the central axis of the gear ring when pushing the inner gear ring, if the ejection bolt deviates from the central axis, the teeth of the inner gear ring and the teeth of the half coupling are stronger, and finally the inner gear ring is pushed immovably. The counter bores are arranged in the direction close to the inner opening of the groove in the two threaded holes arranged on the rack, the bolts are screwed in, the threaded holes are protected, and the coal and the scraper are prevented from wearing the threaded holes to cause the actual effect of the threaded holes.

In the figure 2, the inner gear ring 2 of the gear coupling, the ejection bolts 3, the chain wheel 4 and the ejection bolts 3 are screwed into threaded holes which are arranged in advance, the two bolts keep synchronous as much as possible in the process of screwing the threaded holes, the inner gear ring of the gear coupling is ensured not to deviate from the central axis in the moving process, the ejection bolts push the inner gear ring of the gear coupling to continuously move towards the speed reducer by continuously rotating the two ejection bolts, finally the inner gear ring of the gear coupling is separated from a half coupling on the chain wheel, the chain wheel can be disassembled, the inner gear ring of the gear coupling is disassembled through the ejection structure, the original condition that the inner gear ring is shifted by a crow bar which is the most original method is changed, the labor intensity is reduced, and the man-machine engineering is embodied.
