Abstract

The utility model discloses a novel belt type conveyer driving device, wherein a driving roller is sleeved on a roller shaft, and the two ends of the roller shaft are provided with a left bearing seat and a right bearing seat which play supporting functions. One end of a roller close to the right bearing seat is a taper connecting shaft head, a low-speed shaft of a reducer is an internal taper hollow shaft, the taper connecting shaft head and the internal taper hollow shaft can form the taper fit through a key, and the taper fit can be locked through the packing force of the shaft head, thereby realizing the purpose of large torque transmission. The driving device has compact structure and long service life, saves device investment, and has popularization values.

Description

A kind of novel band coveyor drive

Technical field

The utility model relates to a kind of driving device, relates in particular to a kind of colliery scene belt conveyer driving device.

Background technology

Connection structure between belt conveyer and retarder slow-speed shaft normally adopts various coupler, as pin coupler or gear coupling or sprocket wheel coupler or sliding cross coupling, adopt coupler the distance between driving drum and the retarder to be strengthened as attaching parts, when especially under coal mine, using, make flitching, increase and build erected cost.

Summary of the invention

For overcoming the technical matters that prior art exists, the utility model provides a kind of and has not used expensive low-speed shaft coupler, can improve the novel band coveyor drive that transmits mechanical efficiency, loading and unloading and easy to maintenance and long service life.

For achieving the above object, the technical scheme that the utility model adopted is: do not adopt any coupler between the driving drum of described a kind of novel band conveyer and the retarder, but transmit the drum shaft of different moments of torsion and different-diameter according to driving drum, the end machining tapering of the drum shaft that will link to each other with change-speed box becomes tapering and is connected spindle nose, the slow-speed shaft of retarder is processed into the internal taper hollow shaft, it is identical with the tapering of internal taper hollow shaft that tapering connects spindle nose, can formation closely cooperate, and add the key connection.

Adopt a kind of novel band coveyor drive that as above technical scheme provides compared with prior art, technique effect is:

1. reduce the space mounting size, taken up an area of for a short time, be particularly suitable for colliery underworkings operation;

2. without low-speed shaft coupler, saved the equipment investment of coupler, the construction investment in tunnel can reduce 20-30%;

3. loading and unloading, easy to maintenance;

4. compact conformation can prolong 5-10 service life doubly.

Description of drawings

Accompanying drawing is a kind of novel band coveyor drive structural representation described in the utility model, also is Figure of abstract of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing is that the specific embodiment of the present utility model is described in further detail.

As shown in drawings, described a kind of novel band coveyor drive comprise left shaft holder 1 and right bearing seat 1 ', driving drum 2, drum shaft 3, key 4 ', internal taper hollow shaft 5, retarder 6.The two ends that are set with the axis of rolling 3 of driving drum 2 have left shaft holder 1 and right bearing seat 1 ', this is a prior art, near right bearing seat 1 ' one of drum shaft 3 be tapering connection spindle nose 4, on tapering connection spindle nose 4, be processed with keyway, the slow-speed shaft of retarder 6 is an internal taper hollow shaft 5, the tapering of internal taper hollow shaft 5 is identical with the tapering that tapering connects spindle nose 4, be that identical fit dimension is arranged between them, on the internal taper hollow shaft 5 keyway is arranged, tapering connects spindle nose 4, and key 4 ' linking to each other forms taper fitting with using between the internal taper hollow shaft 5.When the internal taper hollow shaft in the retarder 65 rotates, be connected spindle nose 4 through key 4 ' jointly moment of torsion is passed to tapering with the taper fitting face, utilize the thrust of spindle nose to make taper fitting locked, thereby reach the purpose of transmission than high pulling torque.The rotation that tapering connects spindle nose 4 drives drum shaft 3 and driving drum 2 rotations, and the rotation drive of driving drum 2 is transported to next procedure around the belt conveyor action on it with material (as coal).

Claims

1, a kind of novel band coveyor drive, there are left shaft holder (1) and right bearing seat (1 ') in the two ends that are set with the drum shaft (3) of driving drum (2), it is characterized in that: one of the drum shaft (3) of close right bearing seat (1 ') is that tapering connects spindle nose (4), the slow-speed shaft of retarder (6) is internal taper hollow shaft (5), and tapering connects spindle nose (4) with key (4 ') the form taper fitting that links to each other is arranged between the internal taper hollow shaft (5).
