Abstract

The utility model provides a speed reducer protection device of a disc pelletizer, which comprises a pinion, a speed reducer, a bearing seat, a transmission shaft and a shaft coupling, wherein the bearing seat is fixed on a main shaft box of the disc pelletizer, bearings are respectively arranged at two ends of the bearing seat, and sealing end covers are respectively arranged on the outer end faces at two ends of the bearing seat; a transmission shaft is arranged in the bearing seat, a small gear is installed at one end of the transmission shaft, and the other end of the transmission shaft is connected with a shaft of the speed reducer through a coupler. The utility model discloses a transmission shaft and shaft coupling have realized that the pinion drives the axle operation of speed reducer under the gear wheel drive, have avoided pinion lug connection speed reducer, will exert oneself and transmit the transmission shaft on, have protected the speed reducer, have prolonged the life of speed reducer.

Description

Speed reducer protector for disc pelletizer

Technical Field

The utility model relates to the field of mechanical equipment, particularly, relate to a speed reducer protection device of balling disc.

Background

The disc pelletizer is used in the steel industry and is a device for manufacturing green pellets in a pellet production process; during production, the disc pelletizer needs to continuously work, and the working environment is severe, so that the disc pelletizer and main parts thereof are required to be reasonable, simple and reliable in structure and convenient to maintain.

The pinion of the disc pelletizer is arranged on the shaft of the speed reducer, and the pinion is directly connected with the shaft of the speed reducer, so that the speed reducer of the disc pelletizer is subjected to overlarge stress to cause abrasion, the service life of the speed reducer is greatly shortened, and the daily maintenance cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a speed reducer protection device for a disc pelletizer, which can well protect a pinion and a speed reducer of the disc pelletizer and prolong the service life of the disc pelletizer.

In order to solve the above problem, the utility model adopts the following technical scheme:

a speed reducer protection device for a disc pelletizer comprises a pinion, a speed reducer, a bearing seat, a transmission shaft and a coupling, wherein the bearing seat is fixed on a main shaft box of the disc pelletizer; a transmission shaft is arranged in the bearing seat, a small gear is installed at one end of the transmission shaft, and the other end of the transmission shaft is connected with a shaft of the speed reducer through a coupler.

Compared with the prior art, the utility model discloses an installation method's advantage lies in:

one end of the transmission shaft is connected with the pinion, and the other end of the transmission shaft is connected with the shaft of the speed reducer through the coupler, so that the pinion drives the shaft of the speed reducer to run under the driving of the gear wheel, the pinion is prevented from being directly connected with the speed reducer, force is transmitted to the transmission shaft, the speed reducer is protected, and the service life of the speed reducer is prolonged.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

description of reference numerals:

a pinion 1; sealing the end cover 2; a bearing 3; a bearing seat 4; a transmission shaft 5; a coupler 6; and a speed reducer 7.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.

Referring to fig. 1, a speed reducer protection device for a disc pelletizer is shown, which is composed of a pinion 1, a bearing seat 4, a transmission shaft 5, a coupler 6, a speed reducer 7 and the like. A transmission shaft 5 is installed in the bearing seat 4, bearings 3 connected with the transmission shaft 5 are respectively arranged at two ends of the bearing seat 4, and sealing end covers 2 are respectively arranged on the outer end faces of the bearing seat 4. The bottom of the bearing seat 4 is provided with a fixing hole and is fixed on a main shaft box of the disc pelletizer through the fixing hole, so that the stability of the whole protection device is maintained. One end of the transmission shaft 5 is provided with a pinion 1, the other end of the transmission shaft is connected with a speed reducer 7 through a coupler 6, and the pinion 1 is connected with a large gear of the disc pelletizer.

The working process of the utility model is as follows:

become indirect connection through the lug connection of transmission shaft 5 and shaft coupling 6 with pinion 1 and speed reducer 7's axle, thereby the drive transmission shaft 5 rotates with gear wheel connection's pinion 1 during the operation of the disc pelletizer, the axle that drives shaft coupling 6 drive speed reducer 7 rotates, the normal operating of speed reducer has been realized, the axle lug connection of pinion 1 and speed reducer 7 has been avoided again simultaneously, transmit transmission shaft 5 with the power that the operation in-process produced, after transmission shaft 5 wearing and tearing, it can to change the transmission shaft, well guard action has been played to speed reducer 7, speed reducer life has been prolonged.

The above description is only the preferred embodiment of the present invention. Various modifications and equivalent changes may be made by those skilled in the art without departing from the spirit and scope of the present invention, and such modifications and changes are intended to be included within the scope of the present invention.

Claims
