Background

In the casting production, along with the continuous development of automation, in order to improve the production efficiency and reduce the labor cost, more and more automatic equipment is adopted by a casting factory, and a plurality of production lines with different models are designed and produced from manufacturers on the market.

The casting production line is different from a widely-applied conventional production assembly line, a plurality of original pieces cannot be purchased to a proper finished product, different production lines designed by different manufacturers often need different maintenance devices, tools and the like in the actual use process, a storehouse also needs to store spare parts of different models and specifications for use during overhaul or emergency maintenance, and workers use time and labor during maintenance. Meanwhile, a designer also needs to carry out a large amount of work during design, and the design difficulty is increased.

Therefore, in the design and actual use and maintenance processes of the casting production line, similar structures need to be integrated, and similar or similar functional structures are close to each other, so that the production line finally achieves universalization and modularization, and the workload and the design difficulty of the maintenance and repair processes of the casting production line can be greatly reduced.

SUMMERY OF THE UTILITY MODEL

In order to improve the maintenance efficiency of casting production line and accelerate design speed, this application has proposed a casting production line power shaft subassembly.

In order to achieve the purpose, the technical scheme of the application is as follows: a power shaft module of a casting production line comprises a bearing bush, wherein a shaft sleeve, a bearing sleeve, an upper bearing, a lower bearing and a locking nut a are arranged in the bearing bush, a power shaft penetrates through the bearing bush and is sleeved with the lower bearing, the shaft sleeve, the upper bearing, the bearing sleeve and the locking nut a, the shaft sleeve is arranged between the upper bearing and the lower bearing and is used for supporting two outer rings of the bearing, and the bearing sleeve and the locking nut a are sequentially arranged on the upper bearing; the bearing device is characterized in that a bearing seat is connected to the outer wall of the bearing bush, a seat cover is arranged at the bottom of the bearing seat and is in contact with the lower bearing outer ring, an upper cover is arranged at the top of the bearing seat and is connected with the bearing bush, one end of a power shaft penetrates through the seat cover to extend out, the other end of the power shaft penetrates through the upper cover, a synchronous belt pulley and a locking nut b to be in threaded connection, and retaining rings are arranged on the upper portion and the lower portion of two sides of the synchronous belt.

Further, the power shaft is connected with the synchronous belt wheel through a key.

Further, the outer edge of the top of the bearing bush is located between the upper cover and the bearing seat.

Further, the bolt b penetrates through the washer to fasten the upper cover, the outer edge of the top of the bearing bush and the bearing seat.

Further, the bolt a fixes the bottom cover on the bearing seat.

Furthermore, the screw passes through upper portion retaining ring, synchronous pulley, lower part retaining ring, gasket in proper order and is connected with the nut and fasten.

The utility model discloses owing to adopt above technical scheme, can gain following technological effect: according to the power shaft assembly, the power shaft assembly is modularized, is arranged at a synchronous belt power output position of a production line, is of an integrated structure, is integrally provided with spare parts, is integrally replaced, can reduce the number of tools and spare parts in stock used by workers when the workers overhaul and cast the production line on site, can reduce the workload of the workers in the design process, reduces the design difficulty and improves the maintenance efficiency; the module structure has strong universality, and is easy to maintain and replace.
