Description

Bearing structure of rotary kiln riding wheel

Technical Field

The utility model relates to a bearing technical field, concretely relates to rotary kiln riding wheel bearing structure.

Background

The riding wheel device of the rotary kiln bears the weight of the whole rotary part; and the rotary kiln cylinder body and the rolling ring can stably rotate on the riding wheel. The rotary kiln during operation, the load of riding wheel can reach hundreds of tons, and the rotary kiln not only will guarantee that the bearing frame has sufficient bearing capacity at the operation in-process, but also will make the bearing frame durable and the atress even, just so, the utility model provides a rotary kiln riding wheel bearing structure.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rotary kiln riding wheel bearing structure to increase the lifting surface area increase of radial force on the bearing frame and make power evenly distributed, improved the durability of bearing frame.

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

the rotary kiln riding wheel bearing structure comprises two bearing bodies, wherein riding wheel shafts are rotatably arranged in the bearing bodies, the upper parts of the two riding wheel shafts are used for supporting a rotary kiln cylinder body, each bearing body comprises a bearing seat, a bearing and a bearing cover, the end surface of each bearing seat is an inclined surface, the bearing is arranged on each bearing seat, the bearing covers are covered on the bearing seats, a first included angle b is formed between the covering contact surface of each bearing cover and the corresponding bearing seat and the horizontal plane, a second included angle a is formed between the centers of the two bearings and the central connecting line of the rotary kiln cylinder body, the second included angle a is 60 degrees, and the first included angle b is 30 degrees.

Furthermore, the bearing seat is fixedly arranged on the supporting beam.

Furthermore, a riding wheel shaft is arranged in the bearing, a riding wheel is arranged on the riding wheel shaft, and the diameter of the riding wheel is larger than that of the riding wheel shaft.

Furthermore, a wheel belt is fixedly arranged on the periphery of the rotary kiln barrel and is in contact with the supporting wheel.

Furthermore, the bearing seat is connected with the bearing cover through screws, and the bearing is a rolling bearing.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses the 30 contained angles of well bearing frame and bearing cap faying face and horizontal direction one-tenth, the rotary kiln during operation, the center of bearing becomes 60 contained angles with rotary kiln barrel center, and the area of stress of radial force increases on the design messenger bearing frame like this, and the radial force that receives on the bearing cap reduces greatly, has guaranteed the durability of bearing frame. The contact area of the supporting roller bearing and the bearing seat in the stress direction is increased, so that the stress is more easily and uniformly distributed, and the phenomenon that the normal operation of the rotary kiln is influenced due to damage caused by overlarge local stress of the supporting roller bearing is avoided.
