Supporting device of rolling wheel of rotary rack of radiation oncology equipment

Abstract

The invention belongs to the field of radiation oncology equipment, and discloses a supporting device of rolling wheels of a rotary rack of radiation oncology equipment. The supporting device of the rolling wheels of the rotary rack of the radiation oncology equipment comprises a supporting base and a bearing wheel supporting assembly, the bearing wheel supporting assembly comprises a supporting box body and a tapered bearing wheel rolling path assembly which is arranged on the supporting box body, the tapered bearing wheel rolling path assembly comprises two sets of tapered bearing wheel supporting units, and each set of tapered bearing wheel supporting units comprises a bearing wheel shaft, a tapered bearing wheel, a bearing wheel end cover and a box body end cover. According to the supporting device of the rolling wheels of the rotary rack of the radiation oncology equipment, the mounting difficulty of the bearing wheel shafts can be lowered by utilizing the two bearing wheel shafts to support a tapered bearing shaft; meanwhile, the two tapered bearing wheels are utilized and each tapered bearing wheel is internally provided with a self-aligning bearing, and the self-aligning function can be achieved in the mounting process; in addition, axial limitation of the rotary rack can be achieved by utilizing the tapered bearing wheels, the self-aligning bearing can only bear the radial force through force transmission, the axial force is borne by a self-aligning thrust roller bearing, and accordingly the life of the self-aligning bearing can be prolonged.

Description

technical field [0001] The invention belongs to the field of radiotherapy equipment, and more specifically relates to a support device for a rotating frame roller of radiotherapy equipment. Background technique [0002] In the field of radiotherapy equipment, large mass and large inertia are the difficulties that need to be considered in the design process. Especially in the process of on-site installation, due to the large mass, once the main part is installed on the support part, it is difficult to make adjustments. However, due to the inevitable installation deviation, it will affect the coaxiality and position accuracy of the overall equipment. Therefore, a support device with a certain degree of self-positioning adjustment function is an indispensable means to solve this problem and improve the installation accuracy. Fine-tuning itself through the ingenious structure and its own geometric principles can not only reduce the difficulty of debugging during the installati...

Problems solved by technology

This has certain potential safety hazards for a large-scale equipment that operates for a long time and requires a long life

[0004] Therefore, according to the existing support form, there are some problems: 1) the self-aligning function of the self-aligning bearing cannot be exerted; 2) the axial limit cannot be achieved by itself; 3) the on-site installation efficiency is improved and the difficulty of installation and debugging is reduced ;4) Due to the high safety requirements of the equipment, the long service life and the difficulty of replacing the bearings, it is necessary to ensure the service life of the bearings, thereby ensuring the service life of the equipment
