Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings.

[0020] Such as Figure 1 to Figure 3 As shown, the isocentric rotation system of the mammography machine in this embodiment includes: a power element 1 and a transmission assembly connected with the power element 1. Power element 1 In this embodiment, a motor is used for description. The transmission assembly is connected with the C-shaped arm 4 to drive the C-shaped arm 4 to rotate. The transmission assembly includes a toroidal worm gear 2. The toroidal worm gear 2 includes a worm wheel 20 and a worm 21.

[0021] The transmission assembly further includes a belt transmission device 3. The power element 1 transmits the power to the toroidal worm gear 2 through the belt transmission device 3. The belt transmission device 3 adopts a synchronous belt transmission in this embodiment, and includes a first belt wheel 30, a second belt wheel 31, and a synchronous belt 32. In this embodim...

Abstract

The invention relates to an isocentric rotating system of a mammary gland X-ray machine, comprising a power element and a transmission assembly, wherein the transmission assembly is connected with thepower element and a C-shaped arm and comprises a ring-surface screw gearing, and the ring-surface screw gearing is connected with the C-shaped arm, drives the C-shaped arm to act and comprises a wormand a worm wheel; the ring-surface screw gearing is used for driving the C-shaped arm to act so that the transmission assembly is in multi-teeth meshing transmission so as to achieve steady transmission, very low noise, a large number of contracted teeth during the transmission, larger contact surfaces of tooth surfaces, instantaneous double-wire contact, long total length of a contact wire, longcomprehensive curvature radius, little contact stress, large meshing lubrication angle, easy dynamic pressure oil film forming during meshing and tooth surface abrasion reduction; an equivalent weight curvature radius is long, thus the transmission efficiency is higher, and the carrying capacity is high; and besides, the ring-surface screw gearing has a self-locking function so as to play safetyand protection roles and realize the accurate positioning of the C-shaped arm at different positions.

Description

【Technical Field】 [0001] The invention relates to a mammary gland X-ray machine, in particular to a mammary gland X-ray machine isocentric rotation system. 【Background technique】 [0002] In a traditional mammography machine, the isocentric rotation system of the mammography machine connected to the C-shaped arm adopts the sprocket transmission assembly and the C-shaped arm transmission connection to realize the C-shaped arm rotation function, which requires the chain to have high dimensional accuracy and good strength. , And the transmission stability of the sprocket is poor. At the same time, multiple chains must be used to ensure the safety of transmission, and a tensioning device must be added to ensure the tension of the chain. At the same time, there is a risk of chain breakage. [Content of the invention] [0003] Based on this, it is necessary to provide an isocentric rotation system for mammography with better transmission stability. [0004] A mammography X-ray machine is...
