Problems solved by technology

Since the nut in the screw drive structure needs to rotate relatively frequently with the screw, the internal thread on the nut or the external thread on the screw will be worn, and once the nut or the screw is worn, the nut after it is matched There will be a gap between the internal thread on the nut and the external thread on the screw, which will cause loosening during the transmission process of the nut and the screw, which will cause noise and reduce the accuracy of the transmission.

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0023] This embodiment relates to a nut with the function of eliminating gaps. The nut is mainly used in a screw drive structure. During the rotation of the screw 400 , the nut can reciprocate along the axis of the screw 400 . It includes: a first nut body 100 , a second nut body 200 and an elastic member 300 .

[0024] Specifically, one end of the first nut body 100 is provided with a threaded hole 101 for assembling with the screw rod 400 , and the other end is provided with an assembly hole 102 . The thre...

Abstract

The invention discloses a nut with a gap eliminating function, and relates to the technical field of thread transmission. The nut comprises a first nut body, wherein one end of the first nut body is provided with a threaded hole assembled with a lead screw, the other end of the first nut body is provided with an assembly hole, the lead screw is arranged in the assembly hole in a penetrating mode, and the threaded hole communicates with the assembly hole; a second nut body, wherein the second nut body is matched with the lead screw, and the second nut body is assembled on the side, away from the threaded hole, in the assembly hole; and an elastic part arranged on the lead screw in a sleeving mode and located in the assembly hole, wherein one end of the elastic part is assembled with the second nut body, and the other end of the elastic part is assembled with the side, close to the threaded hole, of the inner wall of the assembly hole. The nut is mainly used in a lead screw transmission structure, and the lead screw transmission structure adopting the nut has the beneficial effects of being low in transmission noise, high in transmission precision, high in wear resistance, long in service life, high in bearing capacity and convenient to maintain in the later period.

Description

technical field [0001] The invention relates to the technical field of thread transmission, in particular to a nut with a gap eliminating function. Background technique [0002] A nut is a very common threaded transmission component, usually used in conjunction with a screw as a screw transmission structure. Since the nut in the screw drive structure needs to rotate relatively frequently with the screw, the internal thread on the nut or the external thread on the screw will be worn, and once the nut or the screw is worn, the nut after it is matched There will be a gap between the internal thread on the screw rod and the external thread on the screw rod, so that loosening will occur during the cooperative transmission of the nut and the screw rod, which will generate noise and reduce the accuracy of the transmission. In summary, it is necessary to improve the existing nuts. Contents of the invention [0003] The purpose of the present invention is to aim at the defects an...
