Problems solved by technology

Adding too much grease will definitely cause a large amount of steel grit to adhere to the surface of the screw and be brought into the nut, causing the screw nut to bite; without adding grease, the screw nut will be in a non-lubricated working state for a long time, which will aggravate the wear of the nut and affect the To the positioning accuracy of the roller table

Embodiment

[0023] A solid lubricating device for open screw nut transmission of CNC machine tools, its structure is as follows Figure 1~3 As shown, the device is used for surface lubrication of open screw rods, including a nut 1 and a nut seat 4, the nut 1 is fixed on the inside of the nut seat 4, and the connection between the interior of the nut seat 4 and the nut 1 is provided for placing a solid lubricant The hollow inner cavity 2 of the nut 1 communicates with the inner cavity of the nut 1 through the powder passage 41 . Wherein, the local enlargement figure of powder passage 41 is as follows: image 3 As shown, the powder channel 41 is set at the tooth root of the nut 1. The front end of the powder channel 41 is funnel-shaped, and a circular ball 3 is stuck at the port of the powder channel 41. The push rod 42 used to prevent the round ball 3 from falling back. The nut seat 4 is provided with a gland 5 for sealing the hollow cavity 2, and the gland 5 and the nut seat 4 are conne...

Abstract

The invention relates to a solid lubricating device used for open-type lead screw nut transmission of a numerical control machine tool. The solid lubricating device is used for lubricating the surface of an open-type lead screw and comprises a nut and a nut seat. The nut is fixed to the nut seat, a hollow inner cavity used for storing solid lubricating agents is formed inside the nut seat and communicates with an inner cavity of the nut through a powder channel, and a circular ball is arranged in a connecting channel. Compared with the prior art, the solid lubricating agents are adopted as lubricating materials, so that friction and abrasion of the two surfaces making relative movement are reduced, and the surfaces are protected against being damaged, the situation that grease is used for lubricating is avoided, so that the overflowing grease is avoided, and not only is the steel grit erosion degree reduced, but also the working environment is improved.

Description

technical field [0001] The invention relates to the field of screw lubricating, in particular to a solid lubricating device for driving an open screw nut of a numerically controlled machine tool. Background technique [0002] Screw transmission is a mechanical transmission that transmits power and motion by the engagement of the screw and the nut. It is mainly used to convert rotary motion into linear motion and torque into thrust. Screw drive, that is, screw nut drive, is the same as gear drive, with open, semi-open and closed drives. When the screw nut drive has no dust cover or casing, and the screw rod is completely exposed to the outside, it is called an open drive; when the screw nut drive is equipped with a protective cover, it is called a semi-open drive. [0003] Under normal circumstances, in order to achieve good lubrication, it is necessary to add too much lubricating grease, and if too much lubricating grease is added, the grease on the steel screw will rotate...
