Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Please also see Figure 1-Figure 5 . The invention provides a worm gear transmission, such as Figure 1-3 As shown, it includes: a frame 1, a power supply, a worm wheel 2 arranged on the frame 1, a worm assembly arranged on the frame 1 and meshed with the worm wheel 2, a sliding device arranged on the lower surface of the worm assembly, and a set An elastic device on the end of the worm assembly away from the worm wheel 2; the elastic device connects the frame 1 with the worm assembly; when the elastic deformation of the elastic device resumes, the worm assembly drives the slidi...

Abstract

The invention discloses a screw gearing comprising a rack, a power supply, a worm component arranged on the rack and engaged with a worm gear, a sliding device arranged below the worm component and an elastic device arranged on one end of the worm component away from the worm gear, wherein the elastic device connects the rack with the worm component. When the elastic device recovers the elastic deformation, the worm component drives the sliding device to move toward the worm gear; and the worm component is connected with the power supply through a coupling. When the elastic device is clamped between the rack and the worm component and the worm component is in engaged transmission with the worm, the elastic device is always in a compressed state. In the case of abrasion of the worm gear and the worm, a space for recovering the elastic deformation is provided for the elastic device, the elastic device can only recover the deformation toward the direction of the worm component under the limiting function of the rack, and the worm component drives the sliding device to move toward the worm gear so as to eliminate a tolerance clearance caused by the abrasion of the worm gear and the worm, thereby improving the precision of the screw gearing.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a worm gear transmission device. Background technique [0002] Worm gear transmission is commonly used in mechanical transmission equipment, but after long-term use, the worm gear and worm will wear to a certain extent, resulting in the inability to cooperate with high precision between the worm gear and the worm, and there is a gap, making the transmission mechanism of the worm gear unsuitable for High-precision precision equipment. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a [0005] The worm gear transmission device aims to solve the problems in the prior art that the worm gear is easy to wear after a long period of use, resulting in fit gaps and low precision. [0006] The technical solution adopted by the present ...
