Problems solved by technology

With the rapid development of acupuncture non-woven fabrics, the requirements for the quality, performance, and frequency of acupuncture machines are getting higher and higher. The high-speed acupuncture machines produced in China can theoretically reach a frequency of 1500 times per minute, but In the actual production process, due to the use of a mechanical structure combining eccentric sleeves and bearings, the processing accuracy, rigidity, and positioning accuracy of the acupuncture machine during the manufacturing process cannot achieve the ideal results. Therefore, the acupuncture frequency of the acupuncture machine It only reaches 1000-1200 / minute, which brings a series of problems to the improvement of product quality and production efficiency

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings, wherein the "front" in this specification refers to the attached Figure 4 on the left side, correspondingly, the "rear" side mentioned in the instructions refers to the attached Figure 4 on the right side of the .

[0027] The invention discloses an eccentric connection assembly, see the attached image 3 And attached Figure 4 As shown, it includes: an outer ring 71, an inner ring 73 coaxially rotated inside the outer ring 71, a rolling member 72 arranged between the outer ring 71 and the inner ring 73, the rolling The member 72 includes a cage 721 and a plurality of rolling elements 722 rotatably connected to the cage 721 . The inner ring 73 is provided with a tapered hole at a place deviated from the axis. The tapered hole extends from the rear end of the inner ring 72 to the front end, and the diameter gradually becomes smaller. The tapered hole is provided wi...

Abstract

The invention relates to an eccentric connecting component and a needling machine with the same. The eccentric connecting component comprises an outer ring, an inner ring and a rolling part, wherein the inner ring is coaxially rotationally arranged inside the outer ring, the rolling part is disposed between the outer ring and the inner ring, and the inner ring is provided with a taper hole with acaliber narrowing gradually. Besides, a shaft sleeve used for connecting a shaft is arranged inside the taper hole, the hole wall of the taper hole has the same conical degree with the outer circumferential surface of the shaft sleeve, the axis line of the shaft sleeve is deviated from the axis lines of the outer ring and the inner ring, the lateral wall of the shaft sleeve is cut by a plane to form an expansion joint, and the plane is parallel to the direction of the axis line of the shaft sleeve. When radial load exerted on the shaft sleeve changes, the size of an opening of the expansion joint changes along with the radial load; moreover, the hardness of the inner ring is larger than that of the shaft sleeve. The component and the needling machine have the advantages of convenient installation and long service life, and experiments prove that needling efficiency can reach 2000 revolutions per minute by applying the needling machine.

Description

technical field [0001] The invention relates to a shaft connection assembly capable of realizing eccentric transmission. Background technique [0002] In the mechanical field, linear reciprocating motion is often converted into linear motion by using an eccentric mechanism. Commonly used eccentric mechanisms include cam mechanisms or eccentric bearings. The disadvantage of cam mechanisms is that after long-term work, the cams will wear out and deform, resulting in no longer transmission. Accurate, in addition, the cam mechanism is suitable for low-speed operation, and the noise pollution is quite serious during high-speed operation; the disadvantage of the eccentric bearing is that the working clearance between the inner ring and the outer ring is too small after installation, and the interference fit between the outer ring and the connecting rod The outer ring bears an inward force, and the shaft and the inner ring are also interference fit, so the inner ring bears an outwa...
