Medical drug material conveying omega-shaped double bolt closed transmission system

Abstract

The invention provides a medical drug material conveying omega-shaped double bolt closed transmission system. The medical drug material conveying omega-shaped double bolt closed transmission system isconstituted by a chain formed by vertically-placed and horizontally-placed omega-shaped closed chain rings which are alternately connected with each other; as for the omega-shaped closed chain rings,the connected parts are provided with planes, and the connected parts are mutually connected in a face-contact mode; and the omega-shaped closed chain rings comprise omega-shaped bodies, and chain ring sealing double fastening bolts which are mounted at the opening ends of the omega-shaped bodies. According to the medical drug material conveying omega-shaped double bolt closed transmission system, mounting and dismounting are easy, overhauling and maintaining are convenient, the cost is low, the chain rings are in face-contact transmission, the bearing capacity is large, the contact stress issmall, abrasion resistance is achieved, the pitch is not changed, transmission is stable, precise transmission can be achieved, the service life is long, and thus the medical drug material conveyingomega-shaped double bolt closed transmission system can be widely applied to a medical drug material conveying equipment transmission system.

Description

technical field [0001] The invention relates to an omega-shaped double-bolt closed transmission system for medical drug material delivery, which can be widely used in the transmission system of medical drug material delivery equipment. Background technique [0002] The existing medical and drug material conveying equipment relies on the chain to drag the carrier, and relies on the carrier to realize the material transportation. In the traditional round link chain, the chain links are made of round steel, and all the links have the same structure. When used, they are divided into flat rings and vertical rings according to their positions. In the traditional ring chain structure, since the bending radius of the ring is larger than the radius of the round steel, the chain links form a line contact transmission. When the line contact is under the same force, the contact surface of the link is small, the stress is large, and it is easy to wear. [0003] According to the structur...

AI Technical Summary

Problems solved by technology

The line contact generated by the above analysis of its structure is prone to wear and tear, and the pitch of the chain ring will increase after wear and tear. The change of the pitch will cause the transmission to be unstable, and the instability will aggravate the wear, thus causing a vicious circle and making the chain life extremely long. Low

This kind of structural characteristics due to different pitch changes due to different redirection angles also brings difficulties to the standardization of conveying equipment manufacturing

[0004] The traditional ring chain is welded and closed, and it needs to be cut according to the actual length when used, which will cause waste

It is necessary to add an additional connecting link when docking. The price of one connecting link is about the price of a two-meter chain, and the cost is high

When there is a problem with a chain link, gas cutting is usually used to dismantle it destructively. Not only is it difficult to repair and maintain, it takes a long time, but also needs to prepare repair tools, set up flammable and explosive gas safety protection, and cause environmental pollution and other disadvantages
