Abstract
An omega-shaped single-bolt closed transmission device for conveying medical drug materials is composed of chains formed by alternately connecting vertically-placed and horizontally-placed omega-shaped closed chain rings; the connecting parts of the omega-shaped closed chain ring are planes, and the omega-shaped closed chain ring is in surface contact with each other; the omega-shaped closed chain ring comprises an omega-shaped body, and a chain ring seal fastening bolt arranged at the opening end of the omega-shaped body. The omega-shaped single-bolt closed transmission device for conveying medical drug materials is easy to mount and dismount, convenient to overhaul and maintain, low in cost, large in bearing capacity, small in contact stress, wear-resistant, stable in transmission, capable of realizing precise transmission and long in service life, and the chain rings are in surface contact transmission. The transmission system can be widely applied to the transmission system of medical drug material conveying equipment.
Description
Technical Field
The invention relates to an omega-shaped single-bolt closed transmission device for conveying medical drug materials, which can be widely applied to a transmission system of medical drug material conveying equipment.
Background
The existing medicine and drug material conveying equipment drags the bearing body by a chain and realizes the conveying of materials by the bearing body. Traditional round-link chain, chain link are woven by the round steel and form, and all chain link structures are the same, divide into flat ring and found the ring according to the position difference during the use. In the traditional circular chain structure, the bending radius of the circular ring is larger than that of round steel, so that the chain rings form linear contact transmission, and when the linear contact is under the same acting force, the contact surface of the chain rings is small, the stress is large, and the chain rings are easy to wear.
A structure with the bending radius larger than that of the round steel is compiled according to the circular ring of the circular ring chain, namely, the turnabout turning center line is not overlapped with the center line of the chain ring; this arrangement produces a pitch change during redirection, i.e. both relative rotation and relative sliding between the links. The pitch is reduced by a different amount for different redirection angles, and this change in pitch increases transmission instability. The line contact that its structure of above-mentioned analysis produced easily produces wearing and tearing, and the pitch of wearing and tearing back chain ring can increase again, and the change of pitch can bring the transmission unstability, and unstability can aggravate wearing and tearing to cause vicious circle, make the chain life-span extremely low. The structural characteristics of different change of the direction change angle and different pitch also bring difficulty to the manufacturing standardization of the conveying equipment.
The traditional annular chain is formed in a welding and sealing mode, and needs to be intercepted according to the actual length during use, so that waste is generated. When in butt joint, an additional connecting ring needs to be added, the price of one connecting ring is about two meters of the price of the chain, and the cost is high. When a certain chain ring has a problem, the chain ring is usually demolished destructively by gas cutting, which not only has difficult maintenance and long time consumption, but also needs to prepare a maintenance tool, set up safety protection of flammable and explosive gases, and causes the defects of environmental pollution and the like.
Disclosure of Invention
The invention aims to provide the omega-shaped single-bolt closed transmission device for conveying medical drug materials, which is easy to install and disassemble, convenient to overhaul and maintain, low in cost, large in bearing capacity, small in contact stress, wear-resistant, stable in transmission, capable of realizing precise transmission and long in service life, and has no change in pitch.
In order to achieve the aim, the omega-shaped single-bolt closed transmission device for conveying medical drug materials is composed of chains formed by alternately connecting vertically-placed omega-shaped closed chain rings and horizontally-placed omega-shaped closed chain rings; the connecting parts of the omega-shaped closed chain ring are planes, and the omega-shaped closed chain ring is in surface contact with each other; the omega-shaped closed chain ring comprises an omega-shaped body, and a chain ring seal fastening bolt arranged at the opening end of the omega-shaped body.
The omega-shaped single-bolt closed transmission device for conveying medical drug materials adopts a bolt structure, is easy to install and disassemble, convenient to overhaul and maintain, capable of being partially replaced and low in cost.
Compared with the traditional round-link chain, the omega-shaped single-bolt closed transmission device for conveying medical drug materials has essential difference in structure. The chain rings are in surface contact transmission, so that the bearing capacity is high, the contact stress is small, the chain rings are wear-resistant, the pitch cannot be changed, the connection is reliable, the transmission is stable, the precise transmission can be realized, and the service life is long.
The omega-shaped single-bolt closed transmission device for conveying medical drug materials has the same structure of the vertically placed omega-shaped closed chain ring and the horizontally placed omega-shaped closed chain ring, can realize standardized mass production, and is convenient to replace.
In conclusion, the omega-shaped single-bolt closed transmission device for conveying medical drug materials is easy to mount and dismount, convenient to overhaul and maintain, low in cost, large in bearing capacity, small in contact stress, wear-resistant, stable in transmission, capable of realizing precise transmission and long in service life, and the chain rings are in surface contact transmission.
