The sprocket should be mounted on the shaft without skew and sway. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprocket is less than 0.5 m, the deviation is 1 mm. When the center distance of the sprocket is 0.5 m

1. The allowable wear value of the chain shall not exceed 10% of the diameter of the ring chain or the thickness of the accessory;2. From the plane where the main ring is not bent, the main ring is distorted by more than 10 degrees and should be scrapped;3. Cracks appearing in any part of the chain,

1. In order to remove the play of the entire chain, it is measured under a certain degree of pulling tension on the chain;2. When measuring, in order to minimize the error, measure in the 6-10 section (link);3. Measure the number of the inner side L1 and the outer side L2 between the number of rolle

1. After the measurement, the chain is cleaned;2. The chain to be tested is placed on the two sprockets, and the upper and lower sides of the tested chain should be supported;3. The chain before the measurement should be stopped for 1 min under the condition of applying one-third of the minimum ulti

1. Whether the inner/outer chain is deformed, cracked or embroidered;2. Whether the pin is deformed or rotated, embroidered;3. Whether the roller is cracked, damaged, excessively worn;4. Whether the joint is loose or deformed;5. There is no abnormal sound or abnormal vibration during operation, and

1. Transmission chain: It is mainly used to transmit power chain.2. Conveyor chain: mainly used to transport the chain of materials.3. Traction chain: mainly used for pulling and lifting chains.4. Special special chain: mainly used on special mechanical devices, with special functions and structure

In the same kind of products, according to the basic structure of the chain, that is, according to the shape of the component, the parts and parts engaged with the chain, the size ratio of the parts, etc., the product series of the chain is divided.1. Lifting chain varietyIn the same series of chain

The cargo net is a cargo net made of rope-like fibers that can be lifted by a lifting device for lifting and transporting fine goods. The material of the cargo net can be made of synthetic plastic fiber such as nylon or steel fiber. The hanging net made of plastic fiber is relatively dense, and it c

First: choose the sling from the conceptThe steel wire rope is made of steel wire rope as raw material, mainly including phosphating coated steel wire rope, galvanized steel wire rope and smooth steel wire rope. It is used for lifting, pulling, tensioning and carrying ropes. It has high specific str

China has entered the era of industrial production of slings.The sling is the auxiliary material for production and construction, and the development of the sling market is closely related to economic development. Before November 2008, due to the rapid economic development, China's economy has advan
