Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized spider coupling manufacturer and custom spider couplings designer of various kinds of conveyors, belts, pulleys, bearings, rollers, bushings and so on. Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

This product has been the European standard jaw coupling, as well as in many other parts of the world. The three-piece design incorporates a radial curvature to the jaw face, and both radial and axial curvature (crowning) to the elastomer (spider). The Curved Jaw Coupling provides highly reliable service for light, medium, and heavy duty electrical motor and internal combustion engine power transmission applications. Curved Jaw Couplings are distributed worldwide to support OEM`s and the users of their equipment. Improved torsional softness. Angular misalignment capability of up to 1.3. No lubrication required. No metal-to-metal contact. Fail-safe � will still perform if elastomer fails. Easy installation.
Three shore hardnesses of urethane open center type elastomers available. Urethane spiders provide high abrasion resistance and elasticity, along with good. damping characteristics. Resistant to oil, dirt, sand, grease, moisture, many solvents, as well as the atmospheric effects of ozone. Both rough stock bores and finished in/metric bores available. Torque range of 35 in-lbs to 66,375 in-lbs

Electromagnetic clutches are also found in PIV drives. These types are found in PIV drives used in the paper industry. Electromagnetic clutches found in G3A5DU PIV drives of an internal clutch assembly (tracking plate, kick-in plate and coil) plus a set of external brushes. The internal clutch assembly is replaced as a unit, while it is possible to replace the external brushes and brush holders. Another type of electromagnetic clutch consists of two parts and is found in multi-step gearboxes. Soft start" couplings are used to prevent sudden jerking motions which can damage the drive or machinery when torque is suddenly applied to the shaft. These couplings usually consist of semi-elastic inserts (usually rubber or plastic) inside a metal housing, which stretch when torque is applied, thereby allowing for a gradual increase in torque to the output shaft. We usually supply our customers with the replacement inserts. The Jaw couplings from Lovejoy are offered in the industry’s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy-duty electrical motor and internal combustion power transmission applications.
