The Production Process for Cardan Shafts

Machinery and equipment are usually made up of three parts: the moving parts, the transmission, and the working mechanism, and the coupling is what connects them together. Important components. A coupling is a shaft component used to connect shafts in a mechanical drive, although it can also be used to connect shafts to other rotating parts. Its main task is to transmit torque. Compared to belt, chain, and gear drives, the use of couplings has unique and irreplaceable advantages. The transmission shaft has the advantages of simple structure, high strength, and long service life, etc. The universal coupling as a transmission structure has the advantages of simple structure, high strength, and long service life.

As the core component in the transmission structure, the universal coupling is widely used in various engineering fields. The cost of the coupling itself is high, and its manufacture and assembly require high technical requirements and fitting precision. The standard JB/T5513-2006 "SWC type integral forkhead cross shaft universal coupling" and the standard JB/T5513-2006 "SWC type integral forkhead cross shaft universal coupling" issued by the Ministry of Machinery are the standards. JB/T7341-1994《SWP type, SWC type cross shaft universal coupling cross package type and size》

The different structures of the cross packs can be divided into SWC type and SWP type, while the intermediate shaft coupling can be divided into seven major categories. BH-Standard telescopic welded universal coupling, BF-Standard telescopic flange universal coupling, DH-Short telescopic coupling, BH-Standard telescopic welded universal coupling, BH-Standard telescopic flange universal coupling, Welded Universal Coupling, CH-Long Retractable Welded Universal Coupling, WH-Non-retractable Welded Universal Coupling, WF-Non-retractable Welded Universal Coupling etc. Telescopic flange universal coupling, WD- non-telescopic short universal coupling. According to JB/T5513-2006 Standard JB/T5513-2006 SWC Type Whole Fork-Head Cross Shaft Universal Coupling issued by the Ministry of Machinery and Standard JB/T7341-1994 "SWP type, SWC type cross shaft universal joint cross package type and size".

Processes and process steps in the machining of drive shafts.

1, First of all, the forging blank at both ends of the central hole drilling, rough car outside a few big steps.

2, Conduct tempering.

3, Semi-precision car steps, outer circle and length of the spare, and then take the center frame car to the total length.

4, Drilling of through holes in the central frame.

 5, Enamel tapered holes at both ends, bore bored heads at both ends, and drill center holes to prepare for grinding.

 6, Fine turning of each gear outer circle and step plane with grinding allowance, and chamfering of each groove on the outer circle.

 7, Grinding all kinds of cylindrical and step planes to size.

 8, Process each thread on this lathe after assembly.

The transmission shaft is dynamically balanced before leaving the factory and is adjusted on the balancing machine. For the front engine and rear-wheel-drive cars, it is the shaft that transmits the rotation of the transmission to the main reducer, which can be several knots, knuckle to knuckle. Between can be connected by the gimbal.

Extended information.

The conventionally constructed drive shaft telescopic sleeve is made by welding the spline sleeve to the flange fork and the spline shaft to the Cardan Shaft tube. The new Cardan Shaft changes the traditional structure by welding the spline sleeve to the Cardan Shaft tube and the spline shaft to the camshaft fork as one piece. The rectangular toothed spline is replaced by a short toothed spline with a large pressure angle involute, which increases strength and is easy to extrude to accommodate high torque. The need for working conditions.

The teeth of the expansion sleeve and spline shaft are coated with a layer of nylon, which not only increases abrasion resistance and self-lubrication but also reduces the impact load damage to the Cardan Shaft and improves the cushioning capacity.

It is designed to reduce friction and wear during shaft movement, and its basic purpose is the same as that of a bearing. They have higher frictional resistance, so they are only used in some parts. Most bushings are made of copper, but plastic bushings are also available.

The sleeve is placed between the shaft and the support and is so close to the support that only the shaft can rotate on the sleeve. When assembling the shaft and the sleeve, a lubricant is added between them to reduce the friction caused by their rotation.
