An integrated production process of spline sleeve transmission shaft tube

Abstract

The invention discloses an integrated production technology for spline housings and transmission shaft pipes. The integrated production technology comprises the steps of heating alloy steel to the melting point for obtaining molten alloy steel; placing the molten alloy steel into a spline housing die and a transmission shaft pipe die and obtaining spline housing work-pieces and transmission shaft pipe work-pieces after cooling; carrying out electric resistance welding on the connection parts of the spline housing work-pieces and the transmission shaft pipe work-pieces and obtaining integrated work-pieces after welding; slowly heating the integrated work-pieces to 900 DEG C, maintaining the temperature for 3 hours and then carrying out annealing; placing the integrated work-pieces subjected to annealing inside an integrated die of the spline housings and the transmission shaft pipes and then pouring an additional alloy steel layer with the thickness not greater than 5 mm on the surface of the integrated die. Compared with the prior art, the technical scheme has the advantages that spline shafts and flange yokes are combined into integrated parts, the die casting method is adopted, quenching, electro-welding and casting of connectors are adopted, a pulse scanner is adopted for scanning the work-pieces, a five-axis computer numerical control machine tool is adopted for machining, the efficiency is improved, and the quality is guaranteed.

Description

technical field [0001] The invention relates to the field of processing technology for the intermediate flange of a transmission shaft, in particular to an integrated production process for a spline sleeve transmission shaft tube. Background technique [0002] The transmission shaft is a rotating body with high speed and few bearings, so its dynamic balance is very important. Generally, the transmission shaft must undergo a dynamic balance test before leaving the factory and adjust it on a balancing machine. For a car with a front-engine rear-wheel drive, it is the shaft that transmits the rotation of the transmission to the final drive. It can be several knots. Yes, joints can be connected by universal joints; in today's integrated production process of spline sleeve transmission shaft tube, most enterprises still use manual or manual mechanical methods to connect spline sleeve and drive shaft The tubes are produced separately, which not only requires high investment, but ...

Generally, the transmission shaft must undergo a dynamic balance test before leaving the factory and adjust it on a balancing machine. For a car with a front-engine rear-wheel drive, it is the shaft that transmits the rotation of the transmission to the final drive. It can be several knots. Yes, joints can be connected by universal joints; in today's integrated production process of spline sleeve transmission shaft tube, most enterprises still use manual or manual mechanical methods to connect spline sleeve and drive shaft The tubes are produced separately, which not only requires high investment, but also consumes manpower and material resources. At the same time, the quality of the spline sleeve and the transmission shaft tube cannot be fully guaranteed, and the production efficiency is reduced.
