Abstract

The invention relates to a method for designing a shaft coupling of a brake fluid charging / discharging machine of an automobile. The end edge of a half shaft coupling of a driving shaft is provided with a parallel surface which is symmetrical to an axis so as to form a drum type boss; the end edge of a half shaft coupling of a driven shaft is provided with a parallel surface which is symmetrical to the axis so as to form a drum type boss; a cross-shaped groove block is arranged between the drum type boss of the half shaft coupling of the driving shaft and the drum type boss of the half shaft coupling of the driven shaft; one end of the cross-shaped groove block is provided with a parallel surface which is symmetrical to the axis so as to form a drum type groove, while the other end is provided with a parallel surface which is symmetrical to the axis so as to form a drum type groove; the notches of the two drum type grooves are opposite to each other and an included angle of 90 degrees is formed between the notches in the radial direction; the drum type boss of the half shaft coupling of the driving shaft is matched with the drum type groove at one end of the cross-shaped groove block; and the drum type boss of the half shaft coupling of the driven shaft is matched with the drum type groove at the other end of the cross-shaped groove block. In a rotating process, the cross-shaped groove block can slide in various directions so as to meet the requirement of the shaft coupling on compensating conditions such as radial deviation, axial deviation or axis deflection and crossing and the like caused by the installation of two shafts.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a design method for a coupling of an automobile brake fluid charging and discharging machine. Background technique [0002] In the known cross shaft coupling and cross slider coupling, the former is connected by the cross shaft to the two halves of the coupling, which can rotate and transmit torque under the condition that the axes of the two shafts are skewed and intersected; the latter is embedded by the cross slider boss. The half-couplings at both ends of the shaft are connected in the end grooves, which can rotate and transmit torque under the condition that the two shafts have axial and radial installation deviations. If there are radial and axial deviations between the two shafts or the axes have a certain crossing angle, the above two couplings cannot operate normally. In addition, the instantaneous angular velocity of the driving shaft and the driven shaft changes during the rotation...
