Embodiment Construction

[0024] The scheme will be further described below in conjunction with the accompanying drawings.

[0025] The high-precision non-contact tooth-aligning probe 1 is installed on one end of the 3-axis of the grinding wheel, so it can move along the radial, tangential, and axial directions of the workpiece with the help of the linear motion axis of the machine tool; the shaft gear 21 has been ground to the size required by the drawing and precision, press-fit the unground disc gear 22 to the shaft gear 21 to form the press-fit duplex gear 2, and mark the overlapped tooth slot positions during the press-fit.

[0026] A method for centering grinding of two tooth slots of a press-fit double gear, comprising the following steps:

[0027] Step A. Fix the position of the grinding wheel 3 according to the slot marked during pressing: snap the tooth body of the grinding wheel 3 into the slot in the press-fit double gear 2, and the slot is the middle plate gear 22 of the press-fit double g...

Abstract

The invention discloses a pressing duplex gear tooth groove centering grinding method. The method comprises the steps that the position of a grinding wheel is fixed according to a clamping groove marked during pressing; a grinding machine tool takes the position of the grinding wheel and the position of a pressing duplex gear as synchronous reference positions, and grinds disk gears in the pressing duplex gear according to the reference positions; secondary tooth alignment of the pressing duplex gear is realized according to a non-contact tooth alignment side head, and grinding of the first pressing duplex gear is completed; and subsequent grinding of a plurality of pressing duplex gears is completed according to the grinding machining of the first pressing duplex gear. Secondary tooth alignment of the pressing duplex gear is realized through the non-contact tooth alignment side head, the requirement for pre-grinding precision of the disk gears and the requirement for the precision ofdirect tooth groove coincidence of the disk gears and a shaft gear during pressing are lowered, and the production cost is reduced while the product qualification rate is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for centering and grinding of tooth slots of press-fit double gears. Background technique [0002] Press-fit double gear means that the gear assembly is composed of two gears, usually one of which is a shaft gear and the other is a disc gear. The grinding process of press-fit double gear is as follows: first grind the shaft gear to the size and accuracy required by the drawing, then press the disc gear to the shaft gear, and then grind the disc gear to the size and accuracy required by the drawing; usually , this type of press-fit double gear has a special technical requirement, that is, it is required that on the final ground product, the center of a certain tooth groove on the two gears should coincide (required degree of coincidence: less than 0.03mm); at present In order to process this type of gears on a worm grinding wheel gear grinding machine and m...
