As shown in fig. 1-3, the present embodiment provides a method for improving the mechanical service life of a manual pulse generator based on the prior art, comprising: the grating component comprises a main body 1, a gear 2, a dial 3, a bearing 7, a spherical ball 13, a spring 14, a jackscrew 15, a grating component 8, a photoelectric conversion component 11, a crank handle 4, a circuit board 10, a stop-back ring 9 and a terminal 12, wherein the bearing 7 comprises a bearing inner ring and a bearing outer ring, the bearing inner ring is sleeved on one end of the gear 2, the main body 1 is sleeved on the bearing outer ring, the dial 3 is buckled on the main body 1, the middle part of the dial 3 is fixed at the other end of the gear 2 through the tight-set jackscrew 6, the dial 3 is provided with scale marks 3-2, the crank handle 4 is rotatably installed on one side, far away from the main body 1, of the dial 3, the grating component 8 is sleeved on one end boss of the gear 2 and matched, the stop-back ring 9 is sleeved on one end of the gear 2, the. The circuit board 10 is fixed on the side of the body 1 far away from the dial 3 by screws, the photoelectric conversion part 11 is fixed on the circuit board 10 by welding, the terminal 12 is a processing circuit and an output terminal, the terminal 12 is fixed on the side of the circuit board 10 far away from the gear 2 by welding, and the grating part 8 is matched with the U-shaped opening of the photoelectric conversion part 11. That is, when the manual pulse generator has an external force (mainly by hand) to drive the rocking handle 4, so that the dial 3 rotates, the dial 3 drives the gear 2 and the grating disk 8 to rotate simultaneously through the shaft of the gear 2, in the process of rotating the gear 2, the grating component 8 rotates simultaneously, infrared light emitted by the diode arranged on the photoelectric conversion component 11 forms a regular optical signal after passing through the grating component 8, the photoelectric conversion processing module arranged on the photoelectric conversion component 11 receives the regular optical signal to generate a regular electrical signal, and after the regular electrical signal is processed by the processing circuit arranged on the circuit board 10, a pulse signal which can be used by a user is finally generated, and the pulse signal is provided for devices such as a PLC and the like through the output terminal 12 arranged on the circuit board.

The side of main part 1 be equipped with the same high round through-hole in gear 2 center, spherical ball 13, spring 14 and jackscrew 15 are installed in round through-hole in proper order, spherical ball 13 cooperatees with the tooth of 2 excircles of gear, spherical ball 13 is near with gear 2's tooth form angle both sides, spring 14 is installed between spherical ball 13 and jackscrew 15, the jackscrew 15 outside is equipped with the external screw thread, round through-hole inboard is equipped with the internal thread, jackscrew 15 passes through bolted connection to be fixed in round through-hole, jackscrew 15 can adjust spring 14's elasticity, thereby adjust the pressure size of realizing between spherical ball 13 and the gear 3, adjust the size of driven feeling.
