Abstract
The utility model discloses a swing angle control device for gear lapping, which comprises an electric motor, a box body, an input shaft and a drive shaft, wherein the input shaft and the drive shaft are arranged on the box body through a bearing; a worm and a worm gear which are meshed with each other are arranged on the input shaft and the drive shaft; and an output shaft of the electric motor is connected with the worm. The swing angle control device is characterized in that a rotary encoder is arranged at the end part of the drive shaft; and an output cable of the rotary encoder is connected with the electric motor. The swing angle control device has the advantages of simple structure and low cost, can set fixed point grinding time in any position so as to amend and grind a gear pair, can effectively control the grinding quality of the gear pair, and can save the grinding time of the gear pair.
Description
Technical field
The utility model relates to a kind of pivot angle control device that is used for gear lapping.
Background technology
Gear lapping is that all spiral bevel gears are processed one of the operation that must carry out, and the quality of gear lapping directly has influence on the noise size and the service life of gear pair; The principle of gear lapping is: on the gear lapping machine of special use, make the gear pair engaged transmission, on gear pair, supply with grinding agent; Utilize the pinion swing mechanism; Make the pinion swing, promptly swing pinion pitch cone bus, with contacting on the canine tooth crop rotation full-depth tooth length; Reach the gear lapping purpose, most critical be the control of steamboat pitch cone swing size.Traditional gear lapping pivot angle control device is as depicted in figs. 1 and 2; Comprise motor (not shown), casing 10, be loaded on power shaft 11, driving shaft 12 and driven shaft 13 on the casing 10 through bearing; Power shaft 11 is provided with the worm screw 14 and worm gear 15 that is meshed with driving shaft 12; Driving shaft 12 links to each other through sprocket wheel link chain mechanism 16 with driven shaft 13; The output shaft of motor is connected with worm screw 14, also is provided with overhead cam 17 at an end of driven shaft 13, on overhead cam 17, is provided with two reverse collision blocks 18 and two excess of stroke collision blocks 19 that shield; All insert in the power circuit of motor being provided with on the casing 1 with two groups of corresponding two signaling switches, 20,21, two signaling switches 20,21 of collision block; When motor drives driven shaft 13 and overhead cam 17 rotations through worm screw 14, worm gear 15, driving shaft 12, sprocket wheel link chain mechanism 16; Reverse collision block 18 on the overhead cam 17 is approaching with corresponding signaling switch 20; Signaling switch 20 conductings; Make the motor backward rotation, thus the pinion backward rotation that drives on the pinion shafts by the cam swing mechanism on the driving shaft 13 22; The pivot angle size of pinion is by the Position Control of the reverse collision block 18 of manual adjustment; The weak point of this structure is: pinion can only swing to the two ends extreme position that sets continuously in swing; Can not pause in the centre; Can not carry out align hone to the gear pair optional position, Grinding Quality that can't the better controlled gear pair, and structure is comparatively complicated, cost is high.
The utility model content
The purpose of the utility model is the above-mentioned deficiency to prior art; A kind of gear lapping pivot angle control device is provided; It has advantage simple in structure, that cost is low; And the fixed point milling time can be set at an arbitrary position gear pair is carried out align hone, the effective secondary Grinding Quality of control gear, the milling time of practicing thrift gear pair.
For achieving the above object; The gear lapping pivot angle control device of the utility model; Comprise motor, casing, be loaded on power shaft and driving shaft on the casing through bearing, power shaft and driving shaft are provided with the worm and worm wheel that are meshed, and the output shaft of motor is connected with worm screw; It is characterized in that being provided with rotary encoder in the end of driving shaft, the output cable of rotary encoder links to each other with motor.
Compared with prior art, the utility model has been cancelled driven shaft, sprocket wheel link chain mechanism, overhead cam, two reverse collision blocks and signaling switch, has advantage simple in structure, that cost is low; The pivot angle number of degrees of driving shaft can be set arbitrarily on the man-machine interface of rotary encoder, and the fixed point milling time can be set at an arbitrary position gear pair is carried out align hone, the effective secondary Grinding Quality of control gear, the milling time of practicing thrift gear pair.
Description of drawings
Fig. 1 is the front view of existing gear lapping pivot angle control device.
Fig. 2 is the vertical view of Fig. 1.
The front view of Fig. 3 the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
By shown in Figure 3; This gear lapping pivot angle control device; Comprise motor (not shown), casing 1, be loaded on power shaft 2 and driving shaft 3 on the casing 1 through bearing, power shaft 2 is provided with the worm screw 4 and worm gear 5 that is meshed with driving shaft 3, and the output shaft of motor is connected with worm screw 4; Be provided with rotary encoder 6 in the end of driving shaft 3, the output cable of rotary encoder 6 links to each other with motor.
The utlity model has advantage simple in structure, that cost is low; The pivot angle number of degrees of driving shaft 3 can be set arbitrarily on the man-machine interface of rotary encoder 6; And can be provided with at an arbitrary position the fixed point milling time gear pair is carried out align hone; Ability is the secondary Grinding Quality of control gear effectively, the milling time of practicing thrift gear pair.
