Abstract
The utility model relates to a speed change device, in particular to a two-stage transmission stepless speed change device. The utility model has a speed-regulating shaft, the speed-regulating shaft is provided screw threads and a shifting fork body, and the inner screw threads of the shifting fork body matches the screw threads of the speed-regulating shaft which is driven by a speed-regulating hand wheel to rotate. The utility model can be used on various mechanical processing devices applying strap transmission, so the devices can realize stepless speed change, the operation of speed change can be simple, quick and laborsaving, speed change does not require the devices to stop running and is accurate, the self-locking effect is good after the speed is changed, and the utility model can meet the requirement of constant power transmission in a wide speed change range, can realize continuous speed change, and so on.
Description
Technical field:
The utility model relates to speed change gear, is a kind of twin-stage drive stepless speed changing device.
Background technique:
Though the stepless speed changes devices of claimant's application has more advantage, can make equipment realize stepless change, but find that after further research still there is some deficiency in it: accuracy and the self-locking state after the speed change during speed change are not good enough, difficulty satisfies fine speed change request etc.
Summary of the invention:
The purpose of this utility model is; a kind of twin-stage drive stepless speed changing device is provided; make it have following advantage: it can be applied on the various employing bel-drivenn machining apparatus; make this equipment realize stepless change, can accomplish that variable speed operation is simple, quick, laborsaving, do not need equipment downtime during speed change; speed change is accurate; self-locking after the speed change is effective, can satisfy the requirement of permanent power transmission in maximum slewing range, realizes continuously uninterrupted speed change etc.
The utility model adopts following scheme to solve in order to solve the existing in prior technology problem, and it has the speed governing axle, on the speed governing axle screw thread is set, the shift fork body is installed on the speed governing axle, the threads engaged on internal thread on the shift fork body and the speed governing axle, the speed governing axle is by the speed-regulating hand wheel driven rotary.Lower shift fork on the shift fork body can be an one with the shift fork body, and upper shift fork adopts fastening piece to be installed on the shift fork body.Driven wheel of differential is installed in the lower end of speed governing axle, and speed-regulating hand wheel is installed in driven wheel of differential and drive bevel gear engagement on the drive bevel gear.
Advantage of the present utility model is as follows: it can be installed on the various employing bel-drivenn machining apparatus and use; make this equipment realize stepless change; variable speed operation is simple, quick, laborsaving; do not need equipment downtime during speed change, speed change is accurate, and the self-locking after the speed change is effective; can realize the adjustment of fine rotating speed; can in maximum slewing range, satisfy the requirement of permanent power transmission, realize continuously uninterrupted speed change, low cost of manufacture etc.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model, accompanying drawing 2 be in the accompanying drawing 1 A to view, accompanying drawing 3 be in the accompanying drawing 2 B to view.
Embodiment:
9 is speed governing axles among the figure, and screw thread 7 is set on the speed governing axle 9, and shift fork body 8 is installed on the speed governing axle 9, and the internal thread on the shift fork body 8 matches with screw thread 7 on the speed governing axle 9, and speed governing axle 9 is by the speed-regulating hand wheel driven rotary.Lower shift fork 1 on the shift fork body 8 can be an one with shift fork body 8, and upper shift fork 10 adopts fastening piece to be installed on the shift fork body 8.Driven wheel of differential 3 is installed in the lower end of speed governing axle 9, and driven wheel of differential 3 and drive bevel gear 6 engagements are installed speed-regulating hand wheel 4 on the drive bevel gear 6.During the utility model speed governing, rotate speed-regulating hand wheel 4, by drive bevel gear 6 and driven wheel of differential 2, drive speed governing axle 9 and rotate, 9 on speed governing axle rotates, and does not do moving up and down.Because the utility model is installed on the machining apparatus when using, shift fork is installed on the bearing support of the drive wheel that needs adjustment, so when speed governing axle 9 rotates, promoting shift fork body 8 moves up and down, and then stir drive wheel by shift fork and move up and down, change the diametrical position that drive wheel contacts with driving belt, reach the purpose of speed change.2 is supporting sleeves among the figure, the 5th, and supporting sleeve is used to be installed in the support when using on the equipment.
