Abstract
The utility model relates to a speed change device, in particular to a single-stage transmission stepless speed change device, which has a speed-regulating shaft, the speed-regulating shaft is provided screw threads and is driven by a speed-regulating hand wheel to rotate. A speed-regulating bearing seat is mounted on the speed-regulating shaft, and a screw hole and a smooth surface hole are arranged on the speed-regulating bearing seat. A driven conical gear mounted on the lower end of the speed-regulating shaft is engaged with a driving conical gear, a speed-regulating hand wheel is mounted on the driven conical gear. 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, speed change is accurate, the self-locking effect is good after the speed is changed, moreover, the utility model can meet the requirement of constant power transmission in a wide speed change range and realize continuous speed change and regulation of delicate rotational speed, the production cost is low, 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, and the speed governing axle is by the speed-regulating hand wheel driven rotary.The speed regulating bearing seat is installed on the speed governing axle, is offered tapped hole and light face on the speed regulating bearing seat.Driven wheel of differential is installed in speed governing axle lower end, 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:
6 is speed governing axles among the figure, and screw thread 7 is set on the speed governing axle 6, and speed governing axle 6 is by the speed-regulating hand wheel driven rotary.Speed regulating bearing seat 8 is installed on the speed governing axle 6, is offered tapped hole 9 and light face 10 on the speed regulating bearing seat 8.Driven wheel of differential 2 is installed in speed governing axle 6 lower ends, and driven wheel of differential 2 and drive bevel gear 5 engagements are installed speed-regulating hand wheel 3 on the drive bevel gear 5.6 on speed governing axle of the present utility model is done and is revolved the axle motion, does not do moving up and down, so the self-locking property of speed governing is good, can realize fine speed governing etc.The utility model is installed on the machining apparatus that adopts the belt transferring power when using, the light face 10 of speed regulating bearing seat 8 matches with the main shaft on the equipment, when needing speed governing, rotate speed-regulating hand wheel 3, driving speed governing axle 6 by drive bevel gear 5 and driven wheel of differential 2 rotates, promoting speed regulating bearing seat 8 moves up and down, and then the diametrical position that contacts with driving belt of the drive wheel on the change equipment, reach the purpose of speed change, 1 is supporting sleeve among the figure, the 4th, supporting sleeve is used for the utility model is installed on the equipment support when using.
