Abstract
The change gear has both spur toothed gear and bevel toothed gear moulded in one single process. When the bevel toothed gear as worm gear is driven by one double worm with one pair of symmetrical right-handed and left-handed threads, the small bevel toothed gear coaxial with the worm gear drives one large gear, and this can result in large transmission area, smooth and reliable operation and low noise.
Description
The present invention relates to a kind of straight, helical teeth speed change gear of single injection-molded, is a spur gear and the speed change gear that bevel gear set is synthetic specifically.
Gearbox of the same type for a long time, form by a secondary worm gear and worm screw, produce the axial force of band directivity during gear operation that this worm screw drives, when normal operation, can influence the working state of complete machine, and the adjustment that will overcome this axial force is the comparison difficulty, also malfunctioning easily in practical work process, cause the rate of fault height, the life-span is short and volume is big and shortcomings such as heaviness.
The objective of the invention is to avoid above-mentioned deficiency of the prior art, and provide a kind of littler by 30%, improve the spur gear and the synthetic speed change gear of bevel gear set of gear ratio than original volume.
Technical solution of the present invention:
A kind of straight, helical teeth speed change gear is characterized in that it has a spur gear and a helical gear combination to form.
Advantage of the present invention:
The mutual balance of axial force made transmission more steady so need not regulating device when 1, rotation direction each symmetrical double driving worm in the left and right sides drove two worm gear work simultaneously.
2, small Spur gear (two of pairs) drives a gearwheel jointly, and drive area is increased, and gearwheel work is more steady reliably, noise is low.
3, owing to compact structure, it is little to take up room, and saves cost 15%, easy to loading and unloading.
4, each symmetrical double driving worm of left and right sides rotation direction drives this drive mechanism of corresponding worm gear, can improve transmission efficiency 25%.
5, advanced design, rational in infrastructure, the transmission efficiency height, rate of fault is low, long service life.
Fig. 1 is a schematic top plan view of the present invention.
Fig. 2 is a structural representation of the present invention.
Below in conjunction with accompanying drawing the present invention is further described:
1 is small Spur gear among the figure, the 2nd, helical gear, small Spur gear and helical gear single injection-molded are combined into a speed change gear, when about drive helical gear 2 during each symmetrical double driving worm running simultaneously, this moment, helical gear 2 played the effect of worm gear, drove a gearwheel job simultaneously with the coaxial small Spur gear 1 of worm gear under the effect of worm screw.
Claims (2)
1, a kind of straight, helical teeth speed change gear is characterized in that it has a spur gear and a helical gear combination to form.
2, straight, helical teeth speed change gear according to claim 1 is characterized in that spur gear and helical gear are by the plastics single injection-molded.
