Abstract
The utility model discloses a single shaft type speed changer, which is composed of a driving wheel, a driven wheel, a driving shaft and a driven shaft, wherein, the driving shaft is a cylindrical fluted disc, and fixedly arranged on the driving shaft; five gear rings with identical modulus are arranged on the cylindrical fluted disc; the driven wheel which is a spur gear with an internal spline has the identical modulus with the driving wheel; the driven shaft which is a spline shaft is vertical with the driving shaft; the driven wheel which is arranged on the driven shaft can slide reciprocally. According to the need of different speed, the five different gear rings on the driving wheel are engaged, and transmission and speed changing are completed with the transmission technology of a column tooth.
Description
The utility model relates to the single axle speed changer.
The variable transmission mechanism pattern of existing ordinary gear speed changer is fixing shaft type gear graduation.Mainly form by gear, axle, hub body and supporting portion.Five speed transmission is a kind of triple axle speed changer of common employing.This speed changer has three main axles, ten several gears.Change velocity ratio by the ordinary gear drive technology and finish transmission and speed change.The ordinary gear drive technology can not conduct on the rigid body to the linear velocity of rotating shaft apart from different particles.That is to say the ordinary gear drive technology, determined triple axle speed changer structure complexity, easy-maintaining does not make trouble, uneconomical gear how much depend on axle and gear how much.
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, economical and practical, the single axle speed changer of kind of drive novelty.
This mechanics of rigid body principle is easily known: when angular velocity one timing of Rigid Body in Rotation With, the linear velocity of particle is directly proportional with the distance of this particle to rotating shaft on the rigid body.Conduct out if will arrive the linear velocity of the particle of rotating shaft different distance, just can obtain different speed.For achieving the above object, the technical solution of the utility model is:
The single axle speed changer is only with driving wheel, follower, and driving shaft and driven shaft constitute.Finish transmission and speed change with post tooth drive technology.
As further improvement of the utility model, single axle speed changer driving wheel (1) is a post fluted disc that is packed on the driving shaft (3).5 gear rings are arranged on the post fluted disc.(each the post tooth on the post fluted disc all has detachability.) its modulus is all identical in follower (2).
As further improvement of the utility model, single axle speed changer follower (2) is an internal spline spur wheel.Be contained on the driven shaft (4), and can reciprocatingly slide.
As further improvement of the utility model, single axle speed changer driven shaft (4) is a splined shaft.Be contained in the position of vertically being divided equally by driving shaft (3).
As further improvement of the utility model, single axle speed changer forward gears has identical velocity variations scope with reverse gear.
As further improvement of the utility model, the single axle speed changer adopts post tooth drive technology.Adopt single axle speed changer of the present utility model, driving wheel (1) upper ring gear how much determining what of gear.Ten thousand kinds of velocity variations are all (4) one of driven shafts.
Specific drive technology has determined the characteristics of single axle speed changer: simple in structure, volume is little, and is easy to manufacture, and materials are economized, the transmission novelty, and speed ratio is big.
Adopt single axle speed changer of the present utility model, friction clutcch can directly be contained in the back side of driving wheel (1), simplifies the locomotive overall structure; Be used on the continuously variable type of automatic transmission, can simplify its complicated hydraulic control system.If operator cabin can be done 180 ° and turns to, vehicle can remove from turn around tired.It is particularly outstanding that this technology is used for police car.
Now in conjunction with the accompanying drawings the utility model is described in detail as follows:
Driving wheel (1) is that (Fig. 1-a, 1-b are its Mechanical drawing sketches to a post fluted disc.) because of being contained on the driving shaft (3).The post fluted disc is by driving disc (Fig. 1-a) and post gear ring (Fig. 1-b) constitute.It is on 5 concentric circles in the center of circle that 220 post perforations are distributed in the driving disc center of circle.Distance on 5 circumference between adjacent two holes all equates.220 post teeth are packed in (each post tooth all has detachability) on 220 post perforations.5 gear rings that modulus equates have been constituted.Possessed 10 speed, Here it is post fluted disc.
Follower (2) is an internal spline spur wheel, and is identical with driving wheel (1) modulus, and its thickness is less than the distance between last adjacent two gear rings of driving wheel (1).The two ends of each tooth are convex surface shape, to avoid two grades with hanging, alleviate the between cog collision.Driven shaft (4) is a splined shaft.Be contained in the position of vertically being divided equally by driving shaft (3).Follower (2) is contained in driven shaft (4), and under the manipulation situation, follower (2) can reciprocatingly slide on driven shaft (4).According to velocity magnitude, the needs of advance and retreat are allocated to corresponding position with follower (2), conduct out with the gear ring engagement with required speed, are exported by driven shaft (4) simultaneously.Thereby finish transmission and speed change.The size of speed, the variation of direction are all (4) one of driven shafts.Consolidate model utility and be called the single axle speed changer.
Claims (4)
1. a single axle speed changer comprises driving wheel (1), follower (2), driving shaft (3) and driven shaft (4), it is characterized in that: driving wheel (1) is a post fluted disc, be packed on the driving shaft (3), driven shaft (4) is a splined shaft, be contained on the position vertical with driving shaft (3), follower (2) is an internal spline spur wheel, is contained on the driven shaft (4), follower (2) can reciprocatingly slide on driven shaft (4), and respectively with driving wheel (1) on the engagement of 5 gear rings.
2. single axle speed changer as claimed in claim 1 is characterized in that: driving wheel (1) comprises driving disc, post tooth, and 220 post teeth are packed on 220 post perforations of driving disc, constitute 5 gear rings that modulus is identical.
