Description
Technical field
The utility model is related to machinery production equipment technical field, specifically a kind of agricultural machinery countershaft.
Background technology
Countershaft is the part commonly used in being driven, and the effect of variable-speed torque-converting, countershaft one can be produced by different gear combinations
As include wheel rim, rotating shaft, the taper surface of wheel rim is provided with cone tooth, and drive bevel gear is doing rotation at a high speed always during due to work,
And coordinate with other gear drives, so, fixture and positioning datum really fixed output quota when this to processing higher for required precision
Requirement higher is given birth to.Especially when countershaft is processed, it is necessary to clamping repeatedly, rotating shaft axiality cannot be protected when causing processing
Card, can produce larger vibrations during rotation, make a noise, the life-span of influence drive bevel gear and the parts coordinated with it, secondary
The structure type of axle is varied, and species is various, as a kind of common power transmission mode, is widely used in production, life
Every field in work.
Due to being made using ferrous materials more than countershaft, cause gear more heavy, when the screw rod of gear rotates to one
Determine degree, be just difficult to rotate, gear is installed insecure, and using lathe in machining screw thread and gear-hobbing machine rolling involute flower
Key, operation is more, in existing mechanical transmission course, situations such as easily there is gear loose, because torsion is excessive, causes wheel
Axle portion is deformed, and influence equipment is normally run, and the productivity effect of enterprise is so just reduced unconsciously, therefore we are to this
Make improvement.
Utility model content
The technical problems to be solved in the utility model is the defect for overcoming prior art, there is provided a kind of agricultural machinery countershaft.
In order to solve the above technical problems, the utility model provides following technical scheme：A kind of agricultural machinery countershaft, including：Cone
Gear, Step Shaft, axle tail, external splines, bearing construction section and elastic groove, the bevel gear outside are uniformly provided with conical tooth, described
Step Shaft bottom is provided with external splines, and the spline of the external splines is involute spline, and the axle caudal face is provided with external screw thread, and axle
Tail bottom is provided with open slot, and the Step Shaft is provided with transition arc, the bearing construction section and bevel gear with axle tail junction
Installation place is provided with elastic groove.
Further, the front end face of the bevel gear is taper surface, and bevel gear is provided with levoform conical tooth.
Further, the bevel gear and Step Shaft surface are equipped with wearing layer.
Further, the number of teeth of the external splines is 18 teeth to 20 teeth.
The utility model has an advantageous effect in that compared with prior art：
1. the fatigue resistance of bevel gear and Step Shaft is good, long service life；
2. spline thread intensity is high, outward appearance is reasonable；
3. with low cost, using effect is good.
The utility model has the good fatigue resistance of bevel gear and Step Shaft, long service life, spline thread intensity high, outer
The advantages of reasonable, the with low cost, using effect of sight is good.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure marked as：1- bevel gears；2- conical tooths；3- Step Shafts；4- external screw threads；5- axle tails；6- open slots；7- transition
Circular arc；8- external splines；9- bearing construction sections；10- elastic grooves.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
A kind of agricultural machinery countershaft as shown in Figure 1, including：Bevel gear 1, Step Shaft 3, axle tail 5, external splines 8, bearing are installed
Section 9 and elastic groove 10, the outside of the bevel gear 1 are uniformly provided with conical tooth 2, and the bottom of the Step Shaft 3 is provided with external splines 8, described
The spline of external splines 8 is involute spline, and the side of axle tail 5 is provided with external screw thread 4, and the bottom of axle tail 5 is provided with open slot 6,
The Step Shaft 3 is provided with transition arc 7 with the junction of axle tail 5, and the bearing construction section 9 is provided with elasticity with the installation place of bevel gear 1
Groove 10.
The front end face of the bevel gear 1 is taper surface, and bevel gear is provided with levoform conical tooth 2, is easy to improve machinery
Bonding strength；The bevel gear 1 and the surface of Step Shaft 3 are equipped with wearing layer, are easy to stable connection to increase the service life；It is described outer
The number of teeth of spline 8 be 18 teeth to 20 teeth, be easily installed firmly.
Principle of the present utility model and advantage：The utility model discloses a kind of agricultural machinery countershaft, when using, Step Shaft 3
External splines 8 and the junction of axle tail 5 be provided with transition arc 7, when bevel gear 1 by bearing be arranged on agricultural machinery workpiece on, and with quilt
In dynamic angular wheel intermeshing operation process, due between external splines 8 and axle tail 5 by arc transition, so as to by the He of external splines 8
Stress surface between axle tail 5 replaces with arc surface by existing wedge angle, increased the stress surface between external splines 8 and axle tail 5, makes stress
Dispersion, strengthens the fatigue resistance of the Step Shaft 3 of bevel gear 1, makes the Step Shaft 3 of bevel gear 1 not easy to break in operation process, from
And extend the service life of bevel gear 1, bevel gear 1 and the junction of Step Shaft 3 be provided with for strengthen bevel gear and spindle nose it
Between elasticity elastic groove 10, bevel gear 1 work when, the body of bevel gear 1 by drive Step Shaft 3 rotate, due to emergency situations occur,
Step Shaft 3 can be stopped suddenly or rotating speed plunges, and causes to produce very big moment of torsion between bevel gear 1 and Step Shaft 3, if do not had
Buffering, then bevel gear 1 will damage, setting elastic groove 10 can increase deformability therebetween, when preventing rigidity too strong
Bevel gear 1 is damaged, and is tapped its inner side with instrument at open slot 6, protrudes lateral open slot 6 in axle tail 5, due to open slot
6 walls are obliquely installed, so opening is big, axle tail 5 will not be damaged when tapping axle 5 inner side of tail, prevent from influenceing the precision of axle tail 5, save
Set-up time, while anti-loosing effect substantially, is prevented effectively from the situation generation that countershaft fluffs when in use.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
