Technical solutions of the utility model: a kind of control sleeve applied to gearbox, including sleeve body, the sleeve sheet
Body includes upper surface and lower end surface, and the sleeve body inner wall uniform intervals are provided with multiple circular arc types and draw oil groove, multiple described
Drawing oil groove is that upper surface is extended along inner wall, and the lower end surface bottom is provided with elongated end, and the elongated end is around lower end surface
Bottom is formed for one week, and it is 2 to 3 millimeters that the elongated end is extended compared with lower end surface outer wall dimension, the elongated end and sleeve sheet
It is provided with outer chamfer between internal wall, is arranged on the upper surface along for fillet.
By adopting the above technical scheme, the drawing oil groove design of control sleeve is by being put into mold and passing through after high frequency stove heating
It squeezes what drawing pulled out slot, outer chamfer is provided between elongated end and sleeve body inner wall, run action is easier to be bonded
Transmission internal, as to be rotated up and down movement, the control sleeve precision designed in this way is high, and has and draw oil groove design, easily
Oil inlet is provided, realizes the lubricant effect of control sleeve.
The further setting of the utility model: the drawing oil groove includes long drawing oil groove and short drawing oil groove, the long drawing oil groove
Length be set as 18 millimeters, the short drawing oil groove is sized to 9 millimeters.
By adopting the above technical scheme, the long length for drawing oil groove is set as 18 millimeters and short drawing oil groove is sized to 9 millis
Rice, the application size effect as drawing oil groove are best.
The further setting of the utility model: the long drawing oil groove and the setting of short drawing oil groove interval.
By adopting the above technical scheme, interval setting is long draws oil groove and short drawing oil groove to greatly strengthen oil inlet and lubricant effect.
The further setting of the utility model: concave radius is set as 2.5 millimeters under the drawing oil groove.
By adopting the above technical scheme, concave radius under oil groove is drawn to be set as 2.5 millimeters, as the application size effect for drawing oil groove
Most preferably.
The further setting of the utility model: it is 2.5 millimeters that the elongated end is extended compared with lower end surface outer wall dimension.
By adopting the above technical scheme, it is 2.5 millimeters that elongated end is extended compared with lower end surface outer wall dimension, it is easier to which fitting becomes
Inside fast case.
The further setting of the utility model: the sleeve body diameter is set as 32 millimeters.
By adopting the above technical scheme, sleeve body diameter is set as 32 millimeters, the application size effect as control sleeve
Most preferably.
The further setting of the utility model: the outer chamfer angle being arranged between the elongated end and sleeve body inner wall is
45 degree.
By adopting the above technical scheme, 45 angles being outside one's consideration between chamfer angle design elongated end and sleeve body inner wall are easier to
In fitting transmission internal.
Detailed description of the invention
Attached drawing 1 is the utility model specific embodiment overall structure figure.
Specific embodiment
A kind of control sleeve applied to gearbox as shown in Figure 1, including sleeve body 1, the sleeve body 1 include
Upper surface 2 and lower end surface 3, the 1 inner wall uniform intervals of sleeve body are provided with multiple circular arc types and draw oil groove 4, multiple drawings
Oil groove 4 is that upper surface 2 is extended along inner wall, and 3 bottom of lower end surface is provided with elongated end 5, and the elongated end 5 is around lower end
3 bottom of face one week is formed, and it is 2 to 3 millimeters that the elongated end 5 is extended compared with 3 outer wall dimension of lower end surface, the elongated end 5 with
It is provided with outer chamfer between 1 inner wall of sleeve body, is arranged on the upper surface 2 along for fillet.
The design of drawing oil groove 4 of control sleeve is to be pulled out slot by squeezing drawing by after high frequency stove heating, being put into mold
, outer chamfer is provided between 1 inner wall of elongated end 5 and sleeve body, run action is easier to fitting transmission internal, as
To be rotated up and down movement, the control sleeve precision designed in this way is high, and has and oil groove 4 is drawn to design, and control is realized in easily offer oil inlet
The lubricant effect of sleeve processed.
The drawing oil groove 4 includes long drawing oil groove 6 and short drawing oil groove 7, and the long length for drawing oil groove 6 is set as 18 millimeters,
The short drawing oil groove 7 is sized to 9 millimeters.
The long length for drawing oil groove 6 is set as 18 millimeters and short drawing oil groove 7 is sized to 9 millimeters, as drawing oil groove 4
It is best using size effect.
The long drawing oil groove 6 and the setting of short drawing oil groove 7 interval.
Interval setting is long to draw oil groove 6 and short drawing oil groove 7 to greatly strengthen oil inlet and lubricant effect.
The lower concave radius of the drawing oil groove 4 is set as 2.5 millimeters.
The lower concave radius of oil groove 4 is drawn to be set as 2.5 millimeters, the application size effect as drawing oil groove 4 is best.
