The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
A kind of clutch can blank, as shown in figure 1, its structure is respectively the first circular shaft 2 for being used to process screw thread from top to bottom,
The second circular shaft 3 and housing 1 for processing spline, the first circular shaft 2 and the second circular shaft 3 collectively form output shaft.The He of first circular shaft 2
Connected by the first rib between second circular shaft 3, the first rib is shaped as round platform 4, the circular shaft 2 of round platform 4 and first and
Joint angle between the circular shaft 3 of round platform 4 and second is disposed as fillet, and dispersive stress is carried out with this, reduces stress concentration point.
Connected between second circular shaft 3 and housing 1 by the second rib, the second rib is uniformly to be set within one week along output shaft
The 8 spiral shape support beams 5 put（What deserves to be explained is, spiral shape support beam 5 can be in any amount, the present embodiment preferably
For 8）, two sides of spiral shape support beam 5 are connected with the side wall of the second circular shaft 3 and the upper surface of housing 1 respectively, spiral shape
The height of support beam 5 at the second circular shaft 3 to constantly reducing at the upper surface of housing 1, the circular shaft 3 of spiral shape support beam 5 and second it
Between angle and spiral shape support beam 5 and the upper surface of housing 1 between angle be set to fillet.Spiral shape support beam 5 and second
It is integrally formed between circular shaft 3 and housing 1, the bonding strength between such component is big, it is not easy to produces internal flaw and drops
Low-intensity causes fracture.
The outer surface of housing 1 from the connection end of the circular shaft 3 of housing 1 and second to the openend of housing 1 provided with 3 force-bearing tables 11 and
Corresponding 3 vertical planes 12, first force-bearing table 11 is about 90 °, second relative to angle formed by vertical plane 12 from top to bottom
The angle of individual force-bearing table 11 and the 3rd force-bearing table 11 and vertical plane 12 increases successively, turning between force-bearing table 11 and vertical plane 12
Angle is set to fillet.The inner chamber of housing 1 is sequentially provided with open slot 71 and inside groove 72, the wall of inside groove 72 and is respectively equipped with from outside to inside
Bottom surface 81 and inclined-plane 82, between bottom surface 81 and inclined-plane 82 and the wall of inclined-plane 82 and open slot 71 is connected by cambered surface respectively, are opened
Section of the mouth groove 71 along centerline direction is isosceles trapezoid larger at opening.
It is provided with one week logical outside 10 communication with cavity and housing 1 around housing at the opening of open slot 71 on housing 1
Hole 6（What deserves to be explained is, in actual processing, in the case that structural strength allows, through hole can be any amount and position,
The present embodiment is preferably 10）, the diameter of the through hole 6 constantly increases from close to inner chamber side to close to the outside side of housing 1.
, it is necessary to fix the first circular shaft 2 with fixture when being finished to clutch can blank, the second circular shaft 3 or shell
A portion or two parts in body 1, fixture drive fixed part rotation, and fixed part is transferred torque to surplus by rotation
Remaining part is divided and drives its high-speed rotation, and junction during rotation between three parts occurs disconnected by larger shearing force, easily
Split.In the present embodiment, the connection strengthened between the first circular shaft 2 and the second circular shaft 3 by the connection of round platform 4 between the two is strong
Degree.The emphasis of finishing is the processing to housing 1, so stress is than larger, the company between the second circular shaft 3 and housing 1 on housing 1
The place of connecing is more prone to be broken, so junction of the present embodiment between the second circular shaft 3 and housing 1 is supported provided with spiral shape
Beam 5, the spiral shape support beam being uniformly arranged has following effect, first, the side wall of the spiral shape support beam and output shaft and

Keep coaxial relation between the two；Secondly, the spiral shape support beam increases contact area between output shaft and housing, rear
Clutch can blank is conducive to the transmission of torque in continuous process in the case of rotating at a high speed；Finally, if being exported when rotating at a high speed
Junction shearing force between axle and housing is excessive, and the spiral shape support beam 5 can start to be destroyed at first, can select to portion
Divide the support beam of destruction to be cut off and keep remaining part, be unlikely to directly to destroy circular shaft and discard whole clutch can.
Meanwhile, the setting of fillet can effectively dissipate power, prevent the stress concentration of part junction, further improve intensity.
When fixture needs to be clipped on housing 1, force-bearing table 11 can provide fixed station for following process process, make clutch can hair
Base is stable.Force-bearing table 11 and angle formed by vertical plane 12 are a right angle and two obtuse angles, and such setting can be follow-up
To helping to dissipate power in the process of inner chamber, stress concentration is reduced.Cambered surface connection can reduce follow-up internal in the setting of inner chamber
It is larger at stress concentration when chamber is processed, the opening of open slot 71, be conducive to increasing activity space of the process tool in inner chamber.
Clutch can produce amount of heat with steel ball and retainer friction in use, and the one side of through hole 6 can subtract
The contact surface that small clutch can rubs with steel ball and retainer, reduces the generation of heat, while can maintain the circulation of air heat
Outwards transmission, reaches the effect of radiating.The diameter of through hole 6 constantly increases from close to inner chamber one end to close to the outside one end of housing 1,
During so that air is from through hole 6 into inner chamber, air velocity increase, temperature reduction, so as to also reach the effect for making inner chamber cool.
