Abstract
The utility model discloses a kind of transmission device.The transmission device includes main shaft, shaft coupling, clamp spring and stop nut.One end section of main shaft falls the shaft end of triangle for Le, shaft end is equipped with jump-ring slot, opposite side is equipped with screw thread, shaft coupling through hole section falls triangle for Le, the shaft end that shaft coupling strangles triangle with main shaft is clearance fit, and clamp spring is stuck in main shaft jump-ring slot, and stop nut is installed on main shaft, coordinate with clamp spring, make shaft coupling axial restraint.It is small that the utility model is mainly used in the main shaft diameter of axle, and needs to transmit big load occasion, it is transmitted, and load is big, and concentrated stress is small.
Description
Technical field
A kind of drive mechanism is the utility model is related to, particularly a kind of spindle gearing.
Background technology
It is more and more strong to the miniature requirement of top load transmission shaft with the fast development of social economy.Conventional master spindle
Passing power relies primarily on flat key, spline drived or transmits load using friction by being interference fitted.Flat key relies on twoSide FaceAs working face, lean onKeyWith key slot sideExtrudingTransmitting the key of torque, suitable at a high speed or withstanding shocks, varying loadAxis, but its needs splines on axis, can weaken axis intensity, can not adapt to the requirement that small axle diameter main shaft transmits high intensity load,
Similarly spline is also required to fluting so as to reduce main axe intensity, and using enjoyable cooperation, using frictional force, its transmission is unstable, and assembles
During be also easy to produce parts damage.
The content of the invention
Goal of the invention：In view of the above-mentioned problems, overcome above-mentioned deficiency, there is provided a kind of transmission device, main shaft are connected with shaft coupling
Realize that small axle diameter main shaft transmits high intensity load using Lip river triangle is strangled in section.
Technical solution：A kind of transmission device, including main shaft, shaft coupling, clamp spring and stop nut, main shaft are equipped with clamp spring
Groove, screw thread, main-axis end outer contour section fall triangle for Le.Shaft coupling is equipped with connecting hole, boss, matching hole, matching hole
Section falls triangle for Le.The stop nut is engaged with screw thread on main shaft, and shaft coupling coordinates with the end play on main shaft,
Clamp spring is stuck in the jump-ring slot on main shaft, and clamp spring makes shaft coupling axial restraint with stop nut.
Further, the main shaft material is steel alloy.
Further, the shaft coupling material is 40Cr or 42CrMo.
Further, it is 8 that hole number is connected on the shaft coupling, along the circumferential direction uniformly distributed.
Further, the main shaft material is 42CrMo.
The utility model principle：Section is connected using Lip river triangle is strangled with shaft coupling using main shaft, and it is fixed width to strangle Lip river triangle
The figure for the area minimum that curve can be formed, and be made of 3 sections of camber lines, concentration that its is unstressed, realize small axle diameter main shaft biography
Pass high intensity load.
Beneficial effect：Compared with prior art, the utility model has the advantages that：Main shaft and connection are transmitted using Lip river triangle is strangled
Power between axis device, without slotting on main shaft, realizes small axle diameter main shaft and transmits high intensity load.

Fig. 2 is this practicality main shaft schematic three dimensional views.
Fig. 3 is the utility model shaft coupling schematic three dimensional views.
Embodiment
It is below specific embodiment, furthers elucidate the utility model, it should be understood that this embodiment is merely to illustrate this reality
With new rather than limitation the scope of the utility model, after the utility model has been read, those skilled in the art are to this
The modification of the various equivalent forms of utility model falls within the application appended claims limited range.
A kind of transmission device as shown in Figure 1, including main shaft 1, shaft coupling 2, clamp spring 3 and stop nut 4.1 He of main shaft
