Mounting holes 53 are formed in the facing end surfaces of the first half cover 51 and the second half cover 52 independently of each other, and the first half cover 51 and the second half cover 52 are connected by lock bolts provided in the mounting holes 53 (that is, the lock bolts are mounted in the mounting holes 53 to connect the first half cover 51 and the second half cover 52).
In the present embodiment, the second tooth grooves 54 are provided with guide grooves 55 penetrating therethrough, that is, the guide grooves 55 penetrate all the single teeth of the second tooth grooves 54 parallel to the axial line of the cover 5, so that the flow of the silicone oil between the tooth grooves can be accelerated.
Example 2
The silicone oil clutch shown in fig. 2, which has the spline structure of embodiment 1, further comprises a drive shaft 1 and a cover assembly.
Wherein, the diameter of the driving shaft 1 is reduced from one end to the other end in the axial lead direction, so that a plurality of steps (which can be used for installing other parts such as bearings) are formed on the driving shaft 1; one end of which is inserted into the driving plate 4 so that the driving plate 4 is fitted around one end (the end with a smaller diameter, i.e., the outer end) of the driving shaft 1. In the present embodiment, the driving plate 4 and the driving shaft 1 are fixedly connected by a conventional fastening member such as a spline, so that the driving plate 4 rotates synchronously when the driving shaft 1 rotates.
The cover body component mainly comprises a bearing 2, a shell 3, a driven plate 6, a valve plate 8, a coil assembly 10 and the like. The shell 3 is rotatably sleeved on the driving shaft 1 through the first bearing 2, so that the rotation of the driving shaft 1 cannot influence the shell 3; moreover, the housing 3 is further matched with the cover 5 (specifically, the housing 3 can be covered on the end face of the cover 5, and the edges of the housing 3 are fixed by riveting, welding and other conventional manners, so that the cover 5 and the housing 3 move synchronously (an accommodating space is formed between the cover 5 and the housing 3, and the driving plate 4 is located in the accommodating space), the driven plate 6 is mounted on the driving plate 4 and faces the cover 5, so that an oil storage chamber 9 is formed between the driving plate 4 and the driven plate 6 (the driven plate 6 is also located in the accommodating space, and the oil return channel 56 is also communicated with the oil storage chamber 9), one end of the valve sheet 8 is mounted on the driving plate 4, and the other end of the valve sheet 8 is matched with the oil outlet 41, when the driving shaft 1 generates magnetic force, the valve sheet 8 can be attracted by magnetic force to shield the oil outlet 41 (i.e. close the oil outlet 41), it can be seen that the valve sheet 8 is also located in the accommodating space and is arranged opposite to the driving shaft 1, the coil assembly 11 is conventional, the valve plate is rotatably sleeved on the driving shaft 1 through a second bearing and used for enabling the driving shaft 1 to generate magnetic force to attract the valve plate 8; the coil assembly 11 does not rotate with the axle shaft 1 (the axle shaft 1 is typically mounted to the engine and powered by it) as it rotates, and in this embodiment the coil assembly 11 is located on one side of the housing 3 (i.e., outside the cover 5 and housing 3)
In this embodiment, the coil assembly 11 has two states of power-on and power-off, when it is in the power-on state, the driving shaft 1 generates magnetic force, the valve plate 8 is attracted by the magnetic force to close the oil outlet 41, the silicone oil returns to the oil storage chamber 9 through the oil return channel 56, and the clutch enters the separation state; when the clutch is in a power-off state, the magnetic force of the driving shaft 1 disappears, the valve plate 8 resets and bounces open, the oil outlet 41 is opened, the silicone oil enters the working cavity 10 through centrifugal force, and the clutch enters a coupling state (which is also the working principle of the silicone oil clutch).
