The first flanging shaft sleeve 3-4-2 together with the bearing 3-4-3 is penetrated through the bracket 3-1 and is fastened and installed with the bracket 3-4 through the fastener 3-4-4.

The transmission shaft 3-4-1 passes through the bearing 3-4-3 from the inside of the bracket 3-1, and a limiting table is arranged on the transmission shaft 3-4-1 to prop against the bearing 3-4-3 so as to prevent the axial movement of the transmission shaft.

Alternatively, the other end of the drive shaft 3-4-1 is provided with a hexagonal hole (tetragonal hole/spline hole, etc. are not limited thereto).

Namely, when the motor 3-2 is electrified to rotate, the transmission shaft 3-4-1 is driven to rotate by the spur gear pair (7) (the pinion 3-3 and the bull gear 3-4-6), and the clutch driving shaft 6-1 and the transmission shaft 3-4-1 simultaneously and coaxially rotate.

Referring to fig. 5, the driven side clamp includes a spline shaft 3-5-1, a retainer ring 3-5-2, a second burring shaft sleeve 3-5-3, and a spring 3-5-4.

The second flanging shaft sleeve 3-5-3 is fixedly arranged on the bracket 3-1 by using a screw.

The second flanging shaft sleeve 3-5-3 is internally provided with a spline hole, and the spline shaft 3-5-1 penetrates through the second flanging shaft sleeve 3-5-3 and is in spline connection with the second flanging shaft sleeve to ensure that the second flanging shaft sleeve and the second flanging shaft sleeve do not rotate relatively radially.

The retainer ring 3-5-2 is sleeved on the spline shaft 3-5-1 to prop against the second flanging shaft sleeve 3-5-3, and the retainer ring 3-5-2 is provided with a retainer ring groove, so that the spline shaft 3-5-1 cannot deviate from the second flanging shaft sleeve 3-5-3.

A spring 3-5-4 is arranged between the end part of the spline shaft 3-5-1 and the inner side of the bracket 3-1, the spring 3-5-4 is sleeved on the spline shaft 3-5-1, one end of the spring 3-5-4 is propped against the bracket 3-1, and the other end is propped against the end part of the spline shaft 3-5-1.

The end of the spline shaft 3-5-1 is fixedly connected with the clutch driven shaft 6-2, and optionally, the end of the spline shaft 3-5-1 is provided with a hexagonal hole (tetragonal hole/spline hole, etc. are not limited to), so that the clutch driven shaft 6-2 does not rotate relative to the spline shaft 3-5-1 of the driven side clamp 3-5 and the bracket 3-1. Meanwhile, the end part of the spline shaft 3-5-1 is of a clamping structure, an object to be clamped, namely a clutch driven side shaft, can be further clamped through screw fastening so that the object to be clamped cannot rotate relative to the spline shaft 3-5-1, and optionally, the axial section of the spline shaft 3-5-1 is T-shaped.

The spline shaft 3-5-1 can be axially moved relative to the bracket 3-1 by compressing or releasing the springs 3-5-4.

The other side of the bracket 3-1 is provided with a driven side clamp 3-5.

Referring to fig. 6, a method of assembling a clutch break-in device: when the clutch is installed, the spline shaft 3-5-1 is axially compressed along the Y-axis to compress the spring 3-5-4 so as to leave a clutch installation position, and the clutch driving shaft 6-1 is inserted into a hexagonal hole (a square hole/spline hole and the like are not limited) of the transmission shaft 3-4-1 of the driving side clamp 3-4 to be fixedly connected. The spring 3-5-4 moves along the axial direction of the-Y axis from reset, the clutch driven shaft 6-2 is inserted into a hexagonal hole (a square hole/a spline hole and the like are not limited to) at the end part of the spline shaft 3-5-1 of the driven side clamp 3-5 to be fixedly connected, and meanwhile, the clutch driven shaft 6-2 is clamped through the end part of the spline shaft 3-5-1 so that the clutch driven shaft 6-2 cannot rotate relative to the spline shaft 3-5-1. The restoring force of the spring 3-5-4 enables the spline shaft 3-5-1 and the transmission shaft 3-4-1 to simultaneously support against the clutch.

The working principle of the clutch running-in device is as follows: when the motor 3-2 is electrified to rotate, the transmission shaft 3-4-1 is driven to rotate through the spur gear pair (7) (the pinion 3-3 and the bull gear 3-4-6), and the clutch driving shaft 6-1 and the transmission shaft 3-4-1 simultaneously and coaxially rotate. The clutch driven shaft 6-2 is fixed to the driven side jig 3-5 without relative movement to the bracket 3-1. Namely, the clutch driving shaft 6-1 is driven to rotate, and the clutch driven shaft 6-2 is fixed. When the driving force transmitted to the clutch driving shaft 6-1 by the motor 3-2 is larger than the clutch slip force, the clutch slips, so that the running-in of the clutch is realized.

Referring to fig. 7, a method of controlling a clutch running-in apparatus. The delay relay and the contactor serve as main control elements, namely a control assembly. The clutch running-in device is automatically controlled by the following secondary control logic.

The motor loop and the control loop are connected in parallel at two ends of the power supply. The power supply is electrically connected with the motor 3-2 through the rectifying block 5, so that the device can use an alternating current/direct current motor as a power source.

The control loop uses a time delay relay and a contactor as the main control elements, i.e. the control assembly. The control assembly comprises contactors KM1, KM2 and KM3, and delay relays KT1, KT2, KT3 and KT4.

When the starting button SB1 is pressed, the air switch QF1 is closed, the forward rotation loop is connected, the coil of the contactor KM1 is excited, and normally open contacts 1-2 and 3-4 of the contactor KM1 are closed, so that the motor rotates forward to grind the clutch. When a start button SB1 is pressed, a delay relay KT1 which is connected in a forward rotation loop is started at the same time, wherein the delay relay KT1 is started after 1 minute, namely a normally closed contact (15-16) which is connected in the forward rotation loop in series is disconnected after 1 minute, the forward rotation loop is cut off, a contactor KM1 coil and a KT1 delay relay coil lose magnetism, normally open contacts (1-2) and (3-4) which are connected in series in a motor loop of the contactor KM1 are recovered, the motor loop is powered off, the motor stops rotating, and the forward rotation running-in of a clutch is stopped;

When the delay relay KT2 is started after 10 seconds, the normally open contact (25-28) of the KT2 serial reversing loop is closed and opened instantaneously, a pulse signal is sent out, the reversing loop is connected, the contactor KM3 coil of the reversing loop and the delay relay KT3 coil are excited, normally open contacts (1-2) and (3-4) of the KM3 contactor are closed, and the motor is reversed to carry out reversing running-in on the clutch. The delay relay KT3 is started after 1 minute, namely a normally closed contact (15-16) of the reverse loop is disconnected after 1 minute, the reverse loop is cut off, so that the coil of the contactor KM3 is demagnetized, normally open contacts 1-2 and 3-4 of the contactor KM3, which are connected into the motor loop in series, are restored to be normally open, the motor loop is powered off, the motor stops rotating, and reverse running-in of the clutch is stopped;

When the KT3 delay relay is started after 1 minute, normally open contacts (25-28) which are connected in series into an alarm loop are closed, are closed and opened instantaneously, and send out a pulse signal to switch on the alarm loop, so that the delay relay KT4 of the alarm loop is excited, and meanwhile, a buzzer is started to alarm, and whistle is used for indicating the end of the whole running-in action. The delay relay KT4 is started after 5 seconds, the normally closed contact (15-16) of the delay relay KT4 which is connected in series with the alarm loop is disconnected, and the buzzer stops alarming.

The normal rotation break-in loop contactor KM1, the intermittent loop contactor KM2 and the reverse rotation break-in loop contactor KM3 are respectively provided with a pair of normally open points which are integrated with an indication loop, and an indication lamp is introduced into the indication loop. The clutch indicates that the loop is closed during the whole running-in action, and the indicator lights are turned on.

An interlock microswitch SP and a scram button SB are connected in series in the main circuit. The interlock micro switch SP is switched by means of the opening and closing actions of the hatch 2, and when the hatch 2 is opened, the interlock micro switch SP opens the main circuit so that the running-in action is stopped. So as to prevent safety accidents caused by the fact that someone else enters the grinding machine in the running-in process. When the scram button SB is pressed, the running-in operation can be stopped at any time.
