technical field

The invention belongs to the field of electric winches, in particular to a two-speed winch with switchable clutch.

Background technique

At present, in the winches in the existing field, the clutch on the winch reducer is usually in the manual clutch mode. Generally, when the winch is in the field for rescue, if it encounters a harsh environment, a wireless remote control is usually used to control the winch's rope-in and rope-out work. At this time, the clutch needs to be turned on to start the winch. At present, the winches on the market basically use the manual clutch to turn on or off the clutch, which means that when the winch is turned on, it is necessary to go to the side of the winch to manually operate the clutch, which is not very convenient to use. . With the electric clutch, you can control the opening or closing of the clutch through the wireless remote control, and then continue to send instructions to the remote control to control the rotation of the winch; it is very popular to use the wireless remote control to control the winch abroad, but the wireless remote control will There is the same frequency interference problem, and sometimes the remote control cannot control the winch. At this time, this new winch still retains the original manual clutch mechanical structure, and the manual clutch can be used to control the opening or closing of the winch; The process is generally slow, and sometimes the situation is more urgent and it is necessary to quickly withdraw the rope and leave the use environment. Present winch all is to adopt a kind of speed ratio to work, and designing a winch that can switch between fast and slow speed can be said to have very big improvement to winch retracting and unwinding rope.

Turn the clutch on or off.

Preferably, the surface of the cam is provided with a side one, and the cam moves between the first stop ring and the second stop ring, and when the side one is parallel to the surface of the first stop ring perpendicular to the hexagonal transmission rod , at this time the cam is in the initial position, the side one and the surface of the first retaining ring are attached to each other, the cam will withstand the first-stage sun gear assembly, and the first-stage sun gear assembly is provided with a first-stage sun gear, at this time The first-stage sun gear will be fully meshed with the first-stage planetary gear; the first motor starts to rotate, driving the cam to rotate, and when the side one is parallel to the horizontal plane and the side one is above the side two, the cam is in the second position; During the process of the cam rotating from the initial position to the second position, the cam will push the second retaining ring; the second retaining ring will drive the first-stage sun gear to break away from the first-stage planetary gear.

Through the rotation of the first motor, the cam will move to form the initial position and the second position, and the cam will push the first stop ring and the second stop ring, so that the primary sun gear assembly can also maintain the initial position and the second position. At the same time, through the cam to withstand the surface of the first retaining ring or the second retaining ring, the first-stage sun gear assembly can be kept in a fixed state at both the initial position and the second position, so that the first-stage sun gear and The first-stage planetary gear meshes better, and the meshing process remains stable at the same time, so that the speed reducer can be switched between fast and slow.

As a preference, the cam is provided with a circular groove, and there is a cylindrical magnet in the circular groove; the magnet is used to sense the first Hall switch located on the surface of the first motor, the first The front of the motor is provided with two first Hall switches of the same specification and model, one of which is located directly above the central motor shaft, and the other Hall switch is positioned on the center motor shaft as the rotation axis, and is located on the positive side of the motor shaft by counterclockwise rotation.
