Abstract: The present invention relates to a winch clutch and a winch thereof. The winch clutch comprises a first gear ring, a drive motor, a rotary member, a transmission member, a clutching member and an elastic reset member. The clutching member is separably connected to the plurality of clutch portions of the first gear ring to stop the first gear ring. Compared with the prior art, the winch clutch of the present invention uses the drive motor to drive the rotary member to rotate, and achieves connection or separation between the clutching member and the clutch portions on the first gear ring through the transmission member, so as to control the winch to start or stop. Compared with conventional manual clutches, manual operation is not required and operation is convenient in the present invention, completely solving the problem of a failure of a vehicle winch clutch.

Abstract: Disclosed is a brake winch with reverse release and self-locking functions. The brake winch has a housing with first and second side walls, an accommodating space, and an auxiliary bracket part. A rotating disk is screwed in the accommodating space. A main shaft is screwed on one side of the rotating disk in an interlocking manner. A screw adapter is screwed on the second side wall, and includes an inner connection end that is assembled with the main shaft, and its external end has a threaded groove. The axial displacement of a driving screw, which is screwed on the auxiliary bracket, is matched with the difference of forward and reverse rotation to form a screwing transmission or release mode between the stud section and the thread groove. A friction driving mechanism must prompt the drive screw, the clamping plate and the screw adapter to be in a tightly synchronized state.

Abstract: A boat lift that may have a first worm screw operably connected to the drive shaft defining an axis of rotation aligned with the drive shaft and operably contacting a first worm gear, the first worm screw and the first worm gear defines a first lifting stage. The boat lift may also have a second worm screw operably connected to the first worm gear and operably contacts a second worm gear, the second worm screw and the second worm gear defines a second lifting stage. The boat lift may have a tapered roller bearing assembly that operably engages the second worm screw, the tapered roller bearing assembly has a first tapered roller bearing secured at a first location proximate a first end of the second worm screw and a second tapered roller bearing secured at a second location proximate a second opposing end of the second worm screw.

Abstract: A hydraulic torque converter transmission system for a dynamic compactor and the dynamic compactor includes an engine, a hydraulic torque converter, a winch, a transfer case, a gearbox, a transmission case, and a reduction gearbox; the power of the engine is transmitted to the winch by means of the hydraulic torque converter; a part of the power of the engine is transmitted to the hydraulic torque converter through the transfer case, and an other part of the power of the engine is transmitted to a hydraulic pump through the transfer case. An output power is transmitted to the transmission case through the gearbox, and the output power of the transmission case is driven by the reduction gearbox to rotate the winch. An output shaft of the engine is along an X-axis directional arrangement, a winch rotating shaft is arranged along a Y-axis direction.

Abstract: A brake is operationally coupled by gear engagement to an axle of a device, whereby turning on the brake prevents the axle from rotating. Monitoring condition of the brake includes driving the axle of the device in a first rotation direction when the brake has been turned on. The axle of the device is driven in a second rotation direction when the brake has been turned on. A first position angle of the axle of the device, which follows from driving the axle of the device in the first rotation direction, is measured. A second position angle of the axle of the device, which follows from driving the axle of the device in the second rotation direction, is measured. A clearance of the gear engagement of the brake is determined on the basis of a difference of the first and the second position angles.
