A shaft locking device for a transmission mechanism

Abstract

The invention discloses a rotating shaft locking device of a transmission mechanism. The rotating shaft locking device comprises a transmission locking device and a locking gear fixedly connected onto a rotating shaft of the transmission mechanism; the transmission locking device comprises a lead screw, a driving motor, a base, a locking block and guide rails which are parallelly fixed on the base; the two sides of the locking block sleeve the guide rails; one end of the locking block is provided with teeth meshed with the locking gear, and the other end of the locking block is connected with the driving motor which is fixed on the base through the lead screw; the driving motor drives the locking block to move along the guide rails to be meshed with the locking gear for locking or to be separated from the locking gear for unlocking through the lead screw; the driving motor is utilized for providing power for the locking block to ensure the insertion and the separation of the teeth; the automatic locking function of the rotating shaft is effectively solved; the locking force can be set by controlling the rotation speed of the driving motor and the backoff amount after locking; the maintenance of a locking load is realized through the self-locking ability of a screw-nut pair; the locking reliability is high; and the assembly is convenient.

Description

technical field [0001] The invention relates to a locking mechanism of electromechanical transmission equipment, in particular to a rotating shaft locking device of a transmission mechanism. Background technique [0002] The shaft locking of existing transmission mechanisms such as turntables mainly relies on the self-locking function of its transmission components, such as the self-locking property of worm gears or electromagnetic clutches. Using worm gears as self-locking mechanisms for rotating shafts requires self-locking of worm gears and worms. The lock function causes the disadvantage of low efficiency of the transmission chain and the high power of the driving motor. Using an electromagnetic clutch as a locking mechanism has the problems of large volume and large magnetic interference of the electromagnet to the work of the precision parts of the turntable. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention pr...
