Disclosure of Invention
The utility model aims to solve the technical problem of providing a driving mechanism for a lifting table, which can reduce the situations of accurate installation, difficult abnormal sound or failure and can solve the defects in the prior art.
The technical scheme of the utility model is as follows: the utility model provides a drive mechanism for lift table, contains internally mounted has the lift post of lead screw assembly, and lift post top sets up the inside diversion ware that contains the meshing gear train, and the polygon interface is seted up at diversion ware input gear center, and through the rotatory transfer line of motor drive and the grafting interface grafting cooperation of diversion ware input gear, the transfer line contains the grafting end that the cross-section is the same with the grafting interface and is located the reduction portion in grafting end the place ahead, the reduction portion does not contact with the input gear when getting into the grafting interface of input gear.
Further packing elastic gasket, be equipped with the screw support post on the lift post, the motor passes through the bolt and is installed on the lift post with screw support post connection, elastic gasket cover is located the bolt and is filled up and locate between screw support post and the motor.
Further, an annular groove is arranged on the peripheral wall of the elastic gasket.
The novel transmission rod is characterized by further comprising a sleeve, wherein the sleeve is in threaded connection with a set screw, and the sleeve can be sleeved on the transmission rod and fixed by tightening the set screw.
By implementing the utility model, when the transmission rod is inserted into the gear at the transmission end of the deviator, the transmission rod can be inserted into the transmission rod for a longer distance, but only the insertion end is contacted with the inner wall of the insertion port, the front reduction part is not contacted with the inner wall of the gear insertion port of the input end, the contact area of the transmission rod and the gear insertion port is determined according to the length of the insertion end, the transmission rod and the gear insertion port can be stably connected under the condition of smaller contact area, the installation is precise, and the situation of detachment failure is avoided.
