Problems solved by technology

[0003] In the existing technology, for the reducer in the electric actuator structure, the debugger uses the traditional wheel and shaft fixed handwheel, which was connected by pins in the past. When manual, it is necessary to turn the handwheel and pull out the pins in a parallel state. , use the groove of the shaft sleeve for positioning, turn the handwheel pin to advance in a vertical state when electric, the effect is unstable, it will be easy to touch and fall off, the electric and manual conversion is inconvenient and will bring problems to the debugger

Abstract

The invention provides a hand wheel switching device which comprises a box, a worm gear, a worm and a hand wheel base. One end of the box is connected with the hand wheel base, the worm gear and the worm are arranged in the box, the worm gear is meshed with the worm, the two ends of the worm are arranged on the box through a connection mechanism, the connection mechanism comprises an oil seal, a check ring and a bearing, the oil seal, the check ring and the barring are sequentially arranged on the box from outside to inside, the connection ends of the hand wheel base and the box form a cavity, two sets of needle bearings are symmetrically disposed in an inner cavity of the hand wheel base, a spacer is arranged between the two needle bearings on one side, a hand wheel shaft is arranged in the inner cavity of the hand wheel base, one end of the hand wheel shaft is connected with a hand wheel, and the worm and the hand wheel shaft are located on the same horizontal line. The device has the advantages that an electric state and a manual state can be conveniently switched by adjusting the hand wheel shaft and the worm to be separated or meshed, and safe work environment is provided for operations of adjustment staff.

Description

[0001] technical field [0002] The invention belongs to the technical field of electric actuators, and in particular relates to a handwheel switching device. Background technique [0003] In the existing technology, for the reducer in the electric actuator structure, the debugger uses the traditional wheel and shaft fixed handwheel, which was connected by pins in the past. When manual, it is necessary to turn the handwheel and pull out the pins in a parallel state. , Use the groove of the shaft sleeve for positioning, turn the handwheel pin to advance in a vertical state when electric, the effect is unstable, it will be easy to touch and fall off, the electric and manual conversion is inconvenient and will bring problems to the debugger. Contents of the invention [0004] The purpose of the present invention is to provide a handwheel switching device with simple structure, convenient operation, convenient switching between manual and electric states and providing a s...
