Abstract
The utility model discloses a locking device of the transmission shaft of a master controller. The locking device is a constituent part of the master controllers of the control devices of a crane and other mechanical equipment. The newly-designed locking device resolves problems of installation and adjustment of the transmission shaft of the master controller in order to overcomes defects existing in a product in the prior art so as to guarantee stable and reliable operation of the transmission shaft. The locking device comprises a handle, a support, a transmission shaft, and locking device assemblies. Each locking device assembly comprises a supporting shaft, a spring gasket, and a locking screw nut. The supporting shaft comprises a cylinder segment and thread segment. The cylinder segment is inserted into a hole on the end socket of the transmission shaft, while the thread segment is screwed in a threaded hole on the support. Two ends of the transmission shaft are equipped with a locking device assembly, respectively. The supporting shafts are rotated and the position of the transmission shaft is adjusted until a requirement is satisfied. And then the spring gaskets and the locking screw nuts are mounted on the exposed segments of the supporting shafts to fix the supporting shafts. Movable fit is achieved between the transmission shaft and the supporting shafts. When the transmission shaft rotates, the supporting shafts are fixed. The locking device is used for producing the master controller of the control device of mechanical equipment.
Description
Technical field:
The utility model relates to the control device of crane and other plant equipment, particularly crane controller master controller, specifically a kind of master controller power transmission shaft locking device.
Background technology:
Existing power transmission shaft be be installed in the master controller support on back shaft be fixedly connected with, use nut check.There is following problems in this structure: 1, when the master controller transmission device was worked, back shaft rotated with power transmission shaft, was easy to cause that back shaft is loosening; 2, the nut of fixed support axle is between power transmission shaft and master controller support, and inconvenience is tightened during assembling; 3, the gap between power transmission shaft and the master controller support is difficult for adjusting, and when power transmission shaft rotated, nut and the mutual friction of support phase caused hold-down nut loosening easily, cause back shaft to produce displacement, make the stuck cisco unity malfunction of power transmission shaft.In sum, there is major defect in existing structure, inadaptable demand of producing.
Summary of the invention:
For many defectives that prior art exists, the utility model provides a kind of new master controller power transmission shaft locking device, and rational structure guarantees the reliable and stable work of power transmission shaft by novelty, satisfies industrial demand.
The utility model adopts following technical proposals, master controller power transmission shaft locking device comprises handle, the master controller support, power transmission shaft, also comprise the locking device assembly, described locking device assembly is by back shaft, spring washer and locking nut form, respectively fill a cover at the power transmission shaft two ends, the power transmission shaft two ends are shaped with circular hole, be shaped with screwed hole on the master controller support, back shaft divides cylindrical section and thread segment, its cylindrical section passes the screwed hole on the support and inserts in the hole of rotation axis termination, thread segment is screwed on the support, exsertion part mounting spring packing ring and the locking nut of back shaft.
During assembling, drive shaft cartridge is on back shaft, and back shaft is contained on the support, and power transmission shaft and back shaft are for movingly, and the turn back shaft makes power transmission shaft be in design attitude, fixes afterwards getting final product with spring washer and locking nut.
Compared with the prior art, the utility model has the advantages that: 1, power transmission shaft and back shaft are movingly, and back shaft maintained static when power transmission shaft rotated, and back shaft is fixed on the support with spring washer and locking nut, thereby back shaft is difficult loosening, guarantees that the power transmission shaft working stability is reliable; 2, there is back shaft at the power transmission shaft two ends, and the back shaft threaded adjusting is convenient to adjust the power transmission shaft position; 3, locking nut is positioned at master controller support outside, installation, debugging, easy to maintenance.
Description of drawings:
Accompanying drawing is master controller power transmission shaft locking device structure figure
Among the figure: 1-handle 2-power transmission shaft 3-master controller support 4-back shaft 5-locking nut 6-spring washer
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model, as shown in the figure, master controller power transmission shaft locking device comprises handle 1, power transmission shaft 2, master controller support 3 and locking device assembly, the locking device assembly is comprised of back shaft 4, locking nut 5 and spring washer 6, power transmission shaft 2 two ends respectively fill looper drive shaft two ends and are shaped with circular hole, be shaped with screwed hole on the master controller support, back shaft 4 is made of cylindrical section and thread segment, the cylindrical section diameter is little, and its diameter is consistent with the aperture of power transmission shaft 2 terminations; The thread segment diameter is large, screw-threaded engagement on its screw thread and the master controller support 3, the cylindrical section of back shaft 4 passes and inserts in the stomidium of power transmission shaft 2 from the screwed hole of support 3, the two is for movingly, power transmission shaft 2 is free to rotate, the thread segment of back shaft 4 is screwed in the screwed hole of support 3, and an end of back shaft 4 is in support 3 outsides, and spring washer 6 and locking nut 5 are housed on it.
Handle 1, master controller support 3 are datum in the utility model, and power transmission shaft 2 is added the worker for datum and formed, and back shaft 4 is steelwork, and spring washer 6 and locking nut 5 are standard component.
