Abstract

The utility model discloses a multi-turn gear case reducer for a gate valve and a stop valve switch. The multi-turn gear case reducer is characterized in that one input can drive multiple outputs and comprises a gear case, an input shaft and a transmission gear which is arranged in the gear case and is in transmission connection with the input shaft; and the input shaft is in transmission connection with a plurality of output shafts through the transmission gear. Because a plurality of output shafts are installed, during the work process, the input shaft inputs torque, the torque is transmitted to a plurality of output shafts through the transmission gear and the output shafts open and close a plurality of valves at the same time; and the multi-turn gear case reducer is specially applicable to a diversion gate switch of a rural water channel, such as the opening or closing of a plurality of gates of a small reservoir or the water channel.

Description

Many rotary gear boxes retarder

Technical field

The utility model relates to a kind of speed reducer structure, is specifically related to a kind of many rotary gear boxes retarder that is used for gate valve, stop valve switch.

Background technique

At present, the existing many rotary gear boxes retarder in market has only an input shaft and an output shaft, as Fig. 1 and shown in Figure 2.Many rotary gear boxes retarder like this can be used for gate valve, stop valve open and close actuator, be convenient to the switch of valve, but the purposes scope is narrower.The groundwork principle is: obtain an input motion and torque from input shaft A, through a pair of umbrella gear reinforcement (comprising bevel pinion on the input shaft A and the large bevel gear on the output shaft D), pass to cloudy nut by the coupling on the gamp tooth, cloudy nut is rotated, thus output movement and torque.When cloudy nut rotates, move up and down, can realize the unlatching of valve or close by the thread belt movable wire bar on the cloudy nut.

The model utility content

Technical problem to be solved in the utility model provides and a kind ofly realizes an input and drive many rotary gear boxes retarder of a plurality of outputs.

The technological scheme that its technical problem that solves the utility model adopts is: many rotary gear boxes retarder, comprise gear-box, input shaft and the driving gear that is positioned at gear-box and is in transmission connection with input shaft, described input shaft is connected with many output shafts by driving gear.

As optimized technical scheme, the described driving gear that is arranged in the gear-box adopts large bevel gear, output terminal at input shaft is provided with the input shaft bevel pinion, input end at output shaft is provided with the output shaft bevel pinion, and described input shaft bevel pinion and output shaft bevel pinion all mesh with large bevel gear.

Further be in large bevel gear, to be set with cloudy nut.

The beneficial effects of the utility model are: owing to be provided with many output shafts, during work, by the input shaft input torque, pass to many output shafts through driving gear, realize simultaneously the keying of a plurality of valves is operated by many output shafts then, be specially adapted to rural area water channel diversion gate switch, as the unlatching of a plurality of gates of small reservoir or water channel or close.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Extremely shown in Figure 7 as Fig. 3, many rotary gear boxes retarder of the present utility model, comprise gear-box 1, input shaft 2 and the driving gear 4 that is positioned at gear-box 1 and is in transmission connection with input shaft 2, described input shaft 2 is connected with many output shafts 3 by driving gear 4.Owing to be provided with many output shafts 3, when then working,, pass to many output shafts 3 through driving gear 4 by input shaft 2 input torques, realize simultaneously the keying of a plurality of valves is operated by many output shafts 3 then.

In the above-described embodiment, driving gear 4 can adopt spur gear, helical gear type of belt drive to realize, as the preferred construction form, as shown in Figure 6, the described driving gear 4 that is arranged in the gear-box 1 adopts large bevel gear, output terminal at input shaft 2 is provided with input shaft bevel pinion 5, is provided with output shaft bevel pinion 6 at the input end of output shaft 3, and described input shaft bevel pinion 5 all meshes with large bevel gear with output shaft bevel pinion 6.During work, input shaft 2 input torques pass to large bevel gear by input shaft bevel pinion 5, drive a plurality of output shaft bevel pinions 6 by large bevel gear then and rotate, and rotate thereby realize driving many output shafts 3, realize the keying operation to a plurality of valves; Angle between input shaft 2 and the output shaft 3 can change arbitrarily, to realize that a plurality of valves of different setting types are opened and closed operation.In this embodiment, can directly on many output shafts 3, screw thread be set, driving leading screw rotates and the keying operation of realization valve, also can adopt structure as shown in Figure 5, at output shaft 3 ends gear-box is set again, large bevel gear is set in gear-box then equally, be provided with in large bevel gear that thread belt movable wire thick stick rotates and realize keying valve, also can be on Fig. 3 architecture basics, on output shaft 3 terminal large bevel gears, mesh a plurality of bevel pinions (many output shafts more promptly are in transmission connection) again and realize keying operation more valves.In the above-described embodiment, can be in large bevel gear package packing rotating shaft drive that screw mandrel rotates and the keying that realizes valve as preferred mode, is set with cloudy nut 7 in large bevel gear.Rotate the keying that realizes valve by the thread belt movable wire thick stick in the cloudy nut 7, can make structure more compact.
