Abstract
The utility model discloses a multistage speed-reducing multi-rotary hand driving device of a valve, which is provided with a valve nut, and a hollow shaft is arranged outside the valve nut. A big bevel gear is arranged outside the hollow shaft, and the big bevel gear and an active bevel gear form a first level retarding bevel gear pair. The utility model is characterized in that the bevel gear pair is also connected with a gear retarding mechanism which is connected with a hand operating mechanism. The utility model has the advantages of high transmission speed ratio, large output torque, small force needed by opening and closing a valve, small size, reasonable structure, smooth transmission, high flexibility and reliability and wide application range.
Description
Technical field:
The utility model relates to the auxiliary opening/closing mechanism of valve, is the manual opening-closing mechanism of valve, specifically, is a kind of manual driving device of many turning valves.
Background technique:
Many turning valves are widely used machinery valves, existing many turning valves use manual driving device more, these existing many turning valves manual driving devices, generally be to adopt bevel gear pair to make one-level to slow down, its major defect is: manual driving device and coupling mechanism will be subjected to very big drag effect during valve opening and closing, and transmission speed ratio is low, output torque is little, required input power is big, the big heaviness of volume, unreasonable structure, transmission is steady inadequately and dumb, performance is unreliable.Its practical ranges also is a greater impact.
Summary of the invention:
The purpose of this utility model provides that a kind of transmission speed ratio height, output torque are big, required input power is little, volume is little, rational in infrastructure, stable drive, flexibility and reliability new multistage applied widely are slowed down many turning valves manual driving device.
Technical solution of the present utility model is: a kind of new multistage many turning valves manual driving device that slows down, Stem Mut is arranged, Stem Mut is equipped with hollow shaft outward, hollow shaft is equipped with bevel gear wheel outward, bevel gear wheel and drive bevel gear constitute one-level deceleration bevel gear pair, it is characterized in that: bevel gear pair also links with reduction gears mechanism, and reduction gears mechanism is connected with handling mechanism.
The reduction gears mechanism that connects with bevel gear pair described in the utility model has 1～3 grade at least.And have 1 grade to be the cylindrical gear reducer structure in the reduction gears mechanism that bevel gear pair connects.When the reduction gears mechanism behind the bevel gear pair has when multistage, wherein there is 1 grade to be planetary gear reducing mechanism, and connects with bevel gear pair.The input gear that connects with handling mechanism is arranged in the cylindrical gear reducer structure, input gear and the engagement of middle idle wheel, middle idle wheel meshes with driven gear again.Handling mechanism is a handwheel.
The beneficial effects of the utility model are:
1, on the basis of former transmission, increased one or more levels gearing down again, transmission speed ratio increases by 2～4 times;
2, because multi-stage speed-reducing has increased speed ratio, its output torque increases 1～2 times than former manual driving device output torque;
3, opening and closing under the required torque condition of same specification valve, by strengthening the speed ratio of this device, required input power can reduce 1～2 times when the manual operation handwheel opens and closes valve;
4,,, improved this device output torque by strengthening the speed ratio of this device this device being applied under the same moment situation;
5, little, rational in infrastructure, the stable drive of volume, flexibility and reliability;
6, this device is because the output torque scope is wide, and no matter roomy finished product scope makes that this device all can be corresponding with all size valve supporting on the drive mechanism still on the operating efficiency.
