Abstract
The utility model provides a hand gear for valve used for opening and closing of the valve, which comprises a casing and an input shaft horizontally positioned inside the casing. An inner end of the input shaft is connected with a small bevel gear, and an outer end is connected with a hand wheel. An output shaft is vertically arranged inside the casing. A big bevel gear is connected with the output shaft and engaged with the small bevel gear. The big bevel gear and the small bevel gear are a conical-teeth arc gear respectively. The utility model can remarkably reduce the transmission friction by adopting the conical-teeth arc gear for engaged transmission, has light and convenient transmission of the hand wheel, slowed wear of the gear, stable transmission and further reduced generated noise.
Description
Technical field: the utility model relates to the valve manual operating device that a kind of opening/shutting valve is used.
Background technique: the input shaft of valve manual operating device generally all becomes crisscross with output shaft, utilizes a pair of large and small bevel gear that is meshed to turn to transmission.Because generally with awl tooth spur gear, the friction of engagement driving is bigger for bevel gear, power consumption is more, rotates heavy effort, and gear wear is accelerated, and easily scraps.Simultaneously, the noise that general bevel gear sends at work is big, influences working environment.
Summary of the invention: the utility model is to solve prior art gearing friction and the bigger problem of operating noise, and a kind of friction and the little valve manual operating device of noise are provided.
The utility model comprises housing and is horizontally placed on wherein input shaft, this input shaft inner end connects bevel pinion, and the outer end is connected with handwheel, and output shaft is perpendicular to be placed in the housing, bevel gear wheel is connected on the output shaft and bevel pinion is meshed, and bevel gear wheel and bevel pinion are awl sector gear.
Using awl sector gear to carry out engagement driving can obviously reduce gearing friction, and it is light that handwheel is rotated, and gear wearing and tearing itself are slowed down, and transmission is also steady, and the noise that sends reduces.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is embodiment's a main structure schematic representation.
Embodiment: as shown in the figure, the housing 1 interior horizontal input shaft 2 that has, these input shaft 2 inner ends connect bevel pinion 3, the outer end is connected with handwheel 4, output shaft 5 perpendicular placing in the housing 1, bevel gear wheel 6 is connected on the output shaft 5 and bevel pinion 3 is meshed, and this bevel gear wheel 6 and bevel pinion 3 are awl sector gear.Valve rod with output shaft 5 and valve during use is connected, and rotates handwheel 4 and gets final product opening/shutting valve.The output shaft 5 of present embodiment is a hollow shaft, and the chamber is connected with Stem Mut 7 within it, and convenient the installation connects.
