In order to make those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and specifically
The utility model is described in further detail for embodiment.
Referring to FIG. 1, Fig. 1 is the structural schematic diagram of bevel gear provided by the utility model.
The utility model provides a kind of bevel gear, including valve body 1 and the transmission shaft 2 equipped with angular wheel 3, transmission shaft
2 laterally settings, and be sequentially connected with valve body 1；Further include the driving device 8 coaxially connected with transmission shaft 2, when work,
Driving force is provided to valve body 1 by transmission shaft 2 from driving device 8, with the unlatching of control valve and closure；On transmission shaft 2
It is arranged with first bearing 4, second bearing 6 and 3rd bearing 5, wherein first bearing 4 and second bearing 6 are close to conical tooth respectively
The right side of wheel 3 and left side installation, second bearing 6 are close to the installation of first bearing 4, and three bearings cooperate, common to support
Transmission shaft 2 reduces the friction coefficient in 2 transmission process of transmission shaft, improves its rotating accuracy, is operated to promote transmission shaft 2
Stationarity, effectively avoid the driving error in transmission process, and effectively reduce drive noise.
It, can be by transmission shaft 2 to reduce driving error in order to reduce the driving torque between driving device 8 and transmission shaft 2
It is set as eccentric structure with the connection structure of driving device 8, that is, retarder 7 is installed between transmission shaft 2 and driving device 8,
By the Multi-stage transmission between each gear in retarder 7, the rotating speed that can be will be transmitted on 8 output shaft of driving device reduces, and comes
Reduce torque, reduces input power, increase torque, is cost-effective.
Specifically, above-mentioned retarder 7 includes input gear, the first reduction gearing, the second reduction gearing, third reducing gear
Wheel and output gear, wherein input gear connects 8 output shaft of driving device, the first reduction gearing and the second reduction gearing phase
Engagement, the second reduction gearing are coaxially disposed with third reduction gearing, and third reduction gearing is meshed with output gear, output gear
Transmission shaft 2 is connected, by the Multi-stage transmission between the 7 each gear in inside of retarder, to realize that reduction torque, increase torque, reduction are defeated
The purpose for entering power, reducing cost.
In addition, the left end of transmission shaft 2 is installed with angular wheel 3, corresponding, valve body 1 is internally provided with valve gear
9, which is sleeved on valve rod, and is meshed with angular wheel 3, and at work, driving device 8 passes driving force
Retarder 7 is passed, by the Multi-stage transmission between 7 internal gear of retarder, the high rotating speed that driving device 8 exports is converted to low turn
Speed is transferred on transmission shaft 2, since the angular wheel 3 on transmission shaft 2 is meshed with the valve gear 9 inside valve body 1,
Therefore, valve gear 9 is further imparted power to, movement is opened and closed to carry out lifting with movable valve.
In order to realize more drivings operation of bevel gear, improve the working efficiency of bevel gear, electric drive can be further added
