Description
Technical field
It the utility model is related to the improvement of speed regulator, and in particular to a kind of centrifugal governor.
Background technology
The core component of pneumatic tool is gas motor, and compressed air is done work by gas motor, to drive corresponding part to enter
Row such as is polished, cut, tightening, drilling at the operation.Exported during the half for reaching instrument idle running maximum (top) speed during load operation in theory
Power is maximum, now the operating efficiency highest of instrument, particularly with significant for Pneumatic grinding machine.But traditional pneumatically beats
There is the defects of obvious in grinding machine, because being hand-held tool, the size of working load is to be controlled to adjust by operator, works as load
The rotating speed of gas motor can reduce rapidly during increasing, cause the decline of operating efficiency, although the rotating speed of gas motor on the contrary can rise,
The power of gas motor can decline on the contrary, again result in the decline of operating efficiency.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of centrifugal governor.It
The matching of energy adjust automatically gas motor rotary speed and working load, can be adapted to different size, the gas motor of different capacity, improve gas
The operating efficiency of motor.
To achieve the above object, the utility model is using following technical scheme：It includes speed regulator frame 1, regulator pin
2nd, speed regulator counterweight 3, needle roller pin 5, Speed regulator valve 6, spring base 7, governor spring 8, speed regulator 1 is cross structure, in speed governing
Liquid needle pin 5 is set at the right center of device frame 1, and the right side of speed regulator frame 1 passes through Speed regulator valve 6, and spring base 7 is arranged on speed regulator
The outside of valve 6, the left side of spring base 7 are provided with governor spring 8, speed regulator counterweight are provided between Speed regulator valve 6 and speed regulator frame 1
3, regulator pin 2 passes through speed regulator counterweight 3.
The left side of described speed regulator frame 1 is provided with external screw thread.For connecting gas motor 9.
The screw thread of described speed regulator frame 1 and motor rotor is left hand thread.Prevent speed regulator pine when gas motor 9 operates
Move, fly out.
Described Speed regulator valve 6 is T-shaped sleeve.
Adjust pad 4 is provided between described governor spring 8 and spring base 7.The stress of spring base 7 can be reduced,
The spring force of governor spring 8 can be adjusted.
Operation principle of the present utility model：Governor assembly is rigidly connected with gas motor by screw thread, when gas motor 9 rotates
When governor assembly can be driven to rotate, with the increase of rotating speed, speed regulator counterweight 3 can progressively open under the influence of centrifugal force,
Simultaneously compress governor spring 8, increase spring force, when spring force increase to a certain extent, entering for speed regulator counterweight 3 can be restricted
One step is opened, and now reaches balance, keeps the rotating speed of stable gas motor 9.Conversely, when the rotating speed of gas motor 9 declines, centrifugal force
Reduce, speed regulator counterweight 3 will shrink, cause the reduction of the spring force of governor spring 8, can equally reach balance, also keep
The rotating speed of stable gas motor 9.The quantity and thickness of adjust pad 4 are controlled, that is, controls the spring force of governor spring 8, control
The spring force of governor spring 8 also just controls the rotating speed of gas motor 9.
After adopting the above technical scheme, the utility model has the beneficial effect that：It can adjust automatically gas motor rotary speed and operation
The matching of load, different size can be adapted to, the gas motor of different capacity, improve operating efficiency.
