Description
Technical field
The utility model relates to a kind of air motors, and in particular to a kind of screw gear type air motor.
Background technique
Air motor is also referred to as air motor, refers to the dress that the pressure energy of compressed air is converted to the mechanical energy of rotation
It sets, generally as the rotating power source of more complicated device or machine.
Currently, the generally existing structural instability of air motor, processing assemble the problems such as difficult, gap is big, pneumatic efficiency is low.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides that a kind of stable structure, machine parts'precise degree be high, processing assembling
Screw gear type air motor actuator convenient, gap control is accurate, pneumatic efficiency is high.
To achieve the above object, the utility model provides a kind of screw gear type air motor, including seal cavity, two
A gear, driving shaft, driven shaft；The seal cavity is fixedly mounted with by upper press cover, shell, lower cover, frictional disk and is integrated, under described
Gland is equipped with gas source interface, can connect with external air source, two gears pass through driving shaft respectively and are mounted on driven shaft
In seal cavity, and two gear intermeshings, described driving shaft one end are stretched out seal cavity and are exported as torque, can be with needs
The equipment of driving is connected；Pressure-air after the entrance expansion work of one end, is discharged out of described seal cavity from the other end
During which low-pressure air converts rotation output for acting by gear, be ultimately transferred to driving shaft as torque output.
Wherein, the tooth-formation of gear is spiral involute；The driving shaft and driven shaft both ends are solid by rolling bearing
In seal cavity, support gear and seal cavity keep radial clearance；Tune is also arranged with outside the driving shaft and driven shaft
Whole circle, the adjustment circle are respectively supported between rolling bearing and gear, and support gear and seal cavity keep axial gap.
The beneficial effects of the utility model are: using the above structure, since the tooth-formation of gear is spiral involute, energy
Enough preferably sufficiently to do work with compressed air, pneumatic efficiency is high, is more energy-saving and environmentally friendly；
Gear is reduced so that gear also can keep reasonable gap with seal cavity in the axial direction simultaneously by adjusting circle
End face contact wear realizes that stable structure, machine parts'precise degree are high, and adjusting circle is directly to be sleeved on driving shaft and driven shaft
, it is assembled simultaneously with driving shaft and driven shaft, processes easy to assembly, high production efficiency, gap control is accurate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment screw gear type air motor.
Fig. 2 is the structural representation that axial radial clearance is kept in the utility model embodiment screw gear type air motor
Figure.
Specific embodiment
As shown in Figs. 1-2, a kind of screw gear type air motor, including 1, two gear 2 of seal cavity, driving shaft 6, from
Moving axis 3；The seal cavity 1 is fixedly mounted with and is integrated by upper press cover 11, shell 12, lower cover 14, frictional disk 13, the lower cover 14
Be equipped with gas source interface 15, can connect with external air source, two gears 2 by flat key be radially fixedly mounted with respectively driving shaft 6 with it is driven
On axis 3, shown driving shaft 6 is mounted in seal cavity 1 with driven shaft 3, is intermeshed two gears 2,3 axis one of active
End is stretched out seal cavity 1 and is exported as torque, can be connected with the equipment driven is needed；Pressure-air is from the seal cavity
In 1 after the entrance expansion work of one end, low-pressure air is discharged from the other end, it is defeated during which to convert rotation for acting by gear 2
Out, driving shaft 6 is ultimately transferred to as torque output.
Wherein, the tooth form of the gear 2 is spiral involute, preferably can sufficiently do work, will compress with compressed air
The expansion work of air is converted into rotation output, and pneumatic efficiency is high, is more energy-saving and environmentally friendly；
The driving shaft 6 is packed in seal cavity 1 with 3 both ends of driven shaft by rolling bearing 4, supports gear 2 in diameter
Reasonable radial clearance 7 is kept with seal cavity 1 upwards；Adjustment circle 5 is also arranged with outside the driving shaft 6 and driven shaft 3, it is described
Adjustment circle 5 is respectively supported between rolling bearing 4 and gear 2, and support gear 2 keeps reasonable axis in axial direction and seal cavity 1
To gap 8.
Simultaneously by adjusting circle 5, so that gear 2 can also keep reasonable gap with seal cavity 1 in the axial direction, tooth is reduced
Take turns 2 end face contact wears, realize that stable structure, machine parts'precise degree are high, and adjust circle 5 be directly be sleeved on driving shaft 6 and from
It on moving axis 3, is assembled simultaneously with driving shaft 6 and driven shaft 3, processing assembles very convenient, high production efficiency, gap control essence
Really.
