Description
Technical field
The utility model relates to a kind of power equipment, and more particularly, the utility model relates to a kind of for driving pneumatic vane motor on the equipment such as oil pump, fan, winch and paddle, that have axial bearing capacity.
Background technique
Pneumatic vane motor is a kind of power equipment, and the gas to its input certain pressure blows the rotation of its rotor upper blade, thereby makes motor output speed and moment of torsion.The structure of pneumatic vane motor mainly is made up of rotor and blade, cylinder body, front and rear cover and bearing, axle envelope etc.Rotor is positioned on the front and rear cover by bearing, and end cap is fixedlyed connected with cylinder body with bolt with locating stud.Rotor place in the cylinder body and with cylinder body in circle eccentric, and leave certain clearance between two ends of rotor face and the front and rear cover.Rotor has 4 or 8 grooves vertically, and blade places in the groove and can radially be free to slide and touch inboard wall of cylinder block, forms the chamber of several independent transfigurations between rotor and cylinder body.Cylinder body is provided with porting and air flue, the cavity that pressurized gas is separated by blade by suction port and air flue entering part during motor operations, owing to had pressure difference between the cavity, so pressurized gas has promoted blade, the drive rotor rotates, thereby makes motor output speed and moment of torsion.Along with the rotation of rotor, cavity volume produces from large to small, from and the gas in the cavity discharged by relief opening.Pneumatic vane motor can smooth and easyly rotate in order to make rotor, must guarantee to leave rational gap between the both ends of the surface of rotor and the end cap.Excesssive gap then makes the cavity gas blowby cause decrease in efficiency.The inhomogeneous rotor end-face that then might occur in two ends of rotor gap contacts with end cap, causes rotor to rotate.
In the existing pneumatic vane motor structure, do not guarantee the control of rotor and end cover clearance.Bearing on the front and rear cover only limits the radially degrees of freedom of rotor, and does not have the restriction of axial freedom.This structure makes pneumatic vane motor (as driving paddle) when driving has the load of axial force, or when output shaft is subjected to axial impact force (as the gear of interference fit is installed at motor drive shaft), will make motor rotor produce axial float, cause the applying of rotor end-face and end cap and can't rotate.Also there is the uncontrollable problem of axial clearance in the motor of this structure when producing assembling, operator's assembling technical ability is had relatively high expectations, and needs in the assembly process to debug repeatedly, influences quality and efficient.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, and a kind of pneumatic vane motor with axial bearing capacity is provided.
The purpose of the present utility model is achieved through the following technical solutions:
A kind of pneumatic vane motor with axial bearing capacity is connected to form by cylinder body, front cover, rear end cover, protecgulum, bonnet, fore bearing, rear bearing and rotor.The inner ring of described fore bearing one end and the rotor of output shaft axle between the rotor end-face are provided with setting sleeve, its outer ring closely is connected with the bottom of front cover cavity, the outer ring of the fore bearing the other end closely connects the interior nose circle face of protecgulum, the cylindrical end face of described protecgulum adopts with the end face of front cover and leaves fixedlying connected of gap, the output shaft of described rotor is being provided with screw thread with fore bearing end face junction, the supporting lock washer of this screw thread and round nut.
The purpose of the present utility model can also be achieved through the following technical solutions:
The length of described setting sleeve is set according to the gap of rotor end-face and end cap end face.The gap size of described protecgulum cylindrical end face and front cover end face can compress the outer ring of fore bearing with circle in the protecgulum and decide.The length of described output shaft screw thread is as the criterion with the inner ring that the assurance round nut can compress fore bearing.Described fore bearing is double-row angular contact ball bearing.The outer ring of circle is provided with annular groove in the described protecgulum, and this groove is provided with O-ring seals, and the cavity bottom of protecgulum is provided with the axle envelope.
Compared with prior art, the utlity model has following beneficial effect:
The axial freedom of output shaft is not controlled on the existing pneumatic vane motor structure, this makes the assembling of motor become difficult on the one hand, in order to guarantee the gap between output shaft and the end cap, needs experienced personnel to debug repeatedly during assembling; This motor can't adapt to the occasion that has axial load to produce on the other hand, such as load prolong downward gravity is axially arranged, interference assembly, accident are beaten motor output shaft etc. on motor output shaft, all can cause pneumatic motor output shaft play and can't work.The utility model is with parts such as setting sleeve, lock washer, round nut, fore bearings, by to the control of setting sleeve length with to the axial limiting of fore bearing and output shaft, effectively controlled the axial position of pneumatic vane motor output shaft, and made the pneumatic motor output shaft that bigger axial bearing capacity be arranged.This structure makes the not only guaranteed quality simply but also better of production assembling of pneumatic vane motor on the one hand; Make this product can adapt to the more applications requirement on the other hand.
