Abstract
A compressor with rotary vane type rolling rotor is composed of casing, casing cover, cylinder in the casing, front and back cylinder covers, follow-up ring in cylinder, drive axle, isolating vanes, air inlet and exhaust joints and drive wheel. Said drive axle parallel to inner surface of follow-up ring has a segment in the cylinder. Said segment has a straight slot on it for installing said isolating vanes. Its advantages are no ripper of rotor, less friction and power consumption, high output power and long service life.
Description
The present invention relates to air compressor, especially relevant with rotary vane type compressor with rolling rotor.
Being seen in the market rotary vane type compressor with rolling rotor is after will being installed in blade in the rotor straight trough throwing away under action of centrifugal force, the direct sliding contact of blade tip and cylinder inner wall and form the height air cavity.Because cylinder body is fixed, just rotor rotation, inboard wall of cylinder block and rotor surface relative velocity are big, the frictional force that adds blade tip and inner surface of cylinder block is increasing, power consumpiton is also increasing, the wearing and tearing aggravation, in the course of time, the metallic dust that the wearing and tearing of blade tip and inner surface of cylinder block are produced is easy to stop up the pipeline that links to each other, to making the whole system can't proper functioning.In addition, also the end surface that easily blade is contacted with cylinder weares and teares into the strain line shape, and directly has influence on tightness.
The objective of the invention is and will disclose a kind of rotary vane type compressor with rolling rotor to the public, it can reduce the friction of cylinder interior spare, thereby improves output power and increase the service life.
The present invention includes frame, cap, cylinder body, front end housing, back cylinder cover, follow-up ring, transmission shaft, isolated blade, advance, exhaust joint and drive wheel, cap is equipped with in the frame front, frame liner suit cylinder body, before having respectively before and after the cylinder body, back cylinder cover, suit follow-up ring in the cylinder body, parallel and the transmission shaft of one external diameter less than the follow-up ring internal diameter is housed near a side inwall of follow-up ring, the same axle center of each joint of transmission shaft, it do not have traditional transmission shaft with eccentric part, at least have the straight trough that is parallel to the center transmission shaft line together on the cylinder intermediate solid drive shaft, one isolated blade is housed in each groove, and isolated blade width and transmission shaft diameter sum must be greater than the inner diameters of follow-up ring.Respectively having the inlet and outlet hole on the forward and backward cylinder cap by the left and right sides of the position of follow-up ring mutually over against transmission shaft, inlet hole on its front end housing links to each other with the air input joint of cap side, and the exhaust port on its back cylinder cover then links to each other with the exhaust joint of frame rear side.In addition, transmission shaft stretches out front end housing and cap forward, and the drive wheel of band engaging and disengaging gear is housed on it stretches out the termination of cap.
The present invention has following advantage: owing to be positioned at the eccentric part that the transmission shaft of cylinder body does not have the conventional compression machine rotor, so it can not produce the unbalanced problem of being brought by the eccentric part rotor of running moment when rotating, thereby avoided the string of rotating shaft in cylinder moving, reduced the friction of cylinder interior spare, and finally can improve output power and the working life that prolongs relevant parts.
The invention will be further described below in conjunction with accompanying drawing and embodiment:
Fig. 1. shape and structure schematic representation of the present invention
Fig. 2. the A-A generalized section of Fig. 1
As depicted in figs. 1 and 2, the present invention includes frame 4, cap 9, cylinder body 1, front end housing 13, back cylinder cover 2, follow-up ring 3, transmission shaft 10, isolated blade 5, air input joint 8, exhaust joint 7 and drive wheel 11.Frame 4 front ends dress cap 9, suit of the interior end of frame the cylinder body 1 that is complementary, the cylinder body front end is equipped with front end housing 13, rear end of the cylinder block is equipped with back cylinder cover 2, in the cylinder body one of suit with its with the follow-up ring of growing 3, parallel and one transmission shaft 10 is housed near a side inwall of follow-up ring, the same axle center of each joint of transmission shaft, it do not have traditional transmission shaft with eccentric part, the diameter of transmission shaft should be less than the inner diameter of follow-up ring, suppose that the transmission shaft diameter is d, the follow-up ring internal diameter is D, so d=(0.74～0.82) * D.At least have the straight trough 14 that is parallel to the center transmission shaft line together on the cylinder intermediate solid drive shaft, present embodiment has the such straight trough in three roads, reach certain width for three straight troughs have the isolated blade in certain degree of depth and the final assurance straight trough, three straight troughs are not over against the axle center fluting but disalignment one angle fluting; One isolated blade 5 all is housed in each straight trough, and isolated blade width and transmission shaft diameter sum must be greater than the inner diameters of follow-up ring, and width of blade L should be (0.56～0.65) * d.Having inlet hole 12 on the front end housing by the left side of the position of follow-up ring or right side mutually over against transmission shaft, having exhaust port 6 on the back cylinder cover by the right side of the position of follow-up ring or left side mutually over against transmission shaft, its front end housing inlet hole links to each other with the air input joint 8 of cap side, and the exhaust port on its back cylinder cover then links to each other with the exhaust joint 7 of frame rear side.In addition, transmission shaft 10 stretches out front end housing 13 and cap 9 forward, and the drive wheel 11 of band engaging and disengaging gear is housed on it stretches out the termination of cap, and its engaging and disengaging gear is an electromagnetic clutch device.
