Description
Technical Field
The utility model relates to a bent axle that is used for the air compressor machine to carry out air compression.
Background
In various production activities, the air compressor is widely applied as an air power source, in the process of air compression of the air compressor, the air compression crankshaft is used as a core part, whether the air compression crankshaft is reasonable in design or not is related to the compression efficiency, the service life and the running stability of the air compressor, but after the existing air compression crankshaft is used for a long time, the loosening phenomenon often occurs, friction is easily caused between the air compression crankshaft and a compression inner cavity of the air compressor, redundant vibration is generated, the compression efficiency and the service life are not good, and larger noise is generated, so that a new air compression crankshaft is needed to be designed to meet the actual use requirement.
SUMMERY OF THE UTILITY MODEL
The utility model provides a bent axle for air compressor machine in view of this, can effectively overcome current air compressor bent axle defect, have better use and popularization effect.
The utility model provides a bent axle has the reel for the air compressor, the reel is the circular that the up end was cut flat in the elevation view direction, the rear side of reel is provided with the cylindrical step of backward extension, the centre of a circle of cylindrical step is located the reel centre of a circle and is cut between the up end of flat, the central point department of reel is provided with the shaft hole that link up, be provided with the keyway on the shaft hole, be used for inserting the transmission shaft of taking fixed bulge, center department at the up end is provided with the tight screw of support that stretches into to the shaft hole, be provided with in supporting tight screw and support tight screw, be used for preventing that the transmission shaft from rocking for the reel.
The lower half part of the shaft disc is also provided with a fastening groove which is communicated with a shaft hole on the shaft disc, a compression channel is arranged in the shaft disc, the compression channel penetrates through the fastening groove and penetrates through the shaft disc, the fastening groove is used as a boundary, one end of the compression channel is a compression channel I with a threaded hole, and the other end of the compression channel II is a compression channel II with a mirror surface; and a screw step is arranged at the outer end of the pressing channel II, and a locking screw is spirally arranged in the pressing channel.
The locking screw is a flat head screw.
The concave holes for matching are respectively arranged on the two sides of the abutting screw holes on the shaft disc, so that the actual gravity center line of the shaft disc is ensured to be coincident with the center line of the shaft disc, no eccentric force is generated when the shaft disc rotates, and the rotation stability is ensured.
The utility model discloses an assembly method does: the transmission shaft is inserted into the shaft hole with the key groove, the surface of the transmission shaft is tightly abutted by the abutting screw to prevent sliding, the flat head screw is inserted into the first pressing channel along the second pressing channel and screwed, after the flat head screw is screwed, the head of the flat head screw is completely screwed into the shaft disc, the rotation of the shaft disc is not influenced, and the fastening of the transmission shaft and the shaft disc can be further ensured through the flat head screw without sliding.
The utility model discloses simple structure, convenient to use, on supporting tight screw and supporting the basis of tight transmission shaft, further produce the extrusion to fastening groove through the crew cut screw, produce even centripetal extrusion force, and then the reel tightly embraces the transmission shaft, guarantees the steady when the reel rotates.
