Detailed Description
As shown in fig. 1 and 2, a coupler for laboratory equipment comprises a driving pulley 1 and a driven pulley 2 which are symmetrically arranged, a synchronous belt gear ring 5 and a retainer ring 3; the driving pulley 1 and the driven pulley 2 respectively comprise a wheel part and a sleeve part, the sleeve parts are coaxially fixed on the end surface of the outer side of the wheel part, the outer ring of the wheel part is of a gear structure, the left end of the inner ring of the synchronous belt gear ring 5 is meshed with the driving pulley 1, and the right end of the inner ring of the synchronous belt gear ring 5 is meshed with the driven pulley 2; the sleeve part of the driving pulley 1 and the sleeve part of the driven pulley 2 are respectively sleeved with a check ring 3, the check rings 3 are detachably connected with the pulley parts, and the two check rings 3 limit the synchronous belt gear ring 5.
The retainer ring 3 is mounted on the wheel part through a plurality of bolts 4 uniformly distributed along the circumferential direction of the retainer ring.
The inner ring surface of the sleeve part is provided with a key groove, and the sleeve part is provided with a jackscrew hole communicated with the inside. In use, the jackscrew can be used to jack the rotating shaft inserted in the sleeve portion.
The tooth form of the synchronous belt gear ring 5 is an HTD tooth form. The HTD tooth profile has large angular deviation and radial deviation, and the axial error correction is more excellent. Need not to install explosion-proof shell, safe effective, molding and vibrations are little.
The synchronous belt gear ring 5 is made of PU material or chloroprene rubber material.
The utility model discloses during the use, install driving pulley 1 in the drive shaft, install driven pulley 2 on the driven shaft, utilize hold-in range ring gear 5 to connect driving pulley 1 and driven pulley 2 transmission, utilize the skew of hold-in range ring gear 5 when two retaining rings 3 prevent high-speed rotation. When the synchronous belt is disassembled, one retainer ring 3 is disassembled, and the synchronous belt gear ring 5 is pulled down from the belt wheel.
The above, only be the utility model discloses a preferred embodiment, it is not right the utility model discloses do any restriction, all according to the utility model discloses the technical entity all still belongs to any simple modification, change and the equivalent structure change of doing above embodiment the utility model discloses technical scheme's within the scope of protection.
