Embodiment
In order to understand the utility model further, below in conjunction with the accompanying drawing in the utility model embodiment, the scheme in the utility model embodiment is clearly and completely described.
Shown in Fig. 1, Fig. 2, a kind of bavin that is applied to provided at the utility model moves high-elastic coupling device on screw air compressor, comprises elastomer 1, axle sleeve 2 and high-strength bolt 3.
Shown in Fig. 3, Fig. 4, elastomer 1 is hollow cylinder, the axial direction of elastomer 1 is evenly provided with four axial threaded hole 4, elastomer 1 be evenly provided with four radial screw bore 5 in the radial direction, axial threaded hole 4 and radial screw bore 5 all run through elastomer 1, and stagger mutually in the position of axial screw thread 4 hole and radial screw bore 5.
Shown in Fig. 5, Fig. 6, axle sleeve 2 is hollow cylinder, and axle sleeve 2 inwall axial direction is provided with keyway 6, and axle sleeve 2 outer wall axial direction is evenly provided with four rectangular grooves 7.
Shown in Fig. 1, Fig. 2, elastomer 1 is fixedly mounted on bavin by four high-strength bolts 3 by axial threaded hole 4 and moves on the diesel engine flywheel dish 8 of screw air compressor, bavin moves the screw rod arbor of screw air compressor and key (not shown) and axle sleeve 2 close-fitting, and overlap together with axle sleeve 2 and load in elastomer 1, four high-strength bolts 3 are embedded in the groove 7 on axle sleeve 2 outer wall through the radial screw bore 5 of elastomer 1, make the radial clearance having 6-8mm between the outer wall of the inwall of elastomer 1 and axle sleeve 2.
