Abstract
The utility model provides a rotating body axial fastening structure on a rotating shaft and relates to the field of mechanical parts. The rotating body axial fastening structure comprises a rotating shaft and a rotating body. The end portion of the rotating shaft is connected with a circular disk type nut and a round nut in sequence. First dismounting holes are formed in the circular disk type nut. Second dismounting holes are formed in the round nut. A locating hole is formed in one face, towards the circular disk type nut, of the rotating body. Threaded holes are further formed in the circular disk type nut. Set screws are arranged in the locating hole and the threaded holes. The set screws are connected into the threaded holes of the circular disk type nut in a threaded mode. The end portion of the set screw is inserted into the locating hole of the rotating body. The rotating shaft can stop the circular disk type nut from loosening in the process of reverse rotation of the rotating shaft. The set screws are used for limiting the rotating body and the circular disk type nut. The rotating shaft can stop the circular disk type nut from loosening in the process of reverse rotation of the rotating shaft. Consequently, the axial position accuracy of the rotating body on the shaft is guaranteed, and normal running of a machine is guaranteed. The rotating body axial fastening structure can be widely used for axial fastening between a water pump shaft and an impeller assembly, fastening between the rotating shaft and a coupler, and fastening between the rotating shaft and a belt pulley.
Description
Technical field
The utility model relates to the mechanical fitting field, relates in particular to and is connected in shaft end, is used for the axial locking device of the parts such as impeller locking assembly, coupling, belt pulley.
Background technique
The fastening structure of existing solid of rotation on rotatingshaft; fixing between pump shaft and impeller assembly for example; comprise rotatingshaft, rotary shaft end connects the impeller head, rotary shaft end be threaded successively cake nut and blind hole nut; punching under water when water pump is shut down in pump line; the axle counter-rotating causes nut loosening, and impeller can move axially, and the impeller axially locating is lost; pump can not run well, and still damages to pump.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of more reliable solid of rotation to axially fasten structure at the solid of rotation on axle on rotatingshaft.
the purpose of this utility model is achieved in that solid of rotation axially fastens structure on rotatingshaft, comprise rotatingshaft and solid of rotation, the end of rotatingshaft connects cake nut and round nut successively, the first removal hole is set on the cake nut, the second removal hole is set on round nut, described solid of rotation arranges positioning hole towards the one side of cake nut, tapped hole also is set on the cake nut, in described positioning hole and tapped hole, Cock screw is set, Cock screw is threaded in the tapped hole of cake nut, the end of Cock screw is stretched in the positioning hole of solid of rotation, when reversing, rotatingshaft can stop the cake nut loosening.
The utility model is spacing with heliconid and cake nut by Cock screw, can stop the cake nut loosening when rotatingshaft reverses, and has guaranteed the axial position precision of solid of rotation on axle, thereby has guaranteed the normal operation of machine.Can be widely used in the fastening of fastening, the rotatingshaft of the axially fastening of water pump spindle and impeller assembly place, rotatingshaft and coupling and belt pulley place.
