Abstract
Title: A Structure for Locking Code Disc of Encoder of Motor with Rotating Shaft of Motor Abstract The invention discloses a structure for locking a code disc of an encoder of a motor with a rotating shaft of the motor, which comprises the code disc and the rotating shaft arranged in a center through hole of the code disc by penetration, wherein a plurality of claws extending axially are further circumferentially arranged at the center through hole on the code disc, the plurality of the claws are clamped through a clamping device, and the clamping device is a coil spring sheathed on the outer ring surfaces of the claws. When the code disc is clamped, only the code disc needs to be sheathed into the rotating shaft, and then the coil spring is sheathed on the outer ring surfaces of the claws. As the coil spring has certain elasticity, the structure has the interference effect during clamping, the locking is stable, the structure is simple and the assembly is convenient. ---- --- ---- - ------ ------- ------ .. -- -1---. ...
Description
Description A Structure for Locking Code Disc of Encoder of Motor with Rotating Shaft of Motor Technical Field The invention relates to a structure for locking a code disc of an encoder of a motor with a rotating shaft of the motor. Background of the Invention An interference fit structure is regularly adopted between an existing code disc of an encoder of a motor and a rotating shaft of the motor, or a clamping groove 01 is arranged on the motor as shown in Figure 1, and a clamping structure of a clamping block 02 is arranged on the code disc. When the interference fit structure is adopted, the assembly is inconvenient and the interference fit structure is easy to become loose after a long period of time; however, when the clamping groove-clamping block structure is adopted, the clamping groove-clamping block structure is easy to become loose due to errors, thereby having certain insufficiencies. Summary of the Invention The technical problem to be solved by the invention is to provide a structure for locking a code disc of an encoder of a motor with a rotating shaft of the motor, which is stable in locking, good in effects, less prone to causing looseness between the code disc and the rotating shaft, simple in structure and convenient to assemble. In order to solve the technical problem, the invention adopts the following technical scheme: the structure for locking the code disc of the encoder of the motor with the rotating shaft of the motor comprises the code disc and the rotating shaft arranged in a center through hole of the code disc by penetration, and the structure is characterized in that a plurality of claws extending axially are further circumferentially arranged at the center through hole on the code disc, and the plurality of the claws are clamped through a clamping device. Preferably, the clamping device is a coil spring sheathed on the outer ring surfaces of the claws. Preferably, the claws are three claws which are uniformly circumferentially arranged. The plurality of the claws extending axially are circumferentially arranged at the center through hole on the code disc, and the plurality of the claws are clamped through the coil spring which is sheathed on the outer ring surfaces of the claws. When the code disc is clamped, only the code disc needs to be sheathed into the rotating shaft, and then the coil spring is sheathed on the outer ring surfaces of the claws. As the coil spring has certain elasticity, the structure has the interference effect during clamping, the locking is stable, the structure is simple and the assembly is convenient. Brief Description of the Drawings In combination of the following figures, the invention is further described. 1 Figure 1 is a schematic diagram of matching structure of structure for locking code disc of encoder of motor with rotating shaft of motor; Figure 2 is a top view of Figure 1. Detailed Description of the Invention As shown in Figure 1 and Figure 2, a structure for locking a code disc of an encoder of a motor with a rotating shaft of the motor of the invention comprises the code disc 1 and the rotating shaft 2 arranged in a center through hole of the code disc by penetration, wherein a plurality of claws 3 extending axially are further circumferentially arranged at the center through hole on the code disc, the plurality of the claws are clamped through a clamping device, the clamping device is a coil spring 4 sheathed on the outer ring surfaces of the claws and the claws in the embodiment are three claws which are uniformly circumferentially arranged. 2
