Problems solved by technology

Couplings for encoders usually use slit couplings, elastic diaphragm couplings, "8"-shaped couplings, etc. The defect of these couplings is that they cannot work normally or have a long life under harsh industrial conditions. too short

Abstract

The invention relates to a coupling special for an encoder. The coupling special for the encoder comprises a pair of axle sleeves, and clamping claws are fixed to each axle sleeve. The inner diametersof the two axle sleeves are correspondingly matched with a motor shaft and an encoder shaft and are fixedly connected to then shaft ends by fastening screws. The bowl-shaped elastic clamping claws are fixedly connected with the peripheral of each axle sleeve. N claw clacks which are distributed uniformly at intervals, and a claw handle of each claw clack replicates to one side to form a bowl-shaped structure. Under the action of axial force, the claw clacks of the two clamping claws are embedded into the gap of the opposite claw clacks in an interlaced mode, and the two clamping claws are connected to realize the transfer of force between the shaft motor and the encoder shaft. According to the coupling, the elastic connection between the encoder and the motor shaft is guaranteed, and whenthe motor shaft appears axial endplay and impact, the coupling buffers and absorbs energy to ensure the safety of the encoder; when the motor shaft appears circumferential impact, the coupling overcomes the rotary inertia of the encoder, and the feedback accuracy of the coupling is guaranteed; and when the clamping claws are in abrasion, it is guaranteed that the two clamping claws are always incontact with each other by pre-tightening force, and the safe, stable and reliable operation of the encoder is effectively guaranteed.

Description

technical field [0001] The invention relates to the connection and installation of an encoder and a servo motor shaft, in particular to a special shaft coupling for an encoder that can protect the encoder and ensure feedback accuracy. Background technique [0002] At present, in order to ensure the accuracy and facilitate installation of the encoder equipped with the servo motor, the rotor and stator are installed as a whole through bearings. The encoder rotor is fitted with the motor shaft, and the stator is fixed on the motor. In order to ensure the life and accuracy of the encoder, a coupling will be installed when the rotor is connected to the motor shaft. When the motor shaft is impacted and moved, the coupling can partially block the impact energy and avoid damage to the encoder. In order to ensure the feedback accuracy, the coupling can overcome the inertia of the encoder rotor rotation without deformation. Couplings for encoders usually use slit couplings, elastic ...
