Structure using self-locking taper hole press-connection unit to assemble motor and spindle blade in spun yarn electric spindle

Abstract

The invention relates to a structure using a self-locking taper hole press-connection unit to assemble a motor and a spindle blade in a spun yarn electric spindle; the structure comprises a motor anda spindle blade joint member; the motor shaft of the motor is a hollow through hole structure; the shaft rod shape of the output connecting end of the motor shaft is a male cone; a thread segment is arranged on the inner hole of the other end of the motor shaft; the inner hole of an aluminium sleeve of the spindle blade joint member is a female cone; the female cone of the aluminium sleeve and themale cone of the motor shaft are in press-connection through the conical surfaces. The spindle blade joint member structure is designed by using the conical surface self-locking principle, thus greatly improving the spindle mounting / dismounting rate, and ensuring the enterprise production benefits.

Description

Technical field [0001] The invention belongs to a spinning device spindle rod combination, and specifically relates to a structure for assembling a motor and a spindle rod in a spinning electric spindle by using a self-locking taper hole press-fit structure. Background technique [0002] At present, the wire feeding rollers of the ring twister and the two-for-one twisting machine are both mechanically structured or a motor drives multiple rollers through one or two long shafts to complete the wire feeding and twisting; although there are some existing manufacturers A single roller is used to drive the rotation through a single motor, but the connection structure between the motor and the spindle is more complicated, which leads to spinning problems, and it takes time and labor to disassemble and install when repairs are needed, which seriously delays the production schedule and brings significant losses to the enterprise. Summary of the invention [0003] The purpose of the presen...

Problems solved by technology

[0002] At present, the wire feeding rollers of the ring twisting machine and the two-for-one twisting machine are all mechanically structured or one motor drives multiple rollers through one to two long shafts to complete the wire feeding and twisting; although there are some existing manufacturers A single roller is used to drive the rotation through a single motor, but the connection structure between the motor and the spindle is relatively complicated, which leads to problems in spinning. It takes time and effort to disassemble and install when maintenance is required, which seriously delays the production progress and brings great losses to the production of the enterprise.
