Bolt propeller

Abstract

The invention discloses a bolt propeller which comprises a motor shell. A frameless torque motor is arranged in the motor shell, a nut and a nut adapter are arranged in the frameless torque motor, the nut is in transmission connection with the frameless torque motor through the nut adapter, and a lead screw matched with the nut is arranged in the nut. The bolt propeller further comprises a guide pushing column arranged a the extending end of the lead screw. According to the structural design, a driving rod in a traditional motor is omitted, the lead screw is directly installed in the motor, utilization of the length space in the motor is achieved, and therefore the size of the device is greatly reduced.

Description

technical field [0001] The invention relates to the field of thrusters, in particular to a bolt thruster. Background technique [0002] The pin thruster is a driving part that can adjust the telescopic state at any time, and can be used in vehicle transportation, pushing goods, fixed support and other operating environments; however, the drive motors used in the current pin thrusters all have the disadvantages of large and complex structures; [0003] For example, Chinese patent CN201621093672.2 discloses the motor structure commonly used in the market. The structure includes a fixed connection of the front end cover and the rear end cover. The stator is fixed inside the motor. The hollow rotor assembly is installed in the stator. The magnetic steel group bonded by the iron core and the magnetic steel and the hollow shaft in the magnetic steel group, the bearings sleeved at both ends of the hollow shaft are erected on the front end cover and the rear end cover respectively; ...

[0002] The pin thruster is a driving part that can adjust the telescopic state at any time, and can be used in operating environments such as vehicle transportation, pushing goods, and fixed support; however, the drive motors used in the current pin thrusters all have the disadvantages of large and complex structures;

[0003] For example, the Chinese patent CN201621093672.2 discloses the commonly used motor structure on the market. The structure includes a fixed connection of the front end cover and the rear end cover. The magnetic steel group bonded by the iron core and the magnetic steel and the hollow shaft in the magnetic steel group, the bearings sleeved at both ends of the hollow shaft are erected on the front end cover and the rear end cover respectively; the screw rod of the ball screw pair passes through the front end The cover extends into the hollow shaft of the hollow rotor assembly, and the screw is fixedly connected to the hollow shaft. When the drive rotates, the ball screw only rotates to drive the nut on it to move back and forth, so the ball screw is located in the space inside the motor. Cause waste, so that miniaturization requirements cannot be achieved
