Abstract

The invention discloses a linear motor, which comprises a front cover assembly, a rotor assembly, a stator assembly, a screw and a gear mechanism, wherein the gear mechanism comprises a nut bevel gear, a first cone gear, a second cone gear and a third cone gear; the nut bevel gear is fixedly connected to the rotor assembly; axes of a cone gear part of the nut bevel gear and the screw are coincided; a nut part of the nut bevel gear is in thread fit with the screw; the first cone gear is connected to the screw in a sliding mode along the axial direction, and the first cone gear and the screw are arranged in a coaxial mode; the second cone gear and the third cone gear can be respectively meshed with the nut bevel gear and the first cone gear and can rotate synchronously; and a transmission ratio of the nut bevel gear to the second cone gear is unequal to that of the third cone gear to the first cone gear. By adoption of the linear motor provided by the invention, output force of the motor is increased by using the structural advantages of gear transmission.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a linear motor. Background technique [0002] With the continuous development of science and technology, energy saving has become the most concerned aspect of every design worker, that is, how to use the least resources to obtain the greatest benefit has become an important task for design workers. Motors are widely used in our daily life, and how to design efficient motors is the lifelong pursuit of every motor designer. If the output of the motor is increased simply by improving the characteristics of the motor, it will inevitably bring a lot of difficulties to the design of the motor, and the increased output torque is always limited. This device generally includes three parts: the motor stator, the motor rotor and the transmission device. [0003] Existing installations such as figure 1 As shown, the device includes a screw output shaft 1, a front cover 2, a rotor 3, a stato...
