Description

Technical Field

[0001] The present invention relates to the field of linear motors, and more particularly to a high-speed linear motor. Background Art

[0002] A linear motor is a motor that realizes linear motion. It breaks through the traditional mode of obtaining linear motion through intermediate conversion mechanisms such as lead screws, racks, and belts in a rotary motor. A linear motor can directly generate linear motion, making the equipment structure simpler and the operation more efficient.

[0003] In the related art, a high-speed linear motor generally includes a base, a stator, a slide base, and a mover; the stator is fixedly connected inside the base, the slide base is arranged on the base, the mover is fixedly connected to the bottom of the base, the mover is adapted to the stator, and two opposite sides of the base are fixedly connected with T-shaped slide rails. The two T-shaped slide rails are parallel to each other. Connecting seats are integrally formed on both sides of the slide base. Two groups of limiting components are rotatably installed on the connecting seats. The two groups of limiting components are respectively located on the upper and lower sides of the T-shaped slide rails. Each group of limiting components includes a plurality of rollers arranged at equal intervals. Grooves adapted to the T-shaped slide rails are formed on the plurality of rollers. Lubricating oil is applied to the T-shaped slide rails; during the operation of the linear motor, the lubricating oil will deteriorate in performance due to the mixing of impurities such as dust and metal particles. It is necessary for the staff to regularly clean the old lubricating oil on the surface of the T-shaped slide rails and reapply new lubricating oil to reduce the friction between the T-shaped slide rails and the rollers and extend the service life of the T-shaped slide rails.
