SWL Series Electric Stainless Steel Screw Jack

The screw jack, also known as a helical drive mechanism, is primarily used to convert rotational motion into linear motion or vice versa. There are types that mainly transmit motion, such as the feed screw of machine tool tables, and others that adjust the relative positions of parts, such as helical drive mechanisms. The screw jack consists of a worm gear reducer and a screw, with the减速 part being the worm gear drive, which uses the worm to drive the worm gear for deceleration. The worm gear is equivalent to the nut of the lifting screw, and matches with the lifting screw. 

Features of Screw Jacks:

1The working principle involves ball bearings placed between the screw thread groove of the lead screw and the nut.

2When the screw or nut rotates, the ball bearings roll along the thread groove, resulting in rolling friction between the screw and nut during relative motion. To prevent the ball bearings from rolling out of the groove, return guide devices are installed at both ends of the nut's spiral slots.

3They form a closed loop with the threaded raceway, allowing the ball bearings to circulate within the nut's raceway.

The SWL series screw jack is widely used in various industries such as machinery, metallurgy, construction, chemical industry, culture, and public health. It can accurately control and adjust the lifting or advancing height according to a certain program, and can be directly driven by an electric motor or other power sources, or operated manually. The input speed does not exceed 1500 r/min, with a lifting speed of 2.7 m/min. It comes in different structural types and assembly methods, with lifting heights tailored to customer requirements. The SWL series screw jack, during operation, boasts advantages such as low noise, smooth transmission, and flexible operation; moreover, to ensure safety during use, the jack is equipped with an automatic locking function. In the event of equipment failure, the jack can automatically lock and stop, partially ensuring the safety of the production environment and personnel.

Screw jackA significant portion is due to its internal structure.Screw jack structure. This structure was previously used in reducers to reduce speed while increasing torque, meaning a small amount of force can transmit a large torque. Later, it was found that using it in elevators for lifting or hoisting operations is also an excellent choice, so...screw jackIt was born out of necessity.
