The only official main station of Woson reducer

product Overview:

JWM series worm gear screw lifts belong to the machinery, metallurgy, construction, water conservancy equipment and other industries with a wide range of reducer accessories. They have many functions such as lifting, lowering and replacing auxiliary parts, tilting and adjusting various height positions.

Overview of JW screw lift

One JWM type (trapezoidal screw type)

Low speed, low frequency

JWM type (trapezoidal screw type) is suitable for low-speed and low-frequency occasions. The main components are: precision trapezoidal screw pair and main precision worm gear pair.

1 Economy:

Compact structure, simple operation and convenient maintenance.

2 Low speed, low frequency:

It is mainly used in places with heavy load, low speed and no excessive work.

3 Maintain the load: The trapezoidal screw has an automatic locking function, which can maintain the load even without a braking device.

The self-locking function will occasionally fail when it is subjected to vibration or impact in the radial direction. At this time, a braking device must be added.

Two JWB type (ordinary ball screw type)

High speed, high frequency

JWB type (ordinary ball screw type) is suitable for high-speed, high-frequency and high-performance devices. The main components are precision ball screw pair and high-precision worm gear pair.

1 High efficiency: Rolling friction improves the efficiency of the whole machine, and only a small driving source is needed to generate a great driving force.

2High-speed: Compared with the trapezoidal screw, the speed is greatly improved, and it can run easily and at high speed.

3 Lengthen the length: The use of improved ball screw can increase the working life by more than 3 times.

Note: ① It has no self-locking function, it needs to add a brake device or a drive source with brake.

②JWH large pitch ball screw type is available for consultation.

Three machine assembly shapes and features

Basic form (US, DS)

　　　The nut rotates the screw rod to move up and down, this is an ordinary elevator accessory

United States: put on DS: hang off

Please choose a suitable elevator according to the radial direction and the installation direction (press up or hang down)

When the screw shaft is raised and lowered, it will generate a rotating force, so measures must be taken to prevent it from rotating.

Rotation stop structure (UM, DM)

UM: Put it on DM: Hang it down

It is suitable for the situation when the top is running without connection or the rope is pulled by the pulley and cannot be prevented from rotating.

Please the appropriate elevator (UM or DM) according to the load direction and installation direction

　　Under normal circumstances, the elevator must have the stroke caused by the lifting of the screw shaft and the space required by the screw cover. If you want to increase the stroke in a limited space, the use of this movable nut structure is very suitable (screw shaft rotation, The movable nut moves). The top end of the screw shaft is cylindrical, so when the stroke is long, the shaft end can be supported to obtain good results.

　　UR: squeeze up DR: hang down

　　 Please the appropriate lift according to the load direction and installation direction (press up or hang down)

　　 Note: In the ion and model representation method, the placement direction of the nut should also be indicated.
