Sede worm gear ball screw elevator JWB20 internal leveling machine dedicated screw elevator

The JWM worm gear screw elevator has many functions such as lifting, lowering, pushing with auxiliary components, flipping, and adjusting various height positions

JWM worm gear screw lift is a basic lifting component with many advantages such as compact structure, small volume, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, and long service life It can be used individually or in combination, and can accurately control and adjust the height of lifting or propulsion according to a certain program. It can be directly driven by an electric motor or other power, or manually operated It has different structural and assembly forms, and the lifting height can be customized according to user requirements

Type (trapezoidal screw type)

Low speed, low frequency

JWM type (trapezoidal screw type) is suitable for low-speed and low-frequency applications, mainly composed of

The components are: precision trapezoidal screw pair and high-precision worm gear pair

Economy: Compact structure, easy operation, and convenient maintenance

Low speed and low frequency: mainly used in places with high loads, low speeds, and no need for frequent work

Maintain load: The trapezoidal screw has an automatic locking function, which can maintain load even without a braking device When subjected to large vibrations and impact loads, the self-locking function may occasionally fail, and in such cases, an external braking device must be applied

Type (ordinary ball screw type)

High speed and high frequency

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

High efficiency: By using rolling friction, the overall efficiency of the machine is improved, and only a small driving source is needed to generate a large output

Driving force

High speed: Compared with trapezoidal screws, the speed has been greatly improved, making it easy and high-speed to operate

Long service life: High quality ball screw is used to increase its working life by more than 3 times Note: It does not have self-locking function,

An additional braking device is required or a drive source with braking is selected

Technical parameters: Anti rotation structure (UM, DM)

UM: Attach DM: Hang down

Suitable for operation without a connection at the top or for ropes that cannot be prevented from rotating due to pulley pulling

situation Please choose the appropriate elevator (UM or DM) based on the load direction and installation direction

Active Nut Construction (UR, DR)

-In general, the elevator must have the required travel and screw cover due to the lifting of the screw shaft

When you want to increase your travel within a limited space, using this movable nut construction is very suitable

(The screw shaft rotates and the movable nut moves) The top of the screw shaft is cylindrical, so during long travel,

By using a support method at the shaft end, a good transmission effect can be achieved

UR: Attach DR: Hang down

Please choose the appropriate elevator (to be lifted or secured) based on the direction of the load and installation direction. Note: Selection and model

In the representation method, it is also necessary to indicate the placement direction of the nut
