High-precision Worm Gear Meshing Pair
The worm gear is centrifugally cast from high-strength tin bronze, while the worm is quenched and precision ground. Uniform tooth clearance ensures smooth transmission without jamming, ideal for high-precision lifting and fine adjustment.
Split Multi-port Mounting Structure
Multiple lateral and axial mounting holes are reserved on the housing. Replaceable screw ends including flange top plate, ball joint and U-clevis allow vertical, horizontal and inclined installation at any angle.
Dual Dustproof & Sealing System
Oil-resistant skeleton oil seals are embedded on the housing end faces, and telescopic bellows protect the screw rod. Dust, moisture and cutting fluid are blocked from entering transmission parts, suitable for outdoor and humid workshop harsh conditions.
Balanced Load Bearing & Anti-deformation
Integrally cast ductile iron housing with uniform wall thickness resists cracking and deformation under long-term full load, delivering outstanding stability for heavy-duty continuous operation.
Flexible Drive Compatibility & Strong Expandability
The main housing requires no modification to match handwheels, servo motors, reduction motors and bevel gearboxes. Single independent lifting or multi-unit synchronous linkage systems can be assembled quickly.
Low Operation Loss & Cost-saving
Long-term oil bath lubrication lowers dry abrasion of gears. The self-locking design eliminates extra brake accessories, cutting procurement and maintenance costs for long-term economical operation.
Q: Will HK trapezoidal worm screw jack slide down after power failure?
A: Standard trapezoidal screw models have self-locking function to hold loads steadily. For high-speed heavy-load working conditions, brake motor is recommended for double safety. Ball screw versions have no self-locking function, brakes are mandatory.
Q:What driving methods are compatible with HK jacks?
A: It supports hand crank, standard motor, brake motor and gearbox linkage drive. Two main types are provided: HK shaft input type and HKD direct motor flange type, with single or double input shafts optional.
Q:Can the lifting stroke be customized? What is the maximum limit?
A:Custom stroke is available. The maximum length of single-stage screw is 3 meters. Telescopic dust covers can be equipped for stroke over 3 meters, and double-stage telescopic screw jacks are suggested for ultra-long heavy-load applications.
