Heavy Load Stronger Swivel Drive Wh25-2 for Truck Mounted Crane

WH25 dual worm slewing drive bearing for Truck Mounted Crane
Coresun Drive's geared rotary drive products are suitable for high-speed, medium-load and high-speed light-load conditions, and are especially suitable for supporting use with light-load tooling equipment of construction machinery. Both open and closed types are available. The main parts are made of high-quality medium-carbon alloy steel. Standard heat treatment and fine CNC equipment processing and manufacturing, and optimized design of structure and strength, you can choose the high durability type with hardened tooth surface, or the ordinary type with better economy. This product is economical and easy to maintain. Convenient and low maintenance cost, it is the best choice for installation of civilian products.

Rotation drive slewing drive, it is a kind of integration of driving power source of the week rotary reducer drive mechanism, its slewing bearing as transmission follower and adhesion mechanism, through the rotary bearing inner and outer circle a circle on the initiative of the cover, driving source and shell, and the other a circle both as a follower, and the connection of the base as driven working parts, so using the rotary bearing itself is the week characteristics of rotary joints, efficient allocation of driving power source and the main transmission parts, make it become a kind of rotary, slow down and drive function in a body and at the same time, simple structure, manufacture and maintenance convenient universal reduction drive mechanism.

According to the variable speed drive of rotation drive form, can be divided into type rotary gear rotation drive and the worm and worm wheel drive, inherit the characteristics of gear transmission and worm gear and worm drive each, are the two kinds of rotation drive can be adapted to high speed and low speed applications, in terms of bearing capacity, performance is superior to the tooth worm gear and worm type, and when envelope worm drive is used, its bearing capacity, deformation resistance and transmission have further improve rigidity, but the worm gear and worm type rotary drive in efficiency is inferior to tooth rotation drive.

Heavy-duty dual worm slewing drive Dual-worm slewing drive is usually installed horizontally, and mainly used in engineering machinery. As the worm gear is driven by two worm, it can output larger driving moment, more reliable self-locking performance and better safety performance in restricted space.And it is usually applied in occasions of low speed but larger moment, such as flat-form tire trolley and overhead traveling crane.  
 

Heavy-Duty Dual Worm Slewing Drive

Dual-worm slewing drive is usually installed horizontally, and mainly used in engineering machinery. As the worm gear is driven by two worm, it can output larger driving moment, more reliable self-locking performance and better safety performance in restricted space.And it is usually applied in occasions of low speed but larger moment, such as flat-form tire trolley and overhead traveling crane.  

Advantages

1.For the situations where high torque is required, we introduce and recommend dual worm slewing drives which equip with worm wheel and have high scuffing resistance.

2.Driven by two worm, its output torque and performance is higher than that of single worm slew drive

3.Through excellent heat treatment,hardness of its is high

4.In the common case,our worm reducer is connect to hydraulic motor by universal input hole.

Applications

1.Girder transporter

2.Timber grab machine

3.Gantry crane

4.lifting equipments

5.automotive engine assembly flip and positioning stand
