Rotary drive, is an integrated whole circumference rotary driving power source speed reducer, its Slewing Bearing as the transmission mechanism and the follower attachment, driving unit, driving source and shell through a circle on the slewing bearing inner and outer ring in the attachment, and the other is a circle as the driven again, as the connecting base driven working parts, characteristics of such use of slewing bearing itself is the whole week rotary joints, efficient allocation of driving power source and the main driving parts, making it a set of rotary, deceleration and driving functions but also has the advantages of simple structure, convenient manufacture and maintenance of general reducer institutions.

According to transmission form of rotary drive, the drive can be divided for rotary gear and worm rotary drive, gear transmission and inheritance characteristics of worm drive with each other, these two kinds of rotary drive respectively can adapt in high speed and low speed applications, in terms of carrying capacity, better than the performance of the gear worm type. And when using the enveloping worm drive, its bearing capacity, deformation resistance and rigidity have further improved, but the worm gear rotary drive in terms of efficiency is inferior to the rotary drive gear.
According to the opening of the rotary drive mechanism gearing to distinguish, can be divided into open and closed drive rotary, usually open structure for environment is too harsh, and maintenance of application cycle is short, the open parts of the structure is convenient for inspection and maintenance, but also more convenient to replace. On the other hand, the closed structure can provide longer maintenance life cycle in the situation where the environmental conditions are not changed and the environmental pollution level below medium is below.

Modularization
Due to the high integration of rotary drive, users do not need to purchase and process every accessory that constitutes a rotating device, to a certain extent, it also reduces the preparatory process at the beginning of product production, thereby greatly improving labor productivity.
Safety
The worm and worm drive has the characteristic of self - locking in reverse. It can be locked in the opposite direction, that is, the worm drive can only be driven by the worm, but the worm can not drive the worm. This characteristic makes the slewing drive widely used in lifting and aerial operation equipment, while improving the technology content of the host, it also greatly improves the stability of the host and the safety factor of the operation. Compared with the traditional rotary products, the rotary drive is easy to install, easy to maintain, and to save the installation space in a greater degree.
Simplified host design
Compared with the traditional gear transmission, worm gear drive can get a relatively large reduction ratio, in some cases, it can save the reducer parts for the main engine, thereby reducing the purchase cost for the customers, and greatly reducing the failure rate of the main engine.

Code interpretation:
S (E) XX XX (S) 2H (E) B/12R (L) XXX (E) XXX
S (E) - S open type rotary drive, SE fence type rotary drive.
XX - product size, such as: 3 ", 5", 7 ", 9", 12 ", 14", 17 ", 21", 25 "approximate representation of the slewing bearing raceway center distance.
The XX (S) - XX deceleration is not quenched in the gear teeth of the S slewing support, and no - means the quenching of the rotary support teeth.
2H- 2 is a double worm drive, no single worm drive. H indicates that the worm's non input end is six corners and it is not stuffy cap. E- indicates that the worm doesn't have an encoder with the input end. It doesn't mean that the worm's non input end is a stuffing cap.
The input and installation holes of the B- worm are 6B spline. 12 indicates the diameter of the worm input hole is 12mm, 16 indicates the diameter of the worm input hole is 16mm, 25 indicates the diameter of the worm input hole is 25mm, etc. R (L) motor or motor installation direction: the right side or the left side.
XXX (E) - motor, hydraulic motor specifications, E- motor belt built-in encoder, no - Indication motor without built-in encoder.
The final output speed of XXX- rotary drive device, such as 001, 010 and 100, is 100 times the actual output speed. The actual output speed is 0.01rpm, 0.1rpm and 1rpm respectively.
Rotary drive can be used for any need the whole week and rotary speed requirements of the occasion, when the transfer or the body structure need to achieve high precision power transmission, large torque of the sport compact integration of higher requirements for mechanism selection, rotary drive is the best solution.
The more common applications are generally mechanical automatic tracking the whole week rotary structural engineering and construction machinery, solar energy and wind energy and long-term operation, because of its compact structure, short transmission chain, so the rotary drive is relatively easy to achieve high precision and easy digital control, in the field of industrial robots, there are also many applications.
