Slew drive solution provider-Unique Transmission

The wear and tear of the gear teeth can cause rotation clearances in the worm screw. It is therefore necessary to check that rotation after 700 hours of operation or every 6 months, so as not to exceed approximately 20° of free rotation.  In order to measure that rotational clearance, the motor must be disconnected and the screw turned manually, measuring the angle rotated by the screw with respect to a previously specified starting position.  The previously specified inspection interval must be reduced to 200 hours of operation if the clearance reaches approximately a 15° rotation. Should the clearance continue to increase, the inspection should be reduced to 50-100 hours of operation, and in the event that it exceeds the maximum permissible value the system must be replaced. Checking mounting bolts To compensate for possible settling, it is necessary to retighten the bolts to the prescribed torque. This shall be done after no more than 100 hours of operation and without exte...

 Cleaning the slewing drive and the mounting structure: • Remove extraneous material from supporting surfaces (including paint residues, welding beads, burr formation). Clear corrosion protection coating from supporting surfaces of the slewing drive. Cleaning material does not penetrate into the slewing drive. Cleaning material that attacks the sealing material is not used. Applicable cleaning materials: Cold solvents (e.g. white spirit, diesel oil, Kaltryl KEV). Lubricating the slewing drive: • slewing drive are supplied fully lubricated. They shall be greased again prior to initial operation. It is essential to use the greases specified on the delivery drawing. Choice of mounting bolts: Prescribed sizes, number and quality grades shall be used. • Grip ratio (grip length to diameter of bolt) shall be observed from minimum ≥5 to maximum ≤10. • Bolts with a fully threaded shaft are not permissible. • The function and lifespan as well as the durability of the bolt connection are aff...

This system ( slewing bearing driven by a worm screw) is a complete assembly and is ready for installation. And furthermore can be very easily integrated into existing applications.  It consists of a ball bearing or rollers capable of simultaneously withstanding axial, radial and moment loads, a hydraulic or electric motor to generate relative movement between the two rings, and a fully enclosed coating protecting the ring from contamination, damage and loss of lubricant.  Moreover, with these assemblies the installation of components is avoided and is available in a comprehensive range of several standard sizes. In the following Figure all the components which make up the entire assembly can be discerned. From among its main advantages the following can be highlighted: • It is very compact, making it suitable for installations requiring space saving. • Having a very high load capacity in a very compact design. • Having a long service life. • Having low maintenance costs. • A...

Everyone knows that slewing bearing and slewing drive need to be filled with grease regularly, it cannot be used without lubrication, otherwise it will cause damage to the slewing bearing and slewing drive. The slewing bearings and slewing drives and other products from Unique Transmission have been filled grease before leaving from factory.  We choose to use Mobilux EP2 grease, people who buy grease often know that there are many types of grease brands on the market, and quality is uneven, fake greases are emerging in endlessly. Therefore, we must buy major brands of grease through formal channels. If add fake grease, it will also cause damage to the slewing bearings and slewing drives, our Mobilux EP2 grease is purchased through Mobil official website authorized dealers to ensure the grease quality.  Why did we choose Mobilux EP2 grease as the grease for slewing bearings and slewing drives? Let's get to know the Mobilux EP series grease. Mobilux EP series are marked as 0, 1...

Worm gear slew drive and spur gear slew drive are both highly integrated modular slewing reducers. Users do not need to purchase individual parts one by one and then assemble them into products with worm gear slew drive and spur gear slew drive functions. Reduce unnecessary production preparation procedures, greatly improve production efficiency. In a sense, the spur gear slew drive can replace all geared slewing bearings. Compared with slewing bearings, it has the advantages of simple installation, easy maintenance and greater saving installation space. What are the similarities and differences in the design and use of the worm gear slew drive and the spur gear slew drive? Unique transmission will answer for you.  Similarities Worm gear worm shaft slew drive and spur gear slew drive both use slewing rings as the main moving parts. The slewing bearings play the role of driving the equipment to rotate and bearing the equipment load. The worm or gear is used as the driving part of t...

 The global slewing drives market attained a value of USD 2 billion in 2020. The slew drives market is further expected to grow in the forecast period of 2021-2026 at a CAGR of 4.5% to reach USD 2.7 billion by 2026. The slewing drives market is expected to be driven by the rising construction sector and a growing adoption of solar-powered energy alternatives. The Asia Pacific is a key market in the industry due to the rising construction industry and growing industrialisation within the region. The single axis slewing drives dominated the regional market in 2020. The slewing drive refers to a gearbox that transmits a torque required for rotation while keeping the axial and radial loads held safely. Based on its axis types, the slewing drives market can be segmented into: Single Axis Dual Axis Multiple Axis By gear, the industry can be bifurcated into: Worm Gear slew drive Spur Gear slew drive The slewing drives market can be broadly categorised on the basis of its applications seg...

Due to the slew drive is usually used as a general component of large scale equipment, therefore the slewing drive product is in a component assembly state when it is delivered to the user, it needs to be connected and assembled with the host when it is delivered to the complete machine manufacturer.In this process, especially for the closed structure slew drive, because the connection between the housing and the internal transmission part and the connection between the entire slewing drive and the host use the same set of connecting holes, so when the slewing drive leaves the factory, there is already a pre-connection between the housing and the internal transmission parts.   This connection involves the transmission clearance and position adjustment of the internal transmission parts of the slewing drive. Therefore, when connecting with the host, need to keep these pre-connections in the same set of flange holes. The other holes reserved by the manufacturer of the slew drive for...
