The worm gear slewing drive is a full-cycle rotary reduction transmission mechanism integrated with a driving power source. The high precision bearings are used as a transmission follower and a mechanism attachment member, and an active member and a driving source are attached to one of the inner and outer rings of the slewing ring. And the casing, and the other ring is regarded as both the transmission follower and the connecting base of the driven working part, so that the slewing bearing itself is a feature of the full-circle rotary connecting member, and the driving power source and the main transmission are efficiently configured. The part makes it a general-purpose reduction transmission mechanism that integrates the functions of rotation, deceleration and drive, while having a simple structure and convenient manufacture and maintenance.

According to the form of the variable speed transmission of the slew drives, it can be divided into a tooth type slewing drive and a worm gear type slewing drive, inheriting the respective characteristics of the gear drive and the worm gear drive, and the two slewing drives can be adapted to medium and high speed and low speed applications respectively. In terms of carrying capacity, the worm-and-worm type performs better than the gear type, and its load carrying capacity, deformation resistance and transmission rigidity are further improved when using an envelope worm drive, but the efficiency of the worm-gear type slewing drive is Inferior to the toothed rotary drive. According to the openness of the slewing drive transmission mechanism, the slewing drive can be divided into open type and closed type. Generally, the open structure is mostly used in applications where the environment is too harsh, the maintenance and maintenance cycle is short, and the open structure is more convenient for the machine. Inspection, maintenance and maintenance are also easier to replace. Closed structures provide a longer maintenance lifecycle where environmental conditions do not change much and are below the level of environmental pollution below medium.

As one of the most professional slew drive manufacturers in China, Maanshan Fuyong Intelligent Technology Co., Ltd. is specialized in the manufacturing and development of slewing ring drive for many years. We sincerely invite and welcome people from all around the world to invest and create more values together.

We have rammer compactor for sale!

Tamping rammer well known as jumping jack in western countries, it makes up of an engine (motor), a small foot (plate). The jumping jack type is mainly used to compact the backfill in narrow trenches for water or gas supply pipes etc and repair pavements and roads in the small area where the plate compactor and roller compactor are not available to enter into. Rammers have the ability to compact a deeper amount of soil than a plate compactor because the force from the plate is more direct.

The torque generated by the engine or electric motor is transferred to reciprocating motion by crank gear, which will pass it on vibrating foot (shoe) through spring cylinder. It has a strong impact force though it is small and light.

Proper Compaction is very important to prevent soil settlement from happening and result in expensive maintenance cost or structural failure. The soil has complex mixtures. It is consisting of minerals, water, air, organic matter while forming on the land’s surfaces. It is always obviously essential step to do soil compaction as part of the building process in advance. Soil compaction is one of the easiest methods of mechanically increasing the density of soil ground.

It is very similar for upright rammer   and plate compactors. In spite of the fact that the structure is different, the working principle and function same. So when should we choose tamping rammer instead of plate compactor? It is easy to recognize on the accordance of the type of soil. The Tamping rammers work obviously great when compacting cohesive soils because of the small size of the plate. The smaller plate size allows for more focused and direct compaction, which comes in handy on soils that require more force to properly compact. More an can be added to each layer which can make the process of filling and compacting a hole or trench, much faster.

Everyone knows that driving power is the core of LED lighting. LED lighting lamps are known as energy-saving, intelligent and long service life. But these basically rely on good driving power. There has been a joke in the industry: If 100 LED lamps broke, 99 ascribe to the driving power supply. As the "heart" of LED lighting, its quality directly affects the quality of LED lighting. LED driver accounts for about 20% of the cost of lamps and lanterns, which not only affects the cost, but also affects the light efficiency and the service life of LED lamp.

Today, I want to introduce a new way of LED driver - DOB. DOB (Driver on Board) or Driverless, which is commonly referred to as "de" power supply, actually doesn't mean driving without power supply, but to remove the traditional AC/DC conversion and integrate the LED driver circuit and the LED lamp string circuit. It is a new driving mode which is different from the traditional switching power supply. It is a new driving mode derived from the characteristics of LED. Efficient driver IC and high voltage LED are the key elements of dob led driver. In terms of intelligent lighting, linear IC driver has its inherent advantages over traditional switching power supply driver. Traditional power supply can also realize intelligent lighting, but the cost or cost of system integration is far more than linear. DOB LED with high-voltage will become a trend. LED package and driver factory is jointly pushing DOB to carry high-voltage LED. It can save inductance, electrolytic capacitor, transformer and other components, further reduce the volume and production cost of printed circuit board (PCB) of lighting system, and eliminate the processing procedure of integrating LED light source and driving circuit by lamp manufacturers. In addition to simplifying lamp development, the introduction of DOB into high-voltage LED light source and drive circuit can also significantly reduce the overall bill of materials (BOM) cost. As we all know, the traditional DC LED system is driven by DC power supply. In order to be used in municipal power supply, AC-DC rectifier must be added. This will cause energy loss in the process of power conversion. And Because of the large size of the driving circuit, the flexibility of lamp design will be limited. By contrast, DOB uses high-voltage LED, which can be directly operated by local voltage only by adding a compact high-voltage driving circuit. Therefore, it has the advantages of small size, high power factor (PF) and high luminescence efficiency.
