With the increasing of LED efficiency and cost reduction, LED lighting increasingly become the incandescent light bulb and fluorescent lamp of the perfect substitute. However, due to the LED illumination system is very complex; Across the optics, electricity and heat, etc, therefore, in large scale application, will often appear power life not matching and reliability than problems, which LED advantage can't play. In short, the LED lighting (especially LED street lamp) large scale application is the real driving power supply bottlenecks. Power Integrations company (hereinafter referred to as PI) LED product marketing manager Andrew Smith said: "as the early compact fluorescent lamps (CFL) technology for initial quality is low and encounter as demand fell, LED the reliability of the street lamp lighting was questionable. A lot of premature failure force the place when the bureau and other customer to reconsider the LED technology. To solve quality problem, LED the main advantag...

 Understanding The Functions of a Harmonic Balancer And an Underdrive Pulley A harmonic balancer is an engine component attached into the crankshaft of the engine. Its purpose is to help in preventing or dampening vibration that may result into damage on other parts of the engine. Typically, it is mounted at the front of the engine and it is routed around with the serpentine belt along with the other pulleys in the system. The pulley is constructed of robust, durable metal resistant to high temperatures common in the compartment of the engine. In some cases, it is shaped to help in keeping the belt in place. What is the Main function of a Harmonic Balancer? The main function of a harmonic balancer is to prevent any damage to the crankshaft of the engine. The moment the engine cylinders fire during combustion, they enable the torque to be imparted onto the crankshaft. Then the crankshaft tries to resist the torque that leads to vibration. This process is not actually damaging the cr...

As a precision reducer, which is the core component of industrial robots, compared with general-purpose reducers, robot reducers are required to have the characteristics of short transmission chain, small size, high power, light weight and easy control. It is understood that there are two main types of reducers currently used in articulated robots: RV reducers and harmonic reducers Principle of RV reducer and harmonic reducer RV reducer: It is used for the three joints of the waist and elbow of the leg of the robot with large torque, and the industrial robot with large load uses RV for one, two and three axes. Compared with the harmonic reducer, the key to the RV reducer lies in the processing technology and assembly process. RV reducer has higher fatigue strength, stiffness and life. Unlike harmonic drive, as the use time increases, the movement accuracy will be significantly reduced. Its disadvantage is that it is heavy in weight and large in size. Harmonic reducer: For industrial ro...

Regardless of the lubrication effect of the planetary   reducer, friction will still occur when the planetary reducer is started. This friction will cause changes  in the size, shape and surface quality of the relevant parts, which will lead to wear and increase the fit  clearance between the relevant parts. Therefore, when the gap exceeds a reasonable range, the accuracy  needs to be adjusted. How to adjust the accuracy of planetary reducer? The editor of Tuoda official website  will introduce to you. 1. Adjust the guide precision of the guide rail In general mechanical equipment,  whether the gap between the guide rails is appropriate, usually a 0.03 mm or 0.04 mm thick feeler gauge is  inserted into the end face, and the insertion depth cannot exceed 20 mm. If the guide rail gap is improper,  it should be adjusted in time. 2. Adjustment of the gap between the screw and nut of the worm gear screw  elevator Screw elevator nut drive is a...

A gear motor is a unit that comprises an electric motor and a reduction gear. Typically, these would be available in planetary, planetary-lantern and wave transmissions. As there is a growing demand for compact units these days, many manufacturers now prefer to mount the driving gear of the reduction gear directly on top of the motor shaft. A DC gear motor finds wide-ranging applications across different industries. They are often a part of several industrial and consumer products. These devices need to be manufactured by specialized enterprises to ensure that they are truly efficient and reliable. Depending on where you need to use these motor gears, you can use an appropriate lubrication system to operate the motor gears in tilted, horizontal or vertical positions. So, essentially, a DC gear motor is also described as "normal DC motors that have been geared down to decrease their speed and increase their torque." The best part is that these gears are also very easy to rever...
