A worm gear reducer is a reduction transmission device consisting of a worm gear and a worm gear. A worm gear is a helical gear, while a worm gear is a cylindrical body with helical teeth. Worm gear transmission is used for two shafts intersecting at 90 degrees. In worm gear transmission, the active part is the worm gear and the passive part is the...

2024-03-1242030Defects in copper alloy laser welding1. Welding stressThe coefficient of linear expansion and shrinkage of copper are also relatively large. The coefficient of linear expansion of copper is 15% higher than that of iron, and the shrinkage rate is more than twice that of iron. In addition, copper and copper alloys have strong thermal conductivity, wh...
2024-03-1247810The material selection of general mechanical transmission systems is a broad concept. Here, I will mainly talk about the situation of gear transmission in iron-based friction pairs, which is the selection of gear materials.Gears can be made of various materials, including steel, copper, cast iron, aluminum, plastic, and so on. Among them, steel i...
2024-03-1247710Hi there I am new to laser welding We weld aluminum with 2mm thickness The protective lens burnt so fast i change it 3 to 4 time a dayUsing 2000W fiber laser welding machine from depang model number dph-2000So any help to solve the problem
2024-03-1047250When using a servo (Panasonic) to return to the origin in a recent project, if other axes are also moving, the Z-phase zero point signal received by the PLC is easily lost, resulting in abnormal return to the origin position. Later, upon checking the driver manual, it was discovered that the GND of the Z-phase zero point signal needed to be connect...
2024-03-1149620As an indispensable supporting equipment for most lasers, laser chillers are responsible for cooling and cooling the laser. Matching a suitable laser chiller can provide good cooling effect for the laser and ensure its efficient operation. When the laser chiller works for a long time, the cooling effect decreases and the water temperature is not co...
2024-03-11433101. Gear operation generates heata. Overload or ultra high speed.The driving load is too large, causing an increase in gear meshing sliding heat generation.b. Insufficient or incorrect selection of lubricating oil/grease.Too little lubricating oil/grease can cause oil film failure and increase meshing friction. In addition, improper use of lubricant...
2024-03-1143410I recently bought a dual beam co2 laser with a camera. The machine has a ruida RDC6685U controller installed and the software is RDVisionWorks. The way it's supposed to work is the camera takes a picture of the printed fabric, identifies the outline and then cuts. After the cut, it moves on the U-Axis and repeats the action until the job is complet...

2024-03-0944020What speed curve has the highest stability when the servo motor starts or stops. The commonly used trapezoidal velocity curve has significantly poor stability. It is said that according to the 5th degree curve acceleration, the motor torque will not experience sudden changes, and the motor stability is also more reliable?
2024-03-09495101. Transition curve interferenceTransition curve interference refers to the interference at the transition curve between the tooth tip of a gear and the tooth root of the matched gear during the meshing process.2. In order to prevent interference in the transition curve during the meshing process, the selected meshing parameters must ensure...
2024-03-0936410Industrial chillers are undoubtedly familiar to friends in the manufacturing industry. A chiller is a cooling device that provides cooling and cooling for industrial production equipment such as chemical, mechanical, food, microelectronics, and laser processing.During operation, industrial chillers can output ice water that is lower than the ambi...
2024-03-0942310The ultraviolet laser marking machine is a cold processing method, where high-energy molecules in ultraviolet light directly detach the molecules on the metal or non-metal materials that need to be processed, causing the molecules to separate from the material.Electronic mobile phone components, LCD screen engraving QR codes and trademarks, ceram...
2024-03-0844110Steel can be said to be ubiquitous in daily life, but it has a disadvantage that it is prone to rust, especially those without paint or coating protection.Laser is another major invention of humanity since the 20th century, following nuclear energy, computers, and semiconductors. It is widely used in many fields and is known as the fastest knife, ...
