Specification Brand : YIDOFENG BulletPoint1 : 【Parameter】Model: NMRV040 (small), type: worm gear, speed ratio: 30:1, input hole size: 14 mm 0.55" ,output hole size: 18mm 0.7", speed range: 30:1, input flange model: NEMA34, material of the service housing: aluminium alloy , application: Servo Motor/step motor,Color: slive. BulletPoint2 : 【Features】1.) The worm gear is made of ductile cast iron QT-400, which is well made and easy to carry. 2) The worm gear bar is made of 20CR round steel (carbonated and scared heat treatment, stable transmission and high efficiency), 3.) The reduction housing is made of high-quality ADC12 aluminium die-cast housing, strong sealing, small size, light weight, space-saving installation, not easy to corrode. BulletPoint3 : 【High quality】This worm gear has the properties of waterproof and dustproof, and the structure of the protection class IP55 has a good insulating effect on dust and moisture. It also has the characteristics of large torque, low noise level, stable operation, strong adaptability, large overload and strong impact resistance. BulletPoint4 : 【Wide Applications】 With time delay and increased torque function,It is widely used in light industry, food industry, chemical construction, machinery and equipment, textile industry, building materials, logistics, environmental protection and other fields. BulletPoint5 : 【Notes】1.) Don't hit the shell of the decelerator for gravity hammer to avoid damage. 2.) Pay regularly whether the functions of installation,sealing and transmission shafts are used normally. 3.) The temperature of the lubricating oil should be less than 85 °C. When the oil temperature changes abnormally,and the phenomenon of abnormal noise is generated, it's necessary to stop the inspection immediately. 4.) Replacement of new spare parts must be formally used after running and load test.
