The new gear or new replacement worm pair in the first use, running 7-14 days to be replaced with new lubricants; in the future use, should regularly test the quality of lubricating oil, containing debris or deterioration and into the oil must be replaced. For long-term continuous operation of the gear must be replaced every 2-3 months lubricants tpu double enveloping gear for the daily working time is not more than eight hours of gear must be replaced once every 4-6 months, lubricants; under harsh working conditions double enveloping gear, oil change should be appropriately increased the number of plane enveloping gear during regular oil changes, the reducer should be cleaned, check tooth contact, the worm axial clearance moving gap and bearing tpa double enveloping gear, such as abnormal, should be adjusted or replaced parts; replacement parts, to re-test to post-operational. For reducer continuous work over the course of the operation should always check the oil, when the oil temperature exceeds 90 degrees should immediately stop inspection, troubleshooting, or after changing the oil can only continue to work. A, planar double enveloping worm Vice formation process mainly includes two envelope movement: 1, the first movement is a flat envelope worm gear tooth surface and the surface of the mother worm certain relative motion, enveloping the worm spiral tooth surface; two, the second movement is the first envelope envelope motion a spiral curved surface of the mother worm conjugate movement through a worm gear tooth surface envelope. B, meshing process has the following characteristics: 1, the worm axial arc tooth profile was distributed rd double enveloping gear, while touching teeth: 3-7 teeth; 2, worm tooth surface after grinding hardened precision made tooth surface hardness: HRC "50, roughness Ra" 0.8; 3, machining process and forming process is completely consistent, can guarantee reliable manufacturing precision and meshing theory state; 4, connected at the tooth surface area greater than: 70%; 5 worm gear tooth surface at all times have: continue along the width direction of the teeth of the two occur simultaneously from both ends toward the middle advance: the angle between the line of contact, and the contact line with the direction of the relative velocity close to 90 degrees; 6, tooth Lubrication angle, forming a hydrodynamic oil film and keep good. rd double enveloping gear, double enveloping gear, Runchi gear provided by the Texas Runchi reducer Limited. Texas Runchi reducer Limited (www.sddzjsj.com) strong, credible, in Dezhou reducer, gearbox industry has accumulated a large number of loyal customers.
