Greenhouse shading materials rack and pinion

Harbin / Changchun / Shenyang / Shijiazhuang various greenhouse materials wholesale / pinion special shade - Henan Goshen greenhouse pinion Harbin / Changchun / Shenyang / Shijiazhuang various greenhouse materials wholesale / pinion special shade - Henan Goshen greenhouse gear rack inside and outside the greenhouse shading / insulation pull curtain system within driving force transmission member, a direct impact on the rack and pinion drive system and the use of safe life. Gear can be divided according to their shape cylindrical gears, bevel gears, non-circular gears, rack, worm; shape into a straight line by tooth gears, helical gears, miter gears, gear curve; according to the tooth surface where the points an external gear, the internal gear; can be divided according to the manufacturing method of casting a gear, gear cutting, rolling gear, sintered gears. Rack and pinion means toothed bars for the gear, bevel gear or worm gear meshing. A tablet or a straight bar, when it has a series of equally spaced teeth, called the rack. Rack and pinion gears are straight strip bite of gear, the gear can be said that the pitch becomes a special case of the size of infinity. Rack and pinion gear can be divided into straight and helical rack rack, respectively, with the spur gear and paired helical gears; rack tooth profile is a straight line rather than involute (compared to the tooth surface in terms of plane ), equivalent to the pitch circle radius is infinite cylindrical gear. Rack and pinion drive system works by rack and pinion drive system is mainly geared motor, shaft, drive card, rack and pinion, push rod, support rollers and other components. This system is running smoothly, durable, large shade inside and outside the United Greenhouse preferred drive form. Driven by geared motor drive shaft gears, gear meshing driven rack walking push rod connected with the rack support rollers supported by synchronous walking, you can achieve shade net extension and retraction of such action. Pull the rack and pinion drive system is in large curtain Connected Greenhouse, often in the form of external shading system driver selection, the system running smoothly, safe and reliable. In this system, geared motor drive shaft driven by gears, gear racks make linear reciprocating motion, push the lever on the rack with the support rollers are connected via push rod reciprocating realization shade net expansion and collapsed.
