Company Information

Product Description

  • Small transmission motor worm wheel and worm gear.Worm gear is a component of speed reducer of construction hoist.Worm gears are commonly used to transfer motion and power between two intersecting shafts. The worm gear and the worm in the middle plane are equivalent to the gear and the rack, and the worm is similar to the screw shape.

  • A Basic parameter

    Modulus m, pressure angle, worm diameter coefficient Q, lead angle, worm head number, worm gear number, addendum coefficient (take 1) and top clearance coefficient (take 0.2).

  • Among them, m modulus and pressure angle is the worm shaft surface modulus and pressure angle, i.e. turbine end modulus and pressure angle, and is the standard value; worm diameter coefficient q is the ratio of reference circle of worm diameter and modulus of M.Small transmission motor worm wheel and worm gear

  • B Classification

    There are roughly these series of worm gears:
    1, WH series worm gear reducer: WHT/WHX/WHS/WHC
    2, CW series worm gear reducer: CWU/CWS/CWO
    3, WP series worm gear reducer: WPA/WPS/WPW/WPE/WPZ/WPD
    4 ,TP series enveloping worm gear reducer: TPU/TPS/TPA/TPG
    5, PW type plane two enveloping hourglass worm reducer

    In addition, according to the shape of the worm, the worm drive can be divided into cylindrical worm drive, hourglass worm drive and cone worm drive.Small transmission motor worm wheel and worm gear

C Institutional features

1.A large transmission ratio can be obtained, which is more compact than an interlaced helical gear mechanism.

The line contact between the 2. pairs of meshing teeth is much higher than that of the crossed helical gear mechanism.

3. Worm drive is equivalent to screw drive, which is multi gear meshing drive, so it has stable transmission and little noise.

4. Self locking. When the guide angle of the worm is less than the equivalent friction angle between the meshing teeth, the mechanism has self-locking property and can realize reverse self locking, that is, the worm wheel can only be driven by the worm, and the worm wheel can not be driven by the worm wheel. If the self-locking worm mechanism is used in hoisting machinery, its reverse self-locking can act as a safety guard.

5.The transmission efficiency is low, wear more serious. When the worm and worm gears engage in the transmission, the relative sliding speed between the meshing teeth is large, so the friction loss is large and the efficiency is low. On the other hand, the relative sliding speed, tooth wear serious, serious heat to heat and reduce wear, often using expensive antifriction and good wear resistance materials and good lubrication device, so the cost is high.

6.The axial force of worm is larger.
