The driving mechanism of present existing speed reducer generally all is made up of worm and wheel, and an end and the worm gear of worm screw mesh together, and the other end links to each other with motor, and a rotatingshaft is set in the worm gear.The working principle of transmission is such, and by the rotation of driven by motor worm screw, worm screw drives the worm gear that meshes together with it more then, the rotation of last worm gear drives rotatingshaft, and rotatingshaft is linking to each other with the equipment of other required application.And worm screw in the market all is single helical pitch worm screw, single helical pitch worm screw has advantage of simple structure, yet so single helical pitch worm screw transmission speed in work is slower, make the working efficiency of speed reducer be difficult to improve, and single helical pitch worm screw can produce certain wearing and tearing in use for some time, makes having some setbacks that transmission becomes.
Summary of the invention
The purpose of this utility model is that the Worm and Worm Gear Driving mechanism at existing speed reducer exists above-mentioned problem, provides that a kind of transmission speed is fast, the transmission Worm and Worm Gear Driving mechanism of speed reducer more smoothly.
The purpose of this utility model can realize by following technical proposal: a kind of Worm and Worm Gear Driving mechanism of speed reducer, worm gear and worm screw all are arranged in the casing of speed reducer, worm and wheel engagement and worm screw link to each other with power mechanism, an also sheathed rotatingshaft in the described worm gear, it is characterized in that described worm screw is many helical pitches worm screw.
The working principle of the Worm and Worm Gear Driving mechanism of this speed reducer is such, worm gear and worm screw all are arranged in the casing of speed reducer, end of worm screw and worm gear engagement, an other end links to each other with power mechanism, an also sheathed rotatingshaft in the worm gear, power mechanism drives the rotation of worm screw, and worm screw drives the worm gear that meshes together with it more then, the rotation of last worm gear drives rotatingshaft.And the worm screw of the Worm and Worm Gear Driving mechanism of this speed reducer is many helical pitches worm screw, makes transmission speed faster, more smooth and easy.
In the Worm and Worm Gear Driving mechanism of above-mentioned speed reducer, described worm screw is two helical pitch worm screws.Make that by two helical pitch worm screws the Worm and Worm Gear Driving mechanism driving speed of speed reducer is faster, more smooth and easy.
In the Worm and Worm Gear Driving mechanism of above-mentioned speed reducer, also be provided with a shoe cream room between the described worm and wheel, have a filler opening that passes housing on the described shoe cream room.By the oil in the shoe cream room worm and gear is lubricated, makes the transmission better effects if.
In the Worm and Worm Gear Driving mechanism of above-mentioned speed reducer, also be arranged with bearing on the described rotatingshaft.By bearing rotatingshaft is fixed, rotatingshaft be can with boats and ships, automobile, locomotive, heavy facility for building link.
In the Worm and Worm Gear Driving mechanism of above-mentioned speed reducer, described power mechanism is a motor, and the above-mentioned worm screw and the output shaft of motor link.The work of motor drives the rotation of worm screw again by motor output shaft.
As another situation, in the Worm and Worm Gear Driving mechanism of above-mentioned speed reducer, described power mechanism is a motor, and the above-mentioned worm screw and the output shaft of motor link.The work of motor drives the rotation of worm screw again by motor output shaft.
Compared with prior art, the Worm and Worm Gear Driving mechanism of this speed reducer adopts the driving mechanism of two helical pitch worm screws as speed reducer, and is simple in structure, transmission speed is faster, transmission is more smooth and easy.
