Description
Technical field
This utility model is related to machinery design field, more particularly to a kind of ratchet worm screw.
Background technology
Generally various different driving parts to be used, in these driving parts, some need to realize big transmission on lathe
Some need intermittent movement, worm and gear and click is to realize the conventional part of both transmissions to ratio respectively, traditional biography
The transmission of flowing mode both is fabricated separately, and takes up room big during installation, the high cost being fabricated separately, transmission trouble, efficiency
Low, due to unreasonable structure so that the part matching is fragile during design, poor stability, ratchet working end angle is big, causes
The low intensity of ratchet, fragile, therefore design a kind of structure simply, low cost, transmission is convenient, efficiency high, the part matching
It is hardly damaged, safety is good, transmission is smooth, the intensity of ratchet is high, and non-damageable ratchet worm screw seems very necessary.
Utility model content
The purpose of this utility model is to be fabricated separately to overcome traditional kind of drive both to be driven, cost
Height, transmission trouble, efficiency is low, poor stability, and the flimsy defect of ratchet devises a kind of ratchet worm screw, and structure is simple, cost
Low, transmission is convenient, efficiency high, and the part matching is hardly damaged, and safety is good, and transmission is smooth, and the intensity of ratchet is high, not rapid wear
Bad.
The required technical problem solving of this utility model can be achieved through the following technical solutions：
A kind of ratchet worm screw, including worm shaft, axis hole, described worm shaft is cylindrical structure, and its center is drilled with described axle
Hole, described worm shaft is arranged on transmission shaft of machine tool by this hole, also includes the gear teeth, ratchet, and gear teeth processing described in worm screw exists
On the excircle of described worm shaft, engage with turbine and transmit motion to turbine wheel shaft, process on the end face of described worm shaft
There is described ratchet, during described worm shaft, described ratchet can promote the pawl wheel engaging on the left of it, realizes ratchet
The intermittent movement of axle.
The equal chamfer machining of all sharp edges of described ratchet shaft becomes 0.5 × 45 °.
The thread form angle of the described gear teeth takes 40 °, is straight line positioned at the profile of mid-plane Nei Qiya.
Described ratchet is the steel alloy processing through high-frequency quenching, and its hardness number is up to HRC45～50.
The working end profile angle of described ratchet is 3 °.
Due to employing above technical scheme, this utility model has the advantage that：
Ratchet worm screw designed by being combined using worm shaft, axis hole, the gear teeth, ratchet, all sharp edges of ratchet shaft all fall
Angle is processed into 0.5 × 45 °, and the part matching is hardly damaged, and safety is good, and the thread form angle of the gear teeth takes 40 °, positioned at mid-plane
The profile of Nei Qiya is straight line, meets the engaged transmission condition of master worm wheel worm screw, and transmission is smooth, and ratchet is through high-frequency quenching
The steel alloy processing, up to HRC45～50, the intensity of ratchet is high, and bearing capacity is strong, the working end profile angle of ratchet for its hardness number
For 3 °, the thickness of ratchet is big, and when promoting ratchet work, ratchet is hardly damaged.
