Description
Technical field
The present invention relates to machinery design field, particularly relate to a kind of ratchet worm screw.
Background technology
Generally to use various different driving parts on lathe, in these driving parts, some needs to realize big transmission
Ratio, some needs intermittent movement, worm and gear and click to be to realize the part that both transmissions are conventional, traditional biography respectively
Flowing mode both transmissions are fabricated separately, and take up room big during installation, and the cost being fabricated separately is high, and transmission bothers, efficiency
Low, make the part matched fragile due to unreasonable structure during design, poor stability, ratchet working end angle is big, causes
The intensity of ratchet is low, fragile, therefore a kind of simple in construction of design, low cost, and transmission is convenient, and efficiency is high, the part matched
Being hardly damaged, safety is good, and transmission is smooth and easy, and the intensity of ratchet is high, and non-damageable ratchet worm screw seems the most necessary.
Summary of the invention
The purpose of the present invention is contemplated to overcome traditional kind of drive both transmissions to be fabricated separately, and cost is high,
Transmission bothers, and efficiency is low, poor stability, the flimsy defect of ratchet, devises a kind of ratchet worm screw, simple in construction, low cost,
Transmission is convenient, and efficiency is high, and the part matched is hardly damaged, and safety is good, and transmission is smooth and easy, and the intensity of ratchet is high, is hardly damaged.
Solve the technical problem that required by the present invention and 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 i.e. 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, be positioned on the end face of described worm shaft processing
Having described ratchet, during described worm shaft, described ratchet can promote the pawl wheel engaged on the left of it, it is achieved 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 °, and the profile being positioned at mid-plane Nei Qiya is straight line.
Described ratchet is the steel alloy processed through high-frequency quenching, and its hardness number is up to HRC45～50.
The working end profile angle of described ratchet is 3 °.
Owing to have employed above technical scheme, present invention have the advantage that
Using the ratchet worm screw that worm shaft, axis hole, the gear teeth, ratchet combine designed, all sharp edges of ratchet shaft all fall
Angle is processed into 0.5 × 45 °, and the part matched is hardly damaged, and safety is good, and the thread form angle of the gear teeth takes 40 °, is 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 easy, and ratchet is through high-frequency quenching
The steel alloy processed, its hardness number is up to HRC45～50, and the intensity of ratchet is high, and bearing capacity is strong, the working end profile angle of ratchet
Being 3 °, the thickness of ratchet is big, and when promoting ratchet work, ratchet is hardly damaged.
