Copper gear stainless steel small modulus car pedal worm gear
assembly.
Description
The worm gear structure is commonly used to transmit the motion and
power between two interleaved shafts. The worm wheel and the worm
are equivalent to the gear and the rack in the middle plane, and
the worm and the screw are similar in shape.
Modulus m, pressure angle, worm diameter coefficient q, lead angle,
number of worm heads, number of worm gear teeth, addendum height
coefficient (take 1) and head clearance coefficient (take 0.2).
Among them, the modulus m and pressure angle refer to the modulus
and pressure angle of the worm shaft surface, that is, the modulus
and pressure angle of the end face of the worm wheel, and both are
standard values; the worm diameter coefficient q is the worm index
circle diameter and its modulus The ratio of m.
Institutional characteristics
1. A large transmission ratio can be obtained, which is more
compact than the cross-shaft helical gear mechanism.
2. The meshing tooth surfaces of the two wheels are in line
contact, and its load-bearing capacity is much higher than that of
the cross-axis helical gear mechanism.
3. The worm drive is equivalent to a spiral drive, which is a
multi-tooth meshing drive, so the transmission is stable and the
noise is small.
4. Has self-locking. When the lead angle of the worm is smaller
than the equivalent friction angle between the meshing gear teeth,
the mechanism is self-locking and can realize reverse self-locking,
that is, only the worm can drive the worm wheel, but the worm wheel
cannot drive the worm. For example, the self-locking worm mechanism
used in hoisting machinery, its reverse self-locking property can
play a safety protection role.
5. The transmission efficiency is low and the wear is serious. When
the worm gear is engaged in transmission, the relative sliding
speed between the meshing gear teeth is large, so the friction loss
is large and the efficiency is low. On the other hand, the relative
sliding speed means that tooth surface wear is serious and heat is
serious. In order to dissipate heat and reduce wear, more expensive
materials with better anti-friction and anti-wear properties and
good lubricating devices are often used, so the cost is higher.
6. The axial force of the worm is relatively large.
