Processing involute bevel gears with hobbing machine

As is known, ordinary hobbing machines can only process involute spur or helical gears and cannot process involute bevel gears. The main reason is that the ordinary hobbing machine hob cannot be fed radially relative to the workpiece, or the radial feed and axial feed of the hob cannot be performed at the same time. To machine a taper gear, the gear hobbing machine should have four basic movements: the rotary motion of the hob around its own axis.

Site Selection for Mass Flow Meter Installation
a) Sensor stays away from mechanical vibration source, for example, pump. Use flexible pipe to connect meter with pipeline if inevitable. The housing of meter must be standalone, out of touch with any other device. There must be 3 times the size of sensor between 2 sensors if there are many flow meters on the same pipeline, to avoid resonance.
b) Do not install sensor on pipeline that easily expands with hot and contracts with cold, especially near expansion joint, which leads to a worse stability.
c) Sensor stays away from industrial electromagnetic field, such as large generator and transformer, better 5m at least. Such device influences the performance of drive coil and pickoffs. Make sure magnetic field intensity less than 400A/m.
d) Sensor shall be installed on lower pipeline, to be easily full of fluid.
e) Make sure Ex-mark meet application requirements if in hazardous area.
f) Build a sunshade if the meter is under direct solar radiation. g) Keep the meter from corrosive liquid.
