Is the standard spur gear the same type as the spur gear?
It can be said not the same kind. Can only be a class of products.What are the main differences between spur gears and helical gears?:1, because of the manufacturing error, the instantaneous speed of the spur gear is changing, mainly in the moment that the teeth meshing and meshing, resulting in uneven changes in speed due to manufacturing errors, resulting in polygon effect
The shape is different, for the following reasons:The modulus, the number of teeth and the pressure angle of the shifting gear are the same as that of the standard gear, and the dividing circle is the same as the standard gear. The addendum of the addendum shift gear increases, the root height decreases, the thickness of the indexing circle and the tooth thickness of the tooth root increase, and the addendum of the tooth tip is easy to change; the reverse gear is opposite.
3. The effect of the straight bevel gear and the spiral bevel gear in operation is different from that of the bevel gear:4. The spur gear is a two axis parallel drive5. The bevel gear is a two axis drive6 when the diameter of the pitch circle is not changed the torque on the shaft will not change.7, to say that the change is part of the force analysis of the teeth change:8. The normal gear of the bevel gear coincides with the tangential direction of motion9 、 the angle between the gear normal of the spiral bevel gear and the tangent of the movement always keeps a helix angle,10 、 the torque of the gear bears the product of =cos beta and torque
