Manufacturing and assembly spur a lot of flakes is both difficult and uneconomical, and therefore manufactured integral gear teeth along the helical direction of the gear. Helical gear is not as straight, it will lead to undesirable axial force. But the benefits in terms of vibration and strength far better than the disadvantage caused by the axial thrust and a slight increase in manufacturing costs brought. So use helical gear rather than straight gear reducer such as the manufacture of four series:. R series coaxial helical gear reducer, K series of spiral bevel gear reducer, S series helical worm gear reducer, F series parallel shaft helical gear reducer. Adjust the rolling bearing: rolling bearing rolling elements between the inner and outer ring a certain gap, the gap is too big prone to vibration and noise, but the gap is too small, easily lead to severe heat and wear. Both will shorten bearing life. Rolling into an adjustable gap is not adjustable in two. Non-adjustable bearing clearance (eg radial ball bearings), it has been given clearance to ensure that during manufacture. But using different gear maintenance standard conditions, axis thermal expansion of Beijing gear maintenance, axial movement, the bearing clearance reduction Tianjin reducer maintenance, even the rolling bodies stuck. Therefore, when such a bearing assembly, a bearing fixed, the other end of the shaft between the bearing and the end cap leaving an axial gap, and its value is generally between 0.25 to 0.5 mm (excluding high-temperature environment).
