Composition and application

Parallel shaft geared motor is made up of two or three bevel gears, which are related to the deceleration ratio, in the same box. A total of 11 parallel helical gear reducers with a torque range of 3 to 22500NM. The maximum output power of the motor is 200KW.
The transmission ratio range of parallel shaft geared motor ranges from I =3.77 to I = 31434. Extremely low output speed (a multi-stage reducer with an additional inclined gear input class).
Products are widely used in light industry, food, beer, beverage, chemical, escalators, automatic warehousing equipment, construction, machinery, iron and steel, metallurgy, papermaking, man-made board machinery, automobile manufacturing, tobacco machinery, water conservancy, printing and packaging, pharmaceutical, textile, building materials, logistics, feed machinery, environmental protection and other fields.

B Helical Bevel Gearbox

B helical bevel Gear Units is a brand-new model of rigid tooth flank gear reducers with wide application areas,which has the feature of large torque range, a design of unit structure modulization capable of horizontal mountingand vertical mounting, three kinds of output shafts --- solid shaft, hollow shaft and hollow shaft with shrink disk. 

With carbureted high-strength good-quality alloy, the series has the feature of high-efficiency and long life-span, high permissible axial and radial loads, low noise, high reliability and compact structure and so on.

The difference between helical bevel gear and hypoid bevel gear

Helical bevel gears and quasi-hyperboloid bevel gears are the main driving modes of automobile main reducers. What's the difference?
Helical bevel gears as shown in figure 2 (a), the main, driven gear axes intersect in one point, Angle can be arbitrary, but in most of the automobile drive axle, the main reducer gear pair with 90 ° Angle of vertical arrangement. Because of the influence of the tooth face overlap, more than there are at least two pairs of tooth mesh at the same time, as a result, the spiral bevel gear can bear larger load, together with its tooth not to nod in the whole tooth meshing at the same time, but gradually from one end of the tooth row to the other end, making the work is smooth, even at high speed, noise and vibration is very small.
Hypoid gear as shown in figure 2 (b), the main, driven gear axis of disjoint and space of the cross, the space also use 90 ° Angle more crossing Angle different surface vertical way. The active gear shaft has an upward or downward offset relative to the driven gear shaft (appropriately called the upper or lower offset). When the offset is large enough, a gear shaft is passed by the other shaft. So you can in each gear bearing on either side of the size compact, to strengthen the support stiffness, guarantee the tooth meshing correctly, so as to improve gear life is good, it is suitable for the type of drive axle.
Fellowship with due to the axis of the gear pair of helical bevel gears and make the winner and driven gear equal helix Angle is different, the axis of the hypoid gear pair migration makes the driving gear helix Angle is greater than the driven gear spiral Angle. Therefore, the method of the quasi-hyperboloid bevel gear pair is equal, but the end surface modulus is unequal (the end face modulus of the active gear is greater than that of the driving gear). This makes the driving gear of the quasi-double-sided bevel gear has a larger diameter and better strength and stiffness than the corresponding helical bevel gear drive. In addition, due to the large diameter and spiral Angle of the driving gear of the hypoid bevel gear drive, the contact stress of the tooth surface is reduced and the life span is increased.
But the transmission comparison hour, the driving gear of the quasi-double-sided bevel gear is too large for the driving gear of spiral bevel gear, and the helical bevel gears is more reasonable.

Merits and demerits

The helical gear box are used in both high power gear reducer and small power gear reducer, and the helical gear box has an irreplaceable role on some occasions. Let's analyze the advantages and disadvantages of the lower helical gears:
The advantages of the Helical Bevel Geared Motors: the minimum number of teeth is not produced. The high degree of recombination reduces the load of each gear and improves the bearing capacity of the gear. Good meshing is stable, low noise.
Rack of helical gear faults: compact structure, in shape cutter cutting helical cylindrical gear, its no root cutting standard gear, the minimum number of teeth is less than the spur gears, thus can get a more compact structure; Contact ratio is big, under the same conditions, the helical gear meshing process is longer than straight gear, the contact ratio is bigger, this reduces the load capacity of each pair of gear, so as to improve the bearing capacity of the gear, prolong the service life of the gear, and smooth transmission; Human type gear manufacturing is troublesome, manufacturing process is complicated, cost is high.

Tips of spiral Helical Worm Gearmotors maintenance

1、New screw and helical worm gearmotors, when using in turn even after 300 hours, need to change new oil, then each used 2500 hours needs an oil change, but still in use process should be regularly check the oil quality, if the oil has impurities, aging, metamorphism, must be replaced at any time.
2、Helical worm gearmotors should use fixed brand and number gear oil, and should not mix different brands, Numbers or different types of oil. In the process of oil change, clean the inside of the reducer first and then inject new oil./3、During use, if I found the oil temperature is too high (more than 80 ℃), and abnormal phenomenon such as noise, should immediately stop using, to check the reason. After troubleshooting or replacing the lubricant, you can continue to use it.
4、If extreme cold as below 10 ℃, temperature should be considered in the selection of the ring on the influence of the speed reducer, can consider the configuration of electric heater and so on, this is very important for the worm gear reducer lubrication maintenance, regular observation of oil level movements, observe whether the vibration and noise have without exception.
  The correct maintenance USES spiral worm gear motor, can maximize its function.
