Mineral product monorail reduction gear synopsis
1 what is reducer
Reducer is a dynamic communication agencies, the u of gear speed converters, motor rotational speed reducer to the Rotary to be few, and have greater torque institutions.
1.1 The reducer role
1.1.1 velocity at the same time increa the output torque, torque output ratio by motor output by slowdown, but the attention should be paid to exceed the rated torque reducer.
1.1.2 the speed at the same time reduce the inertia load, the inertia of deceleration than reduced to the square. We can look at the General Motors has a value of inertia.
1.2 The type of reducer
General helical gear reducer has reducer (including parallel shaft helical gear reducer, a worm reducer, bevel gear reducer, etc.), planetary gear reducer, Cycloid reducer, a worm reducer, a planetary friction CVT mechanical machines.
1.3 Common reducer
1.3.1 worm reducer is the main characteristics of a rever lf-locking function, can be larger than a slowdown, input shaft and output shaft axis is not the same, nor in the same plane. But generally larger, transmission efficiency is not high, the accuracy is not high.
1.3.2 Harmonic Drive reducer is controllable using flexible components to transfer elastic deformation and dynamic movement, not volume, high precision, but the disadvantage is that flexible wheel limited life, impatient shocks, rigidity and pieces of metal relatively poor. Not too high speed input.
1.3.3爱好的英文 planetary reducer its comparative advantage is compact structure, the return gap small, high precision, and have a long life span rated output torque can be done great. However, a price slightly expensive, the requirements of parts before asmbly ：
1.3.3.1 Rolling cleaning with gasoline, kerone other parts cleaning. All parts and cabinet not allowed to have any impurities exist. Gear box and the inner wall (Worm), unprocesd surface has not been coated twice erosion-resistant oil paint box has the outer surface coated primer and paint color (color requested by host).
1.3.3.2 Parts coated with a face wash after lubricants.
2 the requirements of installation and adjustment
2.1 Rolling installation
Rolling bearing inner ring should be installed at the shaft shoulder clo to gap must not pass 0.05 mm thick Cypriot feet.
2.2 Bearing axial clearance
wait and e
Of the clearance can not be adjusted bearings (such as deep groove ball bearings), axial clearance of 0.25 to 0.4 mm; the clearance adjustable bearing axial clearance numerical t
able. Click Tapered Roller Bearings axial clearance; angular contact ball bearing axial clearance.
2.3 Gear (Worm) meshing tooth space available
lrcp
Cypriot side foot of lead or pressure. Will be lead wire on the alveolar, and then turning gear and squash lead wire, measuring two teeth side was crushed lead wire thickness and the size of which is adjacent teeth.
2.4 Tooth contact dot cylinder gear tooth contact Dot 2-10-4; bevel gear tooth contact Dot 2-11-4; Gearing contact Dot 2-12-4explosion.blackness
3 al requirements
3.1 Box partition between the surface does not allow any pads filled, but can be coated or water glass alant to ensure that the al;
3.2 Asmbly, the bolt tightening box, before using 0.05 mm Cypriot-foot inspection Covers Block with me and between the aling surface;
3.3fingering Shaft al should stretch to smear grea. The al should be installed in strict accordance with the requirements.
4 lubrication requirements
4.1 Rationally determine the types of lubricants and greas and grades
4.2 Bearing lubrication fat, grea filled in the general Fatliquor space can be 1 / 2 to 2 / 3.
4.3greatbritain Lubricants should be regularly replaced, the new reducer ud for the first time, the operation of oil-7 ~ 14 days, according to the situation can be after every 3 to 6 months for first oil.
5 the test requirements
5.1 Empty operation: at rated speed is, anti-running 1 to 2 hours;
5.2 Load test: at rated speed, rated load operation, the oil temperature balance to date. On the gear reducer, requested the pool temperature is not more than 35 , bearing temperature ri no more than 40 scm是什么意思; the worm reducer, requested the pool temperature not more than 60经典英语散文, bearing temperature of not more than 50 software是什么意思.
