1、. .英文原文：Mineral product monorail reduction gear synopsis1what is reducerReducer is a dynamic communication agencies, the use of gear speed converters, motor rotational speed reducer to the Rotary to be few, and have greater torque institutions. 1.1 The reducer rolevelocity at the same time increase
2、the output torque, torque output ratio by motor output by slowdown, but the attention should be paid to exceed the rated torque reducer. 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 inerti
3、a. 1.2 The type of reducerGeneral 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 reducerworm reducer is the m
4、ain characteristics of a reverse self-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. Harmonic Drive reducer is controllable using flexible
5、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. planetary reducer its comparative advantage is compact stru
6、cture, 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 assembly ：.1Rolling cleaning with gasoline, kerosene other parts cleaning. All parts and cabinetnot allowed to have any
7、impurities exist. Gear box and the inner wall (Worm), unprocessed surface has not been coated twice erosion-resistant oil paintbox has the outer surface coated primer and paint color (color requested by host). .2 Parts coated with a face wash after lubricants.2 the requirements of installation and a
8、djustment 2.1Rolling installationRolling bearing inner ring should be installed at the shaft shoulder close to gap must not pass 0.05 mm thick Cypriot feet. 2.2Bearing axial clearanceOf the clearance can not be adjusted bearings (such as deep groove ball bearings), axial clearance of 0.25 to 0.4 mm;
9、 the clearance adjustable bearing axial clearance numerical table. Click Tapered Roller Bearings axial clearance; angular contact ball bearing axial clearance.2.3Gear (Worm) meshing tooth space availableCypriot side foot of lead or pressure. Will be lead wire on the alveolar, and then turning gear a
10、nd 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 2-12-4.3 seal requirements 3.1 Box partition between the surfa
11、ce does not allow any pads filled, but can be coated or water glass sealant to ensure that the seal; 3.2 Assembly, the bolt tightening box, before using 0.05 mm Cypriot-foot inspection Covers Block with me and between the sealing surface; 3.3 Shaft seal should stretch to smear grease. The seal shoul
12、d be installed in strict accordance with the requirements.4 lubrication requirements 4.1 Rationally determine the types of lubricants and greases and grades 4.2 Bearing lubrication fat, grease filled in the general Fatliquor space can be 1 / 2 to 2 / 3. 4.3 Lubricants should be regularly replaced, t
13、he new reducer used 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 te
14、mperature balance to date. On the gear reducer, requested the pool temperature is not more than 35 , bearingtemperature rise no more than 40 ; the worm reducer, requested the pool temperature not more than 60, bearing temperature of not more than 50 .6 packaging and transportation requirements 6.1 P
15、rotruding shaft and its annex should Oiler packaging; 6.2 Handling, lifting may not use screw rings and lug all of the above technical requirements are not necessarily listed, and sometimes also by other projects, mainly by the specific design requirements. 7 Technical requirements 7.1 Assembly, all
16、 parts cleaning with kerosene, gasoline Rolling cleansing, while the existence of any debris. Oil is not painted wall corrosion coatings twice; 7.2 Backlash with lead wire mesh test of not less than 0.16 mm, lead wire Backlash may not exceed the smallest of the four times; 7.3 Used Tu-color dot test. Tooth high point of contact by not less than 40% of c
