Technical requirements for the installation, use, maintenance, etc. of the reducer

One of the requirements of parts before assembly

1, rolling bearing cleaning with gasoline, kerosene and other parts cleaning. All the parts in the box and no impurity. The unmachined surface, such as the inner wall of the box and the gear (worm wheel), has been painted two times without oil erosion. The surface of the box is painted on the surface of the box and painted with color (color according to the requirements of the host).

2, parts coated with a face wash after lubricating oil

Two, the requirements of installation and adjustment

1, rolling bearing installation

Rolling bearing inner ring should be installed at the shaft shoulder close by 0.05mm thick seam required no feeler.

2, bearing axial clearance

The bearing clearance is not adjustable (such as deep groove ball bearings), the axial clearance is 0.25-0.4mm; bearing axial clearance numerical the clearance adjustable table. Click to view the tapered roller bearing axial clearance; angular contact ball bearing axial clearance

3, gear (worm) meshing backlash

The available lead or pressure gauge. The lead wire on the slot, then turning gear and squash leadwire measuring two flank was crushed lead wire thickness and the size of which is adjacent teeth.

4, the tooth contact dot cylinder gear tooth contact dot 2-10-4; bevel gear tooth contact dot 2-11-4; the contact spot of 2-12-4 worm drive

Three, sealing requirements

Between the 1 and the box section does not allow any padsfilled but can be coated with sealant or glass of water to ensure the sealing;

2, the assembly, the bolt tightening box before, should check the box cover using 0.05mm feeler and the box seat with sealing surface between the;

3, shaft seal should be coated with grease. The seal should be installed in strict accordance with the requirements

Four, lubrication requirements

1, reasonably determine the lubricating oil and grease type and grade

2, bearing grease lubrication, the filling amount of lubricating grease can be generally fat space 1/2-2/3.

3, the lubricating oil should be replaced regularly, the new reducer is used for the first time, 7-14 days after the operation of oil, according to the situation of every 3-6 months for a oil.

Five, test requirements

1, no-load operation: at rated speed, running 1-2 hours;

2, load test: run at rated speed, rated load, oiltemperature balance to date. For gear reducer, the oil pool temperature rise not more than 35oC, bearing temperature rise not more than 40oC; for worm gear reducer, the oil pool temperature rise not more than 60oC, bearing temperature rise not more than 50oC; 3. all test process, the smooth operation, small noise, connecting the fixed place not loose, the seal, the combination is not loose

Six, packing and shipping requirements

1, extended shaft and accessories should be oiled packaging;

2. The technical requirements for the lifting and lifting of the hoisting screw and the lifting ear are not necessarily all listed, and the additional items are sometimes required, mainly depending on the specific requirements of the design.

Seven, technical requirements

1, before the assembly, all parts cleaning with kerosene, gasoline cleaning bearings, no debris exist. Oil is not painted wall corrosion coatings two;

2, with the lead wire backlash test of not less than 0.16mm, the wire not greater than 4 times the minimum clearance;

3, color dot test. According to the tooth contact point of not less than 40%; contact spots on teeth not less than 50%. Can be used when necessary grinding or scraping after grinding to improvecontacts4;

4, should adjust the bearing axial clearance: diameter 40 0.05-0.1mm, with 55 0.08-0.15mm;

5, test reducer subdivision surface contactsurface and seal oil spills are not allowed. The split surface allows coated with paint or water glass seal and allow the use of any filler;

N100 lubricating oil to the required height, with 6 frame.
