2, after the parts cooperation surface is cleaned and coated with smooth oil II, equipment and adjustment requirements 1. Rolling bearing equipment rolling bearing equipment should be close to the shoulder of the bearing; the demand gap must not pass 0. 05mm thick feeler.
2. The bearing with axial clearance can not adjust the clearance (such as deep groove ball bearing); its axial clearance is 0. 25~0. 4mm, and the axial clearance of the bearing can be adjusted. Click to view the axial clearance of the tapered roller bearing, the axial clearance of the angular contact ball bearing 3, the tooth side clearance of the gear (worm gear) meshing can be placed on the tooth groove by the feeler gauge or the lead-pressing method; then the gear is changed And flattening the lead wire; measuring the sum of the thickness of the flattened lead wire on the two teeth side is the size of the flank.
4, tooth surface touch mottled cylindrical gear tooth surface touch mottle 2-10-4, bevel gear tooth surface touch mottle 2-11-4, worm drive touch mottle 2-12-4
Third, the sealing needs 1. No gaskets are required between the split faces of the cabinet; however, sealants or water glass can be applied to ensure sealing.
2. When the equipment is tightened; before tightening the bolts of the box; use a 0. 05mm feeler gauge to check the tightness between the cover and the contact surface of the box.
3. The shaft extension seal should be coated with smooth grease. The sealing equipment should be strictly according to the requirements. Equipment 4, smooth demand 1. Reasonable determination of smooth oil and smooth grease type and trademark 2. When the bearing grease is smooth; the filling amount of smooth grease is usually added. 1/2~2/3 of the lipid space.
3. Smooth oil should be replaced regularly; when the new reducer is used for the first time; change oil after 7~14 days of work; in the future, it can be changed every 3~6 months according to the situation.
V. Experimental requirements 1. No-load work: 1~2 hours of positive and negative work at extra speed.
2. Load test: work under extra speed and extra load; stop to oil temperature balance. For gear reducer; demand oil pool temperature rise does not exceed 35oC, bearing temperature rise does not exceed 40oC, worm reducer; demand oil pool temperature The rise does not exceed 60oC, the bearing temperature rise does not exceed 50oC, 3. In the course of all experiments; the demand work is stable; noise. Wutan ùΣ 啥桓髅芊狻 啥桓髅芊狻 å²· å²· 〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠〠ã€
2, the use of lifting ring screws and lifting lugs should not be used in the transfer or lifting, not necessarily in full; sometimes additional items are required; mainly based on the specific needs of the depiction.
Seven, skill needs 1, equipment; all parts are removed with fire oil; rolling bearings are cleaned with gasoline; no debris is allowed. The inner wall is coated with paint that is not corroded by oil.
2. The lead wire for the meshing backlash is not less than 0.16 mm; the lead wire shall not be greater than 4 times the minimum backlash.
3, using the coloring method to check the mottle. According to the tooth height touch point is not less than 40%, according to the tooth length touch mottled not less than 50%. If necessary, grinding or scraping can be used to improve the touch condition.
4. The axial clearance of the bearing should be adjusted: φ40 is 0. 05--0. 1mm, φ55 is 0. 08--0. 15mm;
5. Check the split surface of the reducer, the touch surfaces and the seals; no oil leakage is allowed. The split surface should be coated with seal paint or water glass; no filler is allowed to be used.
6. The base is equipped with N100 smooth oil to the regular height.

ABS Toilet Flush Panel features:
Beautiful Appearance: ABS flush panels offer the advantage of customizable designs and colors to suit the customer's preferences and the overall aesthetic of the bathroom. This allows for a visually appealing Toilet Tank panel.
Strong Durability: ABS material is known for its excellent durability. It can withstand prolonged use without deforming or losing its original shape. Additionally, ABS does not easily discolor over time, ensuring that the flush panel maintains its attractive appearance.
Easy to Clean: The smooth surface of ABS material makes it easy to clean. Regular wiping or cleaning with a soft cloth or sponge can effectively remove dirt, stains, or residue, keeping the toilet flush panel looking clean and well-maintained.
Easy Installation: ABS toilet push buttons are lightweight, which simplifies the installation process. They can be easily installed onto the water tank without the need for complex tools or equipment. This convenience saves time and effort during the installation process.
Strong Corrosion Resistance: ABS water tank panels exhibit excellent resistance to corrosion. They are not susceptible to damage from chemical substances or water erosion. This quality ensures the longevity and reliability of the flush panel, even in environments where exposure to water or cleaning agents is common.
In summary, ABS toilet tank panels offer a combination of aesthetic appeal, durability, ease of cleaning, and convenient installation. These features make ABS an excellent choice of material for toilet tank panels.
