Training skilled bearing managers


Product quality, a process to ensure a scientific, but also have high-quality management personnel to implement. Antirust management is "prevention" and take preventive measures, will produce metal corrosion factor nipped in the bud, and which requires skilled, with high-quality management personnel.

First, truck mounted crane bearing managers are required to have anti-rust metal corrosion basic theoretical knowledge, have a certain level of expertise, the importance of anti-rust management have a full understanding, there is a high degree of responsibility, anti-rust process specification can conscientiously implement and carry out supervision carried out.

For example, requiring antirust level managers must have a college degree, a metal corrosion expertise, familiar with the bearing processing the entire process, all bearing rust can develop technical rules, with a production deal with and solve problems arise the actual ability, training and work instructions antirust members.

Owned manufacturing plant for rust prevention officer asked two must have a high school education, after induction by the technical department for their technical training, basic theoretical knowledge from rust-proof, rust-proof technology content and operation points and rust-proof materials during use detection and monitoring methods to the importance of anti-rust work, so that they improve their professional skills by learning antirust comprehensive system to enhance awareness of disease prevention, according to the company's leading technology can apply the knowledge learned documents, combined with the specific units case for the unit to work out specific antirust rules; each member of every able-rust-site inspections, monitoring the implementation of anti-rust process, the general anti-rust problems can be analyzed and timely processing solutions, that can not be resolved problems promptly report to their superiors technology sector, cooperative solutions; and is able to project accurately monitored regularly testing according to process requirements. So a team of professional technical and management training is very necessary.

Formulate scientific management methods

Management is a concrete manifestation of anti-rust management, saying no rules, no standards, good scientific management is an important means to ensure product quality. Antirust management including process management, cooling water management, anti-rust solution management, cleaning vertical mill bearing fluid management, anti-rust oil management and rust auxiliary materials management. Los axis using two anti-rust management system, at the level of anti-rust technology management department, responsible for the development and centralized management of anti-rust process, responsible for anti-rust auxiliary materials testing and inspection, is responsible for technical guidance rustproof member responsible antirust work for secondary management assessment, and rust-proof new technology, research and development and application of new technologies.

Double row ball slewing bearingand shaft installation inspection method

In general, tight interference fit the installation of double row ball slewing bearing must be close to the shaft shoulder. Test method: (1) the light method. The lamp alignment Koyo bearings and shaft shoulder, see the leakage judgment. If no leakage, installation is correct; if the light evenly along the shaft shoulder around, the bearing and shaft shoulder is not close, with the pressure bearing close; if partial leakage, the bearing installation tilt, can be hand hammer, brass or percussion bearing inner ring sleeve, is slowly. (2) to test the feeler gauge. Feeler gauge thickness shall be 0. 03mm began. Test, test in several in the bearing inner ring end face and shoulder the entire circumference, if there is a gap and very uniform, indicating that miniature ball bearings is not installed in place to deal with bearing, double row self-aligning ball bearing inner ring of pressure it tightly against the shoulder; if the increased pressure is not tight, the Journal fillet positions fillet is too large, the bearing is stuck, should be trimmed journal fillet, make its become smaller; if it is found that the end surface of the inner ring and the bearing shoulder thickness gauge individual parts can pass, not at this time must be removed, to be repaired, re install.
The principle of  lubricating bearings and three row roller slewing bearing are basically the same, only the bearing working condition is bad, its performance can achieve effective lubrication depends to a large extent on the bearing.
