Description
Technical field
The invention belongs to turntable bearing, particularly to a kind of turntable bearing with angle measurement system.
Background technology
It is known that developing rapidly along with science and technology, the turntable bearing grown up of recording modern times, increasingly it is applied to all trades and professions. This is because this turntable bearing has height axially and radially bearing capacity, high dip rigidity, also there is high precision simultaneously, be particularly well-suited to the Bearing configuration in rotary table, chuck and ferrum cutter head and measurement and experimental facilities; Its structure includes seat ring, blowout patche, packing ring, retainer assembly and several cylindrical rollers composition. Seat ring and blowout patche have uniform installation screw hole, are fixed between corresponding parts by these screw holes by bearing, it is achieved gyration. In recent years, pursue manufacture along with the increasingly mature and people producing turntable bearing product manufacturing technology and there is the turntable bearing of higher precision; More external bearing manufacturer have been carried out being integrated on turntable bearing angle measurement system, form a kind of new turntable bearing with the system of measurement, and the YRTM series of products such as Germany INA/FAG are exactly the turntable bearing that integrated angle measures system. It is to be produce additional magnetic size scale on the excircle of the packing ring of bearing. So, end ring is equivalent to a magnetic railings ruler, and the same with magnetic railings ruler angular encoder principle, measurement system can realize contactless angular surveying, and precision can reach several rad. The advantage of this angle measurement system is: measurement system is operated and thus without abrasion by contactless mode; Install, adjust simple and convenient; Compact conformation, it is not necessary to additional sensor fixing structure, saves space; The installation site of measurement system is close to revolving support unit, and the installation rigidity measuring system reaches to maximize; Can pass through to measure system balance bearing alignment error, can further improve bearing unit rotating accuracy. The shortcoming of the YRTM turntable bearing of this form is: processing high-precision magnetic size scale technology on the back-up ring of bearing and require high, difficulty of processing is big, and cost is high; Additionally magnetic railings ruler has the phenomenon being prone to be demagnetized by other magnetic materials or destroyed by the magnetic field in environment, and easily by electromagnetic interference, has hysteresis. Therefore, working environment even installation tool, installation method, in the code installed and used, are had strict requirement, limit its range of application by this turntable bearing.
Summary of the invention
It is contemplated that in order to avoid the shortcoming and defect part existed in above-mentioned technology, it is provided that a kind of turntable bearing with angle measurement system; This invention adopts the angular encoder angle measurement system as turntable bearing of the vicarious without any magnetic part; On market, this kind of product sensor is a lot, technology maturation. Installing circular steel grid chi on turntable end ring excircle, steel grid chi is a ring stainless steel band, is carved with high-precision grid above. The advantage of this measurement system: system of measuring, based on the transformer working principle with magnetic resistance core, does not comprise any magnetic material, not by electromagnetic effect, hysteresis will not occur, dangerous without demagnetization; Degree of protection high (IP67), opposing harsh environments ability is strong.
It is an object of the invention to adopt the following technical scheme that realization: the described turntable bearing with angle measurement system, packing ring including turntable bearing, it is characterized in that: the outer circumference surface being close to turntable bearing washer connects steel grid chi by seam or step, on the lateral surface of described steel grid chi, size scale is carved with in distribution, installing the measurement head of more than one angular encoder on the blowout patche end face corresponding with the size scale position of steel grid chi, described each measurement head is supported by the cushion block on blowout patche end face; The signal that its measurement head is measured is connected with signal processor by wire, and its signal processor is connected with computer by wire.
Described steel grid chi adopts rustless steel to make.
Principles of the invention and operation are described below:
The present invention is the step or seam that process on the packing ring of turntable bearing and install steel grid chi. Angle measurement system includes two and measures head, a cushion block and an E-signal processor. It is measured head and is arranged on the blowout patche of turntable bearing, is measured the distance between head and steel grid chi by pad adjustment. Its signal measuring head is processed by signal processor, and the control system of computer is arrived in output. Installing circular steel grid chi on turntable bearing washer excircle, steel grid chi is a ring stainless steel band, is carved with high-precision grid above. The advantage of this measurement system: system of measuring, based on the transformer working principle with magnetic resistance core, does not comprise any magnetic material, not by electromagnetic effect, hysteresis will not occur, dangerous without demagnetization; Degree of protection high (IP67), opposing harsh environments ability is strong, is widely used.
The comprehensive above technical scheme taked, it is achieved the purpose of the present invention.
Compared with prior art, the structure of the present invention is not only reasonable in design, compact conformation, neither by electromagnetic effect, hysteresis will not be there is again, dangerous without demagnetization, and there is degree of protection height (IP67), opposing harsh environments ability is strong and uses the advantages such as very convenient.
