Description
Technical field
The utility model belongs to the turntable bearing, particularly a kind of turntable bearing with angle measurement system.
Background technique
As everyone knows, along with the develop rapidly of science and technology, the turntable bearing that record and grow up modern times is applied to all trades and professions increasingly extensively.This is because this turntable bearing has high axially and radially bearing capacity, high dip rigidity, also has high precision simultaneously, is specially adapted to the bearing configuration in rotary table, chuck and iron cutter head and measurement and the experimental facilities; Its structure comprises seat ring, blowout patche, packing ring, retainer assembly and several cylinders roller composition.Seat ring and blowout patche have uniform installation screw hole, by these screw holes with bearing fixing between corresponding parts, realize rotation motion.In recent years, being accompanied by the increasingly mature and people that produce turntable bearing products manufacturing technology pursues manufacturing and has more high-precision turntable bearing; More external bearing MANUFACTURER have realized angle measurement system is integrated on the turntable bearing, form a kind of turntable bearing of new band measuring system, are exactly the turntable bearing of integrated angle measuring system as the YRTM series product of German INA/FAG.It is to be to produce additional magnetic size scale on the excircle at the packing ring of bearing.Like this, end ring just is equivalent to a magnetic railings ruler, and is the same with magnetic railings ruler angular encoder principle, and measuring system can realize contactless angle measurement, and precision can reach several rads.The advantage of this angle measurement system is: measuring system is operated by contactless mode and therefore can not worn and not torn; Install, adjust simple and convenient; Compact structure does not need the sensor fixing structure that adds, saves the space; The mounting point of measuring system is close to the revolution support unit, and the installation rigidity of measuring system reaches maximization; Can compensate the bearing alignment error by measuring system, can further improve the bearing unit rotating accuracy.The shortcoming of the YRTM turntable bearing of this form is: process high-precision magnetic size scale technology and require highly on the back-up ring of bearing, difficulty of processing is big, the cost height; Magnetic railings ruler has the phenomenon that is easy to be demagnetized by other magnetic materials or is destroyed by the magnetic field in the environment in addition, and is subjected to electromagnetic interference easily, and hysteresis is arranged.Therefore, this turntable bearing all has strict requirement to working environment even setting tool, installation method in the rules of installing and using, limited its application area.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, a kind of turntable bearing with angle measurement system is provided; This invention is adopted not with the angular encoder of the induction type of any magnetic part angle measurement system as the turntable bearing; This class product sensor is a lot of on the market, technology maturation.Circular steel grid chi is installed on turntable end ring excircle, and steel grid chi is a ring stainless steel band, is carved with high-precision grid above.The advantage of this measuring system: measuring system does not comprise any magnetic material based on the transformer working principle of band magnetic resistance core, is not subjected to electromagnetic effect, hysteresis can not take place, no demagnetization danger; Security level height (IP67), it is strong to resist abominable working environment ability.
The purpose of this utility model is to adopt following technological scheme to realize: the turntable bearing of described band angle measurement system, the packing ring that comprises the turntable bearing, it is characterized in that: the outer peripheral surface of being close to the turntable bearing washer connects steel grid chi by seam or step, distribute on the outer side surface of described steel grid chi and be carved with size scale, with the measuring head of the more than one angular encoder of installing on the corresponding blowout patche end face in the size scale position of steel grid chi, described each measuring head is supported by the cushion block on the blowout patche end face; The signal that its measuring head is measured is connected with signal processor by lead, and its signal processor is connected with computer by lead.
Described steel grid chi adopts stainless steel to make.
Principle of the present utility model and operation are described below:
The utility model is to process step or the seam that steel grid chi is installed on the packing ring of turntable bearing.Angle measurement system comprises two measuring heads, a cushion block and an E-signal processor.Its measuring head is installed on the blowout patche of turntable bearing, by the distance between pad adjustment measuring head and steel grid chi.The signal of its measuring head is handled by signal processor, outputs to the control system of computer.Circular steel grid chi is installed on turntable bearing washer excircle, and steel grid chi is a ring stainless steel band, is carved with high-precision grid above.The advantage of this measuring system: measuring system does not comprise any magnetic material based on the transformer working principle of band magnetic resistance core, is not subjected to electromagnetic effect, hysteresis can not take place, no demagnetization danger; Security level height (IP67), it is strong to resist abominable working environment ability, is widely used.
The comprehensive above technological scheme of being taked realizes the purpose of this utility model.
Compared with prior art, structure of the present utility model is not only reasonable in design, compact structure, neither be subjected to electromagnetic effect, hysteresis can not take place again, no demagnetization danger, and have security level height (IP67), it is strong and use advantages such as very convenient to resist abominable working environment ability.
