Abstract
The utility model provides an external raceway measurement device of a double-row taper roller bearing. The utility model mainly comprises a chassis (1), a raceway angle meter (2), a raceway diameter meter (3), a raceway angle measurement fulcrum (4), a raceway diameter measurement fulcrum (5) and a fixing measurement fulcrum (6), wherein, the raceway angle measurement fulcrum (4) is connected to the raceway angle meter (2), the raceway diameter measurement fulcrum (5) is connected to the raceway diameter meter (3), and the top part of the chassis (1) is provided with an annular column (9) which is used for locating the base face of the external raceway of the bearing. The utility model does not change the main structure of the external raceway measurement device of the original taper roller bearing, and the three fulcra are designed to be an annular column. The utility model can cause the fulcrum of a meter to contact the base face of the outer ring of the bearing, control the measurement error of taper angle deviation and radial pulsation within 1 micron, the play fit rate of the finished product bearing basically achieves 100%, and the measurement of a product line batch is greatly convenient.
Description
Affiliated technical field
The utility model belongs to a kind of raceway measurement mechanism, relates generally to the outer raceway measuring instrument of a kind of double-row conical bearing.
Background technology
At present, domestic bearing industry carries out on the raceway surveying instrument outside original taper roll bearing basically to the measurement of the outer raceway of double-row conical bearing, as shown in Figure 1, it mainly is made of base 1, raceway angles instrument 2, raceway diameter instrument 3, raceway angles measurement fulcrum 4, raceway diameter measurement fulcrum 5, fixation measuring fulcrum 6, end face fulcrum 7 etc., measures fulcrum and by lever principle measured piece (8) change in size is delivered to instrument.The location of itself and bearing outer ring reference field is that three fulcrums by base 1 position, contact between the two is the some contact, this makes the coning angle deviation of outer ring raceway and a raceway very big to the measuring error of the diameter run-out of another raceway, about 5 μ m, the play trap rate of finished product is between 30%-50%, and efficient is low, the detection in batches of incompatibility production line.
Summary of the invention
The purpose of this utility model provides the outer raceway measuring instrument of a kind of double-row conical bearing, and it can be controlled at measuring error and repeatable accuracy in the requirement of the play that guarantees bearing completed products and running accuracy.
The purpose of this utility model can adopt following technical scheme to realize: it mainly mainly is made of base, raceway angles instrument, raceway diameter instrument, raceway angles measurement fulcrum, raceway diameter measurement fulcrum, fixation measuring fulcrum it, is provided with one on base top and is used for the circular cylinder that the bearing outer ring reference field is located.
From the above mentioned, the utility model does not change the primary structure of the outer raceway surveying instrument of original taper roll bearing, three fulcrums on it are arranged to a circular cylinder, it can make the instrument fulcrum contact with the locating surface of bearing outer ring reference field, the measuring error of coning angle deviation and diameter run-out is controlled in the 1 μ m, the play trap rate of finished product bearing reaches 100% basically, greatly facilitates production line detection in batches.
