Abstract
The utility model relates to a two-raceway inner ring consisting of a left inner ring and a right inner ring. The inner ring has the innovative points that the inner side surface of the left inner ring is drilled with a left positioning hole; the inner side surface of the right inner ring is drilled with a right positioning hole; the central axes of the left and right positioning holes are the same in position in the axial direction of the left and right inner rings respectively; and a positioning pin is embedded in each of the left and right positioning holes. Through the positioning holes on the left and right inner rings, the left and right inner rings are processed by the same reference after being embedded, so that the high combination accuracy of the left and right inner rings is ensured and the running stability is improved.
Description
Technical field
The utility model relates to a kind of pair of raceway inner ring, particularly a kind of stable double row bearing inner ring.
Background technique
The double row bearing inner ring is made of two independently single raceway inner rings, constitutes a two raceway inner ring in use.Because two independent inner rings process respectively, the machining benchmark difference of employing, even adopt identical machining benchmark, the reference line after its combination is inconsistent, the behavior low precision influences the operation stability of bearing.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of stable double row bearing inner ring.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pair of raceway inner ring, form by left inner ring and right inner ring, its innovative point is: the inner side surface of described left inner ring is drilled with left positioning hole, the inner side surface of right inner ring is drilled with right positioning hole, it is identical that the central axis of described left and right positioning hole is radially gone up the position at the inner ring of part separately, and described left and right positioning hole is embedded with a locating stud.
Advantage of the present utility model is: by the positioning hole on left and right inner ring, process with same benchmark after making left and right inner ring chimeric again, guarantee that both make up the precision height, improve operation stability.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in drawings, the utility model relates to a kind of stable double row bearing inner ring, it is combined by left inner ring 1 and right inner ring 2, the inner side surface of left side inner ring 1 is drilled with left positioning hole 3, the inner side surface of right inner ring 2 is drilled with right positioning hole 4, it is identical that 4 central axis of this left side positioning hole 3, right positioning hole are radially gone up the position at the inner ring of part separately, and left positioning hole 3, right positioning hole 4 are embedded with a locating stud 5.
Claims (1)
1. two raceway inner ring, form by left inner ring and right inner ring, it is characterized in that: the inner side surface of described left inner ring is drilled with left positioning hole, the inner side surface of right inner ring is drilled with right positioning hole, it is identical that the central axis of described left and right positioning hole is radially gone up the position at the inner ring of part separately, and described left and right positioning hole is embedded with a locating stud.
