Abstract
The utility model relates to a built-in bearing, which comprises an inner ring and an outer ring in which mounting holes are arranged. The outer circumference of the inner ring is provided with a first race and the inner circumference of the outer ring with a second race. The bearing further comprises balls and a ball inlet. The balls are respectively arranged in the first race and the second race. The ball inlet is arranged on the outer circumference of the inner ring. The bottom of the ball inlet is provided with a first gearset. The circumferential width of the ball inlet close to the mounting holes is less than that of the ball inlet away from the mounting holes. The width of one side of the ball inlet is more than that of the other side thereof. The bearing further comprises a patch which closely matches with the ball inlet. The utility model has the advantages of simple structure and convenient operation, thus saving the labor time and improving the operating efficiency.
Description
Technical field
The utility model relates to a kind of insert bearing.
Background technique
The existing insert bearing that is installed on the big blade of loom heald lifting device, drive big blade and loom connecting rod mechanism movement by the loom conjugate cam, such bearing generally includes inner ring, the outer ring, ball, and the retainer with ball hole, ball is placed in the ball hole, and ball is along rolling in the raceway of inner ring, outer ring formation, in the time of in the raceway that ball is installed into inside and outside circle formation, have certain difficulty, cause the damage bearing easily, shortened the working life of bearing.
The model utility content
At the problems referred to above, the purpose of this utility model provides a kind of simple in structure, insert bearing of being convenient to install.
The technological scheme that realizes the utility model purpose is as follows:
Insert bearing, comprise that the middle part has the inner ring of mounting hole, the outer ring, the excircle of described inner ring is provided with first raceway, the inner circumference of outer ring is provided with second raceway, this bearing also comprises ball, ball-loading hole, described ball is arranged on first raceway, in second raceway, described ball-loading hole is arranged on the excircle of inner ring, the bottom of described ball-loading hole is provided with the first tooth group, the circumferential width of the close mounting hole of described ball-loading hole is less than the circumferential width away from mounting hole, the width of described ball-loading hole one side is greater than the width of opposite side, and this bearing also comprises and the close-fitting abaculus of ball-loading hole.
Further, well cooperate with the second tooth group in order to make the first tooth group, described abaculus is provided with the second tooth group with the described first tooth group equal number, and the described first tooth group and the second tooth group cooperatively interact.
One side relative with being provided with the second tooth group on the described abaculus is provided with the 3rd raceway, and when abaculus was placed in the ball-loading hole, described the 3rd raceway and first raceway were in full accord.
The described first tooth group is the ball-loading hole bottom that is axially disposed within inner ring, the first tooth group can also be arranged on the two side of ball-loading hole, and perhaps the two side of ball-loading hole and bottom are provided with simultaneously.
Adopt above-mentioned described scheme, when abaculus is placed in the ball-loading hole, because the circumferential width of the close mounting hole of ball-loading hole is less than the circumferential width away from mounting hole, the width of described ball-loading hole one side is greater than the width of opposite side, the shape of described ball-loading hole such as chock shape, abaculus and ball-loading hole closely cooperate, and the 3rd raceway and first raceway on the inner ring excircle on the abaculus are in full accord., abaculus is taken off from inner ring during ball at dress, a plurality of balls of needs are embedded from ball-loading hole and enter in the raceway of first raceway and the formation of second raceway, again abaculus is embedded ball-loading hole, so just finished the assembling work of bearing.Therefore the utility model is simple in structure, easy to operate, can save working time, increases work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1 is inner ring, and 2 is mounting hole, and 3 is the outer ring, and 4 is first raceway, and 5 is second raceway, and 6 is the 3rd raceway, and 7 is ball, and 8 is the first tooth group, and 9 is the second tooth group, and 10 is ball-loading hole, and 11 is abaculus.
Embodiment
