Abstract
The utility model discloses a bolt structure for connecting a chain wheel tooth slice and a chain wheel hub, which comprises a bolt body, a bolt hole, a nut, a flat pad and an elastic pad, wherein the inner wall of the bolt hole is in bonding connection with an outer expansion sleeve, an inner expansion sleeve matched with the outer expansion sleeve is arranged in the outer expansion sleeve, and the inner wall of the inner expansion sleeve and the bolt body penetrating in the bolt hole are in bonding connection. Because the structure is adopted, the utility model has the following advantages that: 1. the bolt structure for connecting the chain wheel tooth slice and the chain wheel hub is firmer and not easy to shear due to fatigue; 2. the safety performance and the service life of equipment is respectively improved and prolonged; and 3. the bolt structure has simple structure and good effect.
Description
Technical field
The utility model relates to the sprocket wheel processing technique field, the bolt arrangement of particularly a kind of connection chain wheel gear piece and chain wheel hub.
Background technique
At present, often need use split type sprocket wheel in the industrial production, common split type sprocket wheel comprises sprocket wheel gear piece and chain wheel hub, and the sprocket wheel gear piece directly is connected by bolt arrangement with the joint of chain wheel hub.Bolt arrangement as shown in Figure 2 comprises the body of bolt 1, nut 2 and bolt hole, and it is fixing by nut 2 that the body of bolt 1 passes bolt hole.The place, aperture of bolt hole is provided with plain cushion 3, accompanies bullet pad 4 between plain cushion 3 and the nut 2.Plain cushion 3 and bullet pad 4 play a part auxiliary fixing.Even this body of bolt 1 adopts hard-cover to join with its bolt hole, also is Spielpassung between them, between sprocket wheel gear piece after the carrying and chain wheel hub, can produce shearing force, cause the body of bolt 1 fatigue easily to be cut off, influence device ' and working life.
The model utility content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of bolt arrangement that is difficult for because of fatigue is cut off, the connection chain of long service life is taken turns gear piece and chain wheel hub.
For solving the problems of the technologies described above, the technical solution of the utility model is: the bolt arrangement of a kind of connection chain wheel gear piece and chain wheel hub, comprise the body of bolt, bolt hole, nut, plain cushion and bullet pad, the inwall of described bolt hole has been fitted and connected an outer swelling cover, be provided with an interior swelling cover that matches with it in the outer swelling cover, described in the swelling cover inwall be through at the body of bolt in the bolt hole for being fitted and connected.
The outer wall of swelling cover is butt conical surface shape in described.
The outer wall of swelling cover matches with the inwall of outer swelling cover in described.
The utility model adopts said structure, has the following advantages: make that 1, the bolt arrangement of connection chain wheel gear piece and chain wheel hub is more firm, be difficult for cutting off because of tired; 2, improved device ' and working life; 3, simple in structure, respond well.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of background technique in the utility model;
In Fig. 1～Fig. 2,1, the body of bolt; 2, nut; 3, plain cushion; 4, bullet pad; 5, outer swelling cover; 6, interior swelling cover.
Embodiment
The bolt arrangement of a kind of as shown in Figure 1 connection chain wheel gear piece and chain wheel hub, comprise the body of bolt 1, bolt hole, nut 2, plain cushion 3 and bullet pad 4, the inwall of bolt hole has been fitted and connected an outer swelling cover 5, be provided with an interior swelling cover 6 that matches with it in the outer swelling cover 5, the outer wall of interior swelling cover 6 is butt conical surface shape, the outer wall of interior swelling cover 6 matches with the inwall of outer swelling cover 5, and the inclination of the conical surface makes the outer swelling cover 5 and the interior swelling that match overlap 6 easy swellings.The inwall of interior swelling cover 6 and be through at the body of bolt 1 in the bolt hole for being fitted and connected.During installation, after outer swelling cover 5 that will cooperatively interact earlier and interior swelling cover 6 are put into bolt hole, go up the body of bolt 1 again and it is tightened.Outer swelling cover 5 and the 6 automatic swellings of interior swelling cover make that like this bolt arrangement is more firm, avoid the body of bolt 1 to cut off because of tired, thereby improve device ' and working life.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
Claims (3)
