Abstract
The invention provides a pin shaft connecting assembly used for a bucket tooth. The pin shaft connecting assembly comprises the bucket tooth and a pin shaft. A strengthening part is arranged at one end of the bucket tooth. A nut is arranged on the strengthening part. The strengthening part is fixedly connected with the bucket tooth through the nut. A pin shaft seat is arranged at the other end of the bucket tooth. A pin shaft hole is formed in the bucket tooth. The pin shaft penetrates to the pin shaft seat from the pin shaft hole. The pin shaft seat sequentially comprises a round hole, a first conical ring hole, a second conical ring hole and an extending end from right to left. A large threaded section is arranged between the first conical ring hole and the second conical ring hole. The extending end is inserted in the pin shaft hole. The purpose that the pin shaft connecting assembly for the bucket tooth is good in fixation and not likely to disengage will be achieved.
Description
Technical field
The present invention relates to excavator part field, especially relate to a kind of pinned connection assembly for bucket tooth.
Background technology

Summary of the invention
It is good that the problem to be solved in the present invention is to provide a kind of stationarity, the pinned connection assembly for bucket tooth of difficult drop-off.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of pinned connection assembly for bucket tooth, comprise bucket tooth and bearing pin, one end of described bucket tooth is provided with reinforcement, described reinforcement is provided with nut, and described reinforcement is fixedly connected with described bucket tooth by described nut, and the other end of described bucket tooth is provided with axis pin base, described bucket tooth has pin shaft hole, and described bearing pin is through to described axis pin base via described pin shaft hole;
Described axis pin base comprises circular hole, conical ring hole one, conical ring hole two and external part from right to left successively, and be provided with major thread section between described conical ring hole one and described conical ring hole, described external part inserts in described pin shaft hole.
Further, described bearing pin is provided with protective cover in the part of described pin shaft hole, and the material of described protective cover is rubber.
Further, the internal diameter of described protective cover is identical with the diameter of described bearing pin, and the external diameter of described protective cover (7) is identical with the diameter of described pin shaft hole.
Further, described bearing pin is set to " L " type.
Further, be provided with baffle plate between the front end of described bearing pin and described circular hole, and by described nut, described baffle plate be fixedly connected with described circular hole.
Further, on described bearing pin, corresponding described major thread section part is provided with minor thread section, and minor thread section described in described major thread Duan Yu can be completely closed by rotation.
Further, the diameter of described external part is identical with the diameter of described pin-and-hole.
The advantage that the present invention has and beneficial effect are:
(1) the present invention is by adopting the combining form of bearing pin and axis pin base, and bearing pin is " L " type, can make between toothholder and crown effectively fixing, and easily dismantle.
(2) part that described bearing pin is fixed on pin shaft hole is provided with protective cover, and is quality of rubber materials, adds the friction between the inner and bearing pin of pin shaft hole, prevents the phenomenon that bearing pin comes off because of high vibration.
(3) setting of described reinforcement and baffle plate also strengthens the fixation of bucket tooth.
