Embodiment 1

[0036] Such as Figure 1-3 Shown, a kind of pin shaft and its connecting structure, it comprises pin shaft body 9, and described pin shaft body 9 passes through first pin shaft connecting piece 13 and second pin shaft connecting piece 12, on both sides of pin shaft body 9 The pin shaft pressing plate 5 for axially limiting the pin shaft body 9 is mounted symmetrically on the end, the pin shaft pressing plate 5 is installed on the fixing plate 6 through the first screw 4, and the outer end surface of the pin shaft pressing plate 5 is provided with Pin shaft fixing nuts 2 are installed at both ends of the pin shaft body 9 . By adopting the above-mentioned pin shaft and its connection structure, it can be used in occasions that bear a large axial force, and the lubricating oil filling device can effectively reduce the gap between the pin shaft body 9 and the second pin shaft connecting piece 12. The friction force between them can be automatically lubricated through the automati...

Embodiment 2

[0046] The assembly method of any one of the described pin shaft and its connecting structure, it comprises the following steps:

[0047] Step1: Install the oil film thickness sensor 15 at the oil groove gap 8 on the pin body 9;

[0048] Step2: Pass the pin body 9 through the first pin connector 13, the limit plate 7 and the second pin connector 12 in sequence;

[0049]Step3: install the pin pressing plate 5 at both ends of the pin body 9, and install the pin pressing plate 5 on the fixing plate 6 through the first screw 4;

[0050] Step4: install the pin shaft fixing nut 2 on the two threaded sections 14 of the pin shaft body 9, and press and fix the pin shaft pressing plate 5 through the pin shaft fixing nut 2;

[0051] Step5: Fix and install the second screw 3 on the outer end surface of the pin fixing nut 2, and fix the pin fixing nut 2 on the outer end surface of the pin pressing plate 5 through the second screw 3;

[0052] Step6: Install the oil nozzle 1 at the axial h...

Abstract

The invention discloses a pin shaft and a connecting structure and an assembling method thereof. The pin shaft comprises a pin shaft body, and the pin shaft body penetrates through a first pin shaft connecting piece and a second pin shaft connecting piece; pin shaft pressing plates used for axially limiting the pin shaft body are symmetrically arranged at the two ends of the pin shaft body, the pin shaft pressing plates are arranged on fixing plates through first screw, and pin shaft fixing screw caps are arranged on the outer end faces of the pin shaft pressing plates; and pin shaft fixing nuts are arranged at the two tail ends of the pin shaft body. Oil groove notches are formed in the position of the pin shaft body and the second pin shaft connecting piece, the pin shaft body and the second pin shaft connecting piece do relative movement and are in contact with each other, and the oil groove notches are connected with a lubricating oil filling device. The pin shaft and the connecting structure thereof are used in heavy equipment and can bear large axial force, the abrasion of the pin shaft is effectively reduced by adopting the lubricating system, and the service life of the pinshaft is prolonged.

Description

technical field [0001] The invention relates to the field of heavy crushing equipment, in particular to a pin shaft and its connecting structure. Background technique [0002] In the heavy-duty crushing equipment, a pin shaft is required, and the pin shaft needs to bear a large axial force. In addition, due to the large radial force, the wear of the pin shaft will be aggravated. Therefore, in order to meet the above-mentioned use requirements, it is necessary Design a new pin shaft for the above occasions. Contents of the invention [0003] The object of the present invention is to provide a pin shaft and its connection structure, which are used in heavy equipment, and can bear a large axial force, and effectively reduce the wear of the pin shaft by using a lubrication system , prolonging its service life. [0004] In order to achieve the above-mentioned technical features, the object of the present invention is achieved in the following way: a pin shaft and its connecti...
