It is successively inside plug 4, internal screw thread counterbore 13, grease cup 3, axial oil duct 11.Since the screw thread of installation grease cup 3 is usually thin
Tooth, and the screw thread for installing pin pulling equipment is usually coarse thread, and the nominal diameter for installing pin pulling equipment screw thread is generally large, therefore,
The screw thread of installation grease cup 3 cannot be borrowed to install pin pulling equipment, in addition, to prevent grease cup 3 from blocking, 3 outer end one of grease cup
As lubricating cup sheath is installed.The hinging pin shaft the pin body 1 axially outermost setting internal screw thread counterbore 13, and use
Plug 4 covers internal screw thread counterbore 13, had not only facilitated and has dismantled pin shaft using pin pulling equipment, but also can prevent the corrosion of internal screw thread counterbore 13,
Grease cup 3 is protected, is not required to that lubricating cup sheath is additionally installed again.When dismantling pin shaft, lower end cap 4, grease cup 3 only need to be unloaded, can be used
Pin pulling equipment dismantles pin shaft.When routine servicing, lower end cap 4 only need to be unloaded, butter, lubricating pin shaft, thus effectively will be interior can be supplemented
Screw-threaded counterbore 13 matches with oil duct lubrication.
Embodiment two, as shown in Fig. 1, Fig. 3, Fig. 5, a kind of hinging pin shaft, including pin body 1, otic placode 2,3 and of grease cup
Plug 4；The pin body 1 includes axial oil duct 11 and radial direction oil 12, and the otic placode 2 includes connecting hole 21, location hole 23
With additional threaded bores 22；The pin body 1 passes through connecting hole 21, and integrally welded with otic placode 2；23 fixation of location hole
In the locating piece 5 of pin shaft installation site；The additional threaded bores 22 are symmetrically set in centered on the central axis of the connecting hole 21
Its two sides；The grease cup 3 is assemblied in the end of axial oil duct 11；The plug 4 is assemblied in the additional threaded bores 23, and hides
Cover the additional threaded bores 23.It is not very universal, and price is not low, takes sometimes though pin pulling equipment is conducive to dismantle pin shaft
Band, it is inconvenient for use.The hinging pin shaft on the otic placode 2 be equipped with additional threaded bores 22, dismantle pin shaft when, only need to using with it is auxiliary
The bolt that helps threaded hole 22 to match has corresponding externally threaded element, it is symmetrical it is axial tighten, pin shaft can be extracted outward.
The additional threaded bores 22 are covered using plug 4, the corrosion of additional threaded bores 22 is can effectively prevent, does not influence appearance.
Embodiment three, as shown in figure 1, figure 2, figure 3 and figure 6, a kind of hinging pin shaft, including pin body 1, otic placode 2, butter
Cup 3 and plug 4；The pin body 1 includes that axial oil duct 11, radial direction oil 12 and internal screw thread counterbore 13, the otic placode 2 include
Connecting hole 21, location hole 23 and additional threaded bores 22；The pin body 1 passes through connecting hole 21, and is welded into one with otic placode 2
Body；23 fixation of location hole is in the locating piece 5 of pin shaft installation site；The additional threaded bores 22 are in the connecting hole 21
Centered on mandrel, it is symmetrically set in its two sides；The internal screw thread counterbore 13 is consistent with the specification of the additional threaded bores 22；The Huang
Lubricating cup 3 is assemblied in the end of axial oil duct 11；The internal screw thread counterbore 13 is set to axially outermost, the institute of the pin body 1
It states 13 bottom of internal screw thread counterbore to communicate with the axial oil duct 11, the grease cup 3 is installed on 13 bottom of internal screw thread counterbore, described
Internal screw thread counterbore 13 pushes up the outer diameter that diameter is greater than the grease cup 3.The plug 4 is assemblied in the internal screw thread counterbore 13 and auxiliary spiral shell
Pit 22, and cover the internal screw thread counterbore 13 and additional threaded bores 22.The hinging pin shaft it is axially outermost inside successively
It is plug 4, internal screw thread counterbore 13, grease cup 3, axial oil duct 11.Since the screw thread of installation grease cup 3 is usually closely-pitched, and pacify
The screw thread for filling pin pulling equipment is usually coarse thread, and the nominal diameter for installing pin pulling equipment screw thread is generally large, it is thus impossible to borrow
The screw thread of grease cup 3 is installed to install pin pulling equipment, in addition, 3 outer end of grease cup is generally fitted with to prevent grease cup 3 from blocking
Lubricating cup sheath.If having pin pulling equipment when disassembly, lower end cap 4, grease cup 3 only need to be unloaded, pin shaft can be dismantled using pin pulling equipment.
It, only need to be using to the bolt that additional threaded bores 22 match or with corresponding externally threaded member if not having pin pulling equipment when disassembly
Part, symmetrical axially to tighten, pin shaft can be extracted outward.In addition, pin pulling equipment can also be used, match with additional threaded bores 22
Bolt or have corresponding externally threaded co-operation by dismounting hinge pin.When routine servicing, lower end cap 4 only need to be unloaded, can be supplemented
Butter, lubricating pin shaft.The internal screw thread counterbore 13 and additional threaded bores 22 are covered using plug 4, can effectively prevent the interior spiral shell
The corrosion of line counterbore 13 and additional threaded bores 22 does not influence appearance, and is not required to additionally install lubricating cup sheath again.Due to the interior spiral shell
Line counterbore 13 is consistent with the specification of the additional threaded bores 22, has not only facilitated processing, but also improve the interchangeability of plug 4.
Although be described in detail above to the utility model in conjunction with the embodiments, the technology people of the technical field
Member it is understood that without departing from the purpose of the present invention, can also above-described embodiment be changed or be changed,
It still falls within the protection scope of the present utility model.
