Description
Technical Field
The utility model relates to a found mill round pin axle technical field, specifically a modified found mill round pin axle.
Background
The pin shaft is a standard fastener, can be statically and fixedly connected, can also move relative to a connected piece, and is mainly used at the hinged position of two parts to form a hinged connection. The pin shaft is usually locked by a cotter pin, and has reliable work and convenient disassembly.
At present, the cement mill vertical mill pin shaft is mostly made of 40Cr materials, and due to the fact that the cement mill vertical mill pin shaft is high in hardness and large in brittleness, the pin shaft is divided into three sections of different diameters during design, two steps are formed, the pin shaft is easy to break at a thin position, the service life is seriously affected, and inconvenience is brought to use.
SUMMERY OF THE UTILITY MODEL
For solving prior art's is not enough, the utility model provides a modified immediately grinds round pin axle, the utility model discloses an establish the round pin axle into two sections, cancel a step, and then increased mechanical properties, improved the atress ability of round pin axle, reduced round pin axle fracture probability, optimized round pin axle and axle sleeve assembly form simultaneously, further improved the mechanical properties of round pin axle, improved the life of round pin axle, reduced the round pin axle and changed the frequency, reduced use cost.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:
the improved vertical grinding pin shaft comprises a pin shaft, wherein the pin shaft is divided into two sections, the left section is a large end, the right section is a small end, a joint bearing is arranged at the joint of the two sections of the pin shaft, a shaft sleeve is sleeved on the small end of the pin shaft, and one end of the shaft sleeve is in contact fit with the joint bearing.
Furthermore, a threaded hole is formed in the small end of the pin shaft, a bolt is in threaded fit with the shaft sleeve, and the shaft sleeve is connected with the pin shaft through the bolt.
Furthermore, the pin shaft, the knuckle bearing and the shaft sleeve are all made of 40Cr materials, and the height of the curved surface of the knuckle bearing is higher than that of the large end of the pin shaft and that of the shaft sleeve.
Contrast prior art, the beneficial effects of the utility model are that:
the utility model discloses an establish the round pin axle into two sections, cancel a step, and then increased mechanical properties, improved the atress ability of round pin axle, reduced round pin axle fracture probability, optimized round pin axle and axle sleeve assembly form simultaneously, further improved the mechanical properties of round pin axle, improved the life of round pin axle, reduced the round pin axle and changed the frequency, reduced use cost.
Drawings
FIG. 1 is a schematic structural view of the present invention;
reference numerals shown in the drawings: 1. a pin shaft; 2. a knuckle bearing; 3. a shaft sleeve; 4. and (4) bolts.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
As shown in figure 1, a modified founds and grinds round pin axle, including round pin axle 1, round pin axle 1 divide into two sections, and left side section is the main aspects, and right side section is the tip, 1 two sections junctions of round pin axle are equipped with joint bearing 2, 1 tip cover of round pin axle is equipped with axle sleeve 3, 3 one ends of axle sleeve and 2 contact cooperations of joint bearing.
Specifically, a threaded hole is formed in the small end of the pin shaft 1, a bolt 4 is in threaded fit with the shaft sleeve 3, and the shaft sleeve 3 is connected with the pin shaft 1 through the bolt 4. The shaft sleeve 3 is connected with the pin shaft 1 through the bolt 4, so that the installation and the disassembly are convenient, and the physical strength of operators is saved.
Specifically, the pin shaft 1, the knuckle bearing 2 and the shaft sleeve 3 are all made of 40Cr materials, and the height of the curved surface of the knuckle bearing 3 is higher than the height of the large end of the pin shaft 1 and the height of the shaft sleeve 3. The height of the curved surface of the joint bearing 3 is higher than that of the large end of the pin shaft 1 and that of the shaft sleeve 3, so that the joint bearing can bear load and impact force conveniently.
Example (b):
when the device is used, firstly, the joint bearing 2 is arranged at the joint of two sections of the pin shaft 1, the joint bearing 2 is in contact fit with the pin shaft 1, then the shaft sleeve 3 is sleeved, the shaft sleeve 3 is in contact with the joint bearing 2, the shaft sleeve 3 is connected with the pin shaft 1 through the bolt 4, and then the pin shaft is arranged; the utility model discloses an establish the round pin axle into two sections, cancel a step, and then increased mechanical properties, improved the atress ability of round pin axle, reduced round pin axle fracture probability, optimized round pin axle and axle sleeve assembly form simultaneously, further improved the mechanical properties of round pin axle, improved the life of round pin axle, reduced the round pin axle and changed the frequency, reduced use cost.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
