Detailed description of the invention
The present invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
With reference to shown in Fig. 2, the present invention provide a kind of can the gear coupling of rapid disassembling, the left side external tooth cover 1 equal including external diameter and right side external tooth cover 7, internal tooth casing 4 and location sealing set 6.The internal diameter of left side external tooth cover 1 and right side external tooth cover 7 is the most equal, it is ensured that the present invention may be used for two rotating shafts that connecting external diameter is equal or different.The internal diameter that the present embodiment uses left side external tooth cover 1 and right side external tooth cover 7 is equal.The inwall of left side external tooth cover 1 and right side external tooth cover 7 connects by the end of spline and two rotating shafts to be connected is fixing respectively.Internal tooth casing 4 is enclosed within left side external tooth cover 1 and right side external tooth cover 7 junction, and is connected by gear pair with left side external tooth cover 1 and right side external tooth cover 7, and the generally external tooth of left side external tooth cover and right side external tooth cover is processed into barreled tooth flank, can compensate the relative skew of two transmission axis.Left side, coordinating between right side external tooth cover 1,7 and rotating shaft to be connected use spline, and not only intensity is high, it is possible to be used for transmitting high-power, high pulling torque, and processing cost is low.The axial two ends of internal tooth casing 4 are fixed with location sealing set 6 by bolt 2 respectively, and location sealing set 6 is split type structure, is symmetricly set on axis both sides.Location sealing set 6 one aspects can fix internal tooth casing 4, on the other hand foreign material can be stoped to enter the space between internal tooth casing 4 and left side, right side external tooth cover 1,7, reduce internal tooth casing 4 and left side, the abrasion of right side external tooth cover 1,7 coupling part, improve torque transfer efficiency, increase the service life.
When disassembling, it is only necessary to unclamp the bolt on location sealing set 6, it is not necessary to mobile or rotating machinery, the sharp separation of two rotating shafts can be realized.Carrying out the connection between internal tooth casing 4 compared to tradition gear coupling by bolt 10, when transmitting same torque, its structure of connected mode of the present invention, size, weight are respectively less than tradition gear coupling, are particularly well-suited to ore deposit underground work.
Embodiment 2
As in figure 2 it is shown, on the basis of embodiment 1, location sealing set 6 is in hollow semi-cylindrical column, and one end internal diameter is equal to internal tooth casing 4 external diameter, other end internal diameter is equal to left side external tooth cover 1 or the external diameter of the locating slot 13 of right side external tooth cover 7.Dissection type location sealing set 6 is respectively nested in outside internal tooth casing 4 and left side external tooth cover 1 or right side external tooth cover 7 along axis both sides.Dissection type location sealing overlaps 6 one end open, is used for embedding internal tooth casing 4；One end is closed, by with the locating slot 13 phase card of left side external tooth cover 1 or right side external tooth cover 7 and, internal tooth casing 4 opposing left, the moving axially of right side external tooth cover 1,7 can be limited, improve the stability of connection.
Embodiment 3
On this basis, respectively and there is radial clearance with right side external tooth cover 7 in left side external tooth cover 1 between corresponding rotating shaft, prevent rotating shaft thermal expansion or run that the reason such as vibrations causes stuck.Can compensate the radial displacement of rotating shaft, the connection making two rotating shafts is more stable simultaneously.
Embodiment 4
On the basis of above-described embodiment, as in figure 2 it is shown, the axial length of location sealing set 6 is less than the half of internal tooth casing 4 length, the middle part of internal tooth casing 4 outer wall is radially provided with oil-in 3, described oil-in 3 runs through the sidewall of internal tooth casing 4, extends to left side external tooth cover 1 and the contact surface of right side external tooth cover 7.Torque transfer efficiency can be improved by oil-in 3 to left side, be lubricated between right side external tooth cover 1,7 and internal tooth casing 4, reduce abrasion.In the present embodiment, the oil-in 3 on internal tooth casing 4 outer wall is also equipped with oil nozzle, it is simple to the materials such as oil addition.
It addition, in the above-described embodiments, all can be provided with multi-sealed circle 5 between location sealing set 6 and internal tooth casing 4 outer wall, it is ensured that airtight between location sealing set 6 and internal tooth casing 4, prevent external dust, granule from entering, tooth is damaged.
During installation, first left side external tooth cover 1 and right side external tooth cover 7 are respectively embedded into internal tooth casing 4, then two groups of dissection type location sealing sets 6 are enclosed within internal tooth casing 4 two ends, and fix with bolt.
One group of dissection type location sealing set 6 in left side is arranged in the locating slot 13 of left side external tooth cover 1, is blocked by internal tooth casing 4 cylindrical simultaneously, with bolt by fixing for the connection of the one of left side group of dissection type location sealing set 6.In like manner, one group of location sealing set 6 on right side is arranged in the locating slot 13 of right side external tooth cover 7, is blocked by internal tooth casing 4 cylindrical simultaneously, and with bolt by fixing for the connection of the one of right side group of location sealing set 6, left and right order is interchangeable.Finally on oil-in 3, install oil nozzle.
The present invention transmits torque by internal tooth casing 4, the dissection type location sealing set 6 used, and only need to be attached by two bolts, it is not necessary to mobile or rotating machinery, can realize rapid disassembling and separate.Structure, size, weight are respectively less than tradition gear coupling, are particularly well-suited to ore deposit underground work.
