Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
The first embodiment is as follows:
as shown in fig. 1, 2, 5 and 6, a drive bevel gear convenient to installation, including installation axle 1 and rather than fixed connection's gear body 2, set up on gear body 2 with installation axle 1 complex mounting hole 9, set up the teeth of a cogwheel 10 that a plurality of annular arrays distribute and set up on the periphery wall of gear body 2, inwards cave in on the periphery wall of the teeth of a cogwheel 10 and form oil storage tank 11, the oil storage tank 11 intussuseption is filled with lubricating oil.
The width that the one end of installation axle 1 was kept away from to the external splines is less than its width that is close to the one end of installation axle 1, interval between the adjacent external splines keeps unchangeable after keeping away from installation axle 1 one end and beginning to dwindle gradually, the external splines include key tooth one 4, the length of connecting axle 3 is greater than the length of key tooth one 4, key tooth one 4 cross-section is the arc, and the laminating of the inner wall of key tooth one 4 and 3 periphery walls of connecting axle, its outer wall flushes with installation axle 1 periphery wall, a direction inclined plane 5 has all been seted up to key tooth one 4 one end both sides of keeping away from installation axle 1, form embedding portion 6 between the adjacent key.
Through setting up oil storage tank 11 to make when people utilize this drive bevel gear and driven bevel gear to mesh, the lubricating oil in the oil storage tank 11 can be followed the oil storage tank 11 and flowed out, then enters into between drive bevel gear and the driven bevel gear, makes both can play better lubricated effect when taking place driven, avoids drive bevel gear's the condition that the teeth of a cogwheel 10 takes place wearing and tearing, has prolonged this drive bevel gear's life. And when the drive bevel gear need take place the pivoted through installing other driving medium of axle 1 drive, people can insert connecting axle 3 in the internal spline of driving medium earlier, then along with connecting axle 3 constantly submerges in the driving medium, key tooth 4 enters into between the adjacent internal spline, thereby make the direction inclined plane 5 on the key tooth 4 can play better direction effect to the internal spline, then make under the effect of direction inclined plane 5, make the internal spline enter into between the embedding part 6 between the adjacent key tooth 4, thereby make connecting axle 3 and driving medium can play better connection effect through key tooth 4, and when both take place to connect, can play effectual direction effect through the direction inclined plane 5 of key tooth 4, make things convenient for people to assemble the driving medium.
Example two: as shown in fig. 3-6, unlike the first embodiment,
the external splines include two 7 of key teeth, two 7 of key teeth by fixed connection connecting shaft 3 periphery wall and the three prismatic column portion of installation axle 1 and with connecting shaft 3 periphery wall and three prismatic column portion fixed connection's tetrahedral portion constitute, be equipped with two 8 of direction inclined planes on the tetrahedral portion, the width and the thickness of tetrahedral portion begin to increase gradually from the one end of keeping away from three prismatic column portion, form embedding portion 6 between two 7 of adjacent key teeth, the length of two 7 of key teeth is less than the length of connecting shaft 3.
When the driving bevel gear needs to drive other transmission parts to rotate through the mounting shaft 1, people can firstly insert the connecting shaft 3 into the internal spline of the transmission part, then, as the connecting shaft 3 is continuously immersed into the transmission member, when the tetrahedral body enters between the adjacent internal splines, because the second guide inclined plane 8 is arranged on the four-face part, the second guide inclined plane 8 can play a certain guide effect on the internal spline, and the thickness of the tetrahedral part is gradually increased from one end far away from the triangular prism part, so that as the connecting shaft 3 continuously enters the transmission member, under the guide effect of tetrahedral portion, the internal spline enters into embedding portion 6 between two adjacent key teeth 7 in, then people further promote the driving medium, make the internal spline of driving medium imbed between the adjacent triangular prism portion to make the driving medium can take place the assembled relation with connecting axle 3 comparatively easily.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
