Although existing installing hole processing mode disclosure satisfy that use requirement to a certain extent; but; because axle bed distance processes the distant of hole place side; boring bar stretches out long; vibrations often occur during Boring; and then leading to that the size in hole and circularity over tolerance are serious, percent defective is higher and working (machining) efficiency is low.
Content of the invention
In view of this, it is an object of the invention to provide a kind of bevel gear hard-tooth surface speed reducer casing, using the bevel gear hard-tooth surface speed reducer of this casing, machining accuracy and the working (machining) efficiency of installing hole can be effectively improved.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
A kind of bevel gear hard-tooth surface speed reducer casing, including box-like body, the side side wall of described box-like body is provided with connecting hole, it is provided with axle bed in described box-like body, described axle bed is arranged near described connecting hole place side, and in described axle bed, it is provided with the installing hole of axis and described connecting hole diameter parallel, described connecting hole is provided with gap near the side of described axle bed, parallel on the described view installing axially bored line, described installing hole is centrally located in described gap, and the side wall of described gap is more than the radius of boring bar apart from the described minimum range installing axially bored line.
The beneficial effects of the present invention is：
The bevel gear hard-tooth surface speed reducer casing of the present invention, by gap is arranged on connecting hole, and the minimum range of gap distance installation axially bored line is set greater than the radius equal to boring bar, so, in processing mounting holes, boring cutter can stretch into from connection hole, make the extension elongation of boring bar shorter, the vibrations producing during processing are less, that is, the precision processing the installing hole obtaining is higher, and working (machining) efficiency is also higher.

Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in figure 5, being the structural representation of the bevel gear hard-tooth surface speed reducer using the present embodiment casing.This bevel gear hard-tooth surface speed reducer, including casing 1, the casing 1 of the present embodiment includes box-like body 2, the side side wall of box-like body is provided with connecting hole 3, it is provided with axle bed 4 in box-like body 2, axle bed 4 is arranged near connecting hole 3 place side, and is provided with the installing hole 5 of axis and connecting hole 3 diameter parallel in axle bed 4.Connecting hole 3 is provided with gap 6 near the side of axle bed 4, and on the view parallel to installing hole 5 axis, installing hole 5 is centrally located in gap 6, and the side wall of gap 6 apart from installing hole 5 axis minimum range be more than boring bar 7 radius.On connecting hole 3, input module is installed, input module includes input flange 8 and the input shaft 9 being sleeved in input flange 8, it is respectively equipped with input end bearing 10 between the two ends of input flange 8 and input shaft 9, installing hole 5 inner sleeve installs sprocket drive spindle 11, is respectively equipped with intermeshing gear wheel 12 and little gear 13 between gear shaft 11 and input shaft 9.
The bevel gear hard-tooth surface speed reducer casing of the present embodiment, by gap is arranged on connecting hole, and the minimum range of gap distance installation axially bored line is set greater than the radius equal to boring bar, so, in processing mounting holes, boring cutter can stretch into from connection hole, make the extension elongation of boring bar shorter, the vibrations producing during processing are less, that is, the precision processing the installing hole obtaining is higher, and working (machining) efficiency is also higher.
Input flange 8 includes flange body, the reductor end flanges 14 being respectively arranged at two ends with for being connected of flange body and the power end flanges 15 for being connected with power set with connecting hole.Input shaft 9 includes inputting shaft body, input shaft body includes the deferent segment 16 for being set with little gear 13 and the input section 17 for being connected with the output shaft of power set, deferent segment 16 is provided with keyway 18, it is provided with connection blind hole 19 in input section 17, connect and in blind hole 19, be provided with keyway or spline, the bottom connecting blind hole 19 is arranged near deferent segment.The flange body of the present embodiment is provided with the screw 20 between two input end bearings 10.
