(patent No.: disclose a kind of power reversing device 201120380900.5), it has solved existing power reversing device can not adapt to long problem apart from transferring power to Chinese utility model patent well.The technological scheme of taking: a kind of power reversing device, comprise casing, be vertically set on driving shaft and driven shaft in the casing, on driving shaft and driven shaft, be socketed with respectively intermeshing driving gear and driven gear, it is characterized in that, described driven shaft is positioned at box house, driving shaft reaches the casing outside, at the distolateral supporting base that is provided with of stretching out of driving shaft.
But the shortcoming that the power reversing device of this structure exists is: when device connects with external impetus equipment, be difficult to guarantee the coaxality of driven shaft and external equipment power input shaft, in the situation of loaded work piece, be easy to cause the damage of power reversing device and external impetus equipment like this.
The model utility content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and a kind of power reversing device is provided, and it can keep preferably coaxality when connecting with external equipment, thus reduce trouble.
The technical solution of the utility model is:
A kind of power reversing device, comprise casing, be vertically installed in driving shaft and driven shaft in the casing, be separately installed with intermeshing driving bevel gear and driven bevel pinion on described driving shaft and the driven shaft, it is characterized in that: described casing is provided with the side box body structure in the place, an end of driven shaft, this end of driven shaft is positioned at described side box body structure, side box body structure one end connects with casing, and place, the other end is provided with bearing mounting hole.When external impetus equipment connected with power reversing device, its power input shaft was installed in by selfaligning ball bearing in the bearing mounting hole of side box body structure, can improve coaxality.
As preferably, side box body structure described in the utility model is provided with oil hole.The power input shaft of external equipment and driven shaft are with splined, and oil hole is used for adding lubricant oil, thereby reduce the spline tooth surface wear.
As preferably, the periphery of driving shaft described in the utility model is arranged with axle sleeve, and an end and the casing of axle sleeve link, and the outer end of driving shaft reaches the outside of axle sleeve the other end, the place, two ends of axle sleeve is provided with respectively block bearing, and block bearing is set on the driving shaft.Be provided with axle sleeve, improved the Security in the driving shaft rotation process.
As preferably, block bearing described in the utility model is tapered roller bearing.Tapered roller bearing can improve the stability in the driving shaft working procedure.
As preferably, driving shaft described in the utility model stretch out the distolateral supporting base that is provided with, described supporting base is set on the axle sleeve.Supporting base is used for supporting driving shaft, to guarantee driving shaft rotational stability in the course of the work.
The beneficial effects of the utility model are: because the side box body structure of driven shaft one end is provided with bearing mounting hole, when the power input shaft of external impetus equipment connects with the driven shaft of power reversing device, selfaligning ball bearing is installed in the bearing mounting hole, power input shaft passes selfaligning ball bearing and installs, can keep preferably coaxality like this, thus the reliability and stability when improving loaded work piece.
