Detailed description of the invention
Preferred implementation
As it is shown in figure 1, a kind of spiral bevel gear 14 ball screw elevator, including casing 9, casing 9 being rotatably mounted with power input shaft 1, the first end of power input shaft 1 stretches out the outside of casing 9, and the second end of power input shaft 1 is positioned at casing 9；Second end is fixedly connected with spiral bevel gear 14；The ball-screw nut 11 coordinated with spiral bevel gear 14 it is rotatably mounted with in casing 9；The ball-screw 7 coordinated with ball-screw nut 11 it is rotatably mounted with in casing 9.
During use, power input shaft 1 is in transmission connection with actuating unit by drive system, thus by the rotation rotating drive spiral bevel gear 14 of power input shaft 1, thus drive the rotation of ball-screw nut 11, so that ball-screw 7 has axial displacement while rotating, complete lifting action with this.
The speed using spiral bevel gear 14 transmission that ball-screw 7 is rotated on produced axis is fast, by the setting of gear ratio, the rising or falling speed (speed on axis) of ball-screw 7 can reach more than 5000mm/min, and common Worm gear feed screw elevator is typically smaller than 2000/min.
This utility model also includes the first taper roll bearing 5 that bearing block 4 and outer ring are arranged on bearing block 4, and casing 9 is provided with the first opening, and bearing block 4 is fixed on the first opening, and the inner ring of power input shaft 1 is fixed on the inner ring of the first taper roll bearing.
Power input shaft 1 is arranged on bearing block 4 by the first taper roll bearing 5, bearing block 4 is fixed on the first opening, make power input shaft 1 through after bearing block 4 in the first opening stretches into casing 9, thus engage with the ball-screw nut 11 in casing 9, bearing block 4 designs with casing 9 split, reduce the size of part, convenient processing and assembling.
Be provided with between power input shaft 1 and bearing block 4 oil sealing 2 and and cap 3, and cap 3 and oil sealing 2 set gradually along the direction away from the first taper roll bearing 5.And cap 3 is also locking nut, by also cap 3, first taper roll bearing 5 is locked on bearing block 4, owing to needing lubricant environment when the first taper roll bearing 5 works, therefore the outside of also cap 3, oil sealing 2 is installed, thus sealed by the first taper roll bearing 5, thus ensure its lubricant effect.
It is respectively equipped with the second opening and the 3rd opening in two opposing sidewalls of casing 9, the second taper roll bearing 8 and the 3rd taper roll bearing 12 it is separately installed with on second opening and the 3rd opening, one end of described ball-screw 7 is installed in rotation on described second opening by described second taper roll bearing 8, the other end of described ball-screw 7 is by described 3rd taper roll bearing 12 rotationally with on described 3rd opening, and described ball-screw nut 11 is fixed on described 3rd taper roll bearing 12.Second opening, the 3rd opening are set, facilitate the assembling of ball-screw 7, by installing the second taper roll bearing 8 on the second opening, installing the 3rd taper roll bearing 12 on the 3rd opening, to bear axial load and radial load, it is ensured that the steady and longer service life of operation.
Second opening upper cover 6 closes has upper cover 6, the middle part of upper cover 6 to have the through hole passed for ball-screw 7, and the 3rd opening upper cover 6 closes has lower cover 13, the middle part of lower cover 13 to have the through hole passed for ball-screw 7.Casing 9, upper cover 6 plate, lower cover 13 plate design for split, facilitate the assembling of ball-screw 7.
Requirement for height due to lifting, the length of ball-screw 7 is the longest, and when being processed longer axle, difficulty is high, the bad control of cylindricity, another cost is the highest, therefore, ball-screw 7 is arranged to Split type structure, is respectively upper ball-screw 71 and lower ball-screw 72, the two is connected by adapter 10, adapter 10 is between the second taper roll bearing 8 and the 3rd taper roll bearing 12, and upper ball-screw 71 is arranged on the second opening, and lower ball-screw 72 is arranged on the 3rd opening.It addition, ball-screw 7 is arranged to Split type structure, alleviate weight, facilitate assembling.
