Abstract
The utility model discloses a pivoting support driving device, comprising a pivoting support, a worm, a housing, an end cover and a drive motor; the main characteristics of the driving device are that: the inner ring of the pivoting support is connected with the housing in a semi-surrounding way, the worm is arranged in a cylinder body of the housing, the worm is meshed with the outer ring of the pivoting support, the two ends of the worm are axially located by a conical roller bearing, the worm is connected with the drive motor, and the two ends of the housing are sealed and fixed by the end cover. The device has simple structure, low cost and stable and reliable operation, and be applied to a solar power device, a rotational excavator bucket device of an excavator, an aerial working platform device and other rotational driving devices.
Description
Technical field
The utility model relates to a kind of pivoting support drive unit, the secondary pivoting support drive unit of especially a kind of worm and helical gear.It is applicable to other rotating equipment such as rotation bucket device, aerial working platform vehicle device of device of solar generating, excavator.
Technical background
Gear box device, the rotation bucket device of excavator, aerial working platform vehicle device at China's solar electrical energy generation uses rotary supporting device more at present, these devices mostly are to control with the worm and worm gear assistant drive device, the difficulty of processing of considering worm gear is big, cost is high and the flank of tooth of worm gear can't grinding, can't reach higher required precision etc., therefore can replace with the worm and helical gear pair as the not high transmission of this generic request transmission efficiency.Because it is quick and easy many that the relative worm gear of helical gear processing is wanted, the efficient of processing is also higher, and helical gear can carry out grinding to the flank of tooth, can improve the precision and the hardness of the flank of tooth, so it is more than what select worm-gears for use and calculate to select the worm and helical gear pair for use.
Summary of the invention
The technical problems to be solved in the utility model is: pass through when transmission with the secondary worm-gears that replaces of involute profile worm and helical gear, provide a kind of worm and helical gear secondary pivoting support drive unit, thereby reduce production costs to greatest extent, improve the precision of product and the hardness of gear ring.
The technological scheme that the utility model adopted is: this pivoting support drive unit comprises pivoting support, worm screw, case, end cap, drive motor, its main feature is that the pivoting support inner ring adopts the semi-surrounding formula to be connected with case, worm screw is located in the case cylindrical shell, worm screw and pivoting support outer ring are connected with a joggle, axially locating is carried out with tapered roller bearing in the worm screw two ends, worm screw is connected with drive motor, and the two ends of case are fixed with end bracket enclosed.
According to Principles of Gear Connection worm screw is designed to involute profile, allows the normal module of worm screw equate with helical gear normal module, the worm screw angle of lead is consistent with the equal and opposite in direction and the rotation direction of oblique gear spiral angle.
Tapered roller bearing is inserted in worm screw, and matches with step place, case two ends, and the two ends of case are fixed with end bracket enclosed.
The utility model is to utilize the worm and worm gear theory of engagement, and its structure is designed to worm screw and helical gear engagement, drives workpiece work indirectly thereby make drive motor 10 promote worm screw 3 rotations.It had both reduced cost of production, had improved work efficiency again, had improved the precision and the hardness of pivoting support gear ring again.Adapt to multiple rotating machinery.Its project organization compactness has rationally been utilized the space, and is easy to maintenance, can install to connect various drive motors, and be a kind of driving mechanism of simplification.
