Abstract

The invention relates to a single-side dual-drive accurate positioning transmission device. The single-side dual-drive accurate positioning transmission device comprises a base (1); a rotating gear (2) is arranged in the base (1) through a bearing; a first gear ring (3) and a second gear ring (4) are arranged on the rotating gear (2) in a left and right parallel manner; a first worm (5) and a second worm (6) are arranged below the rotating gear (2) in a left and right parallel manner; the first worm (5) and the second worm (6) are engaged with the first gear ring (3) and the second gear ring (4) correspondingly; and a first motor (7) and a second motor (8) are arranged on the outer side of the base (1), and drive the first worm (5) and the second worm (6) correspondingly. The single-side dual-drive accurate positioning transmission device can eliminate a gap to perform accurate positioning and improve the tracing precision on the premise that the machining precision and the machining cost of a worm gear and worm are not improved.

Description

technical field

[0001] The invention relates to a single-side double-drive precise positioning transmission device, which is widely used in various transmission mechanisms, especially the transmission mechanism of a solar thermal power generation tracking system. Background technique

[0002] At present, in the pitch angle transmission of the tracking system of solar thermal power generation, a large number of single worm drive reducers with slewing support structure are used. The advantages are large transmission ratio, stable transmission, self-locking, and can withstand axial force and radial force. and tipping moment. The disadvantages are: 1. No matter how high the precision of the worm gear is, there will be an meshing gap, otherwise it will be stuck and unable to rotate. Moreover, if the precision is too high, the processing cost will be very high, so the solar lens is easy to shake due to the meshing gap, which affects power generation. Efficiency; 2. In the pitchin...

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1~Figure 3 As shown, a single-side double-drive precise positioning transmission device in this embodiment includes a base 1, and a rotary gear 2 is arranged in the base 1 through a bearing, and the left and right parallel gears are arranged on the rotary gear 2. A ring gear 3 and a second ring gear 4, a first worm 5 and a second worm 6 are arranged parallel to the left and right below the rotary gear 2, and the first worm 5 and the second worm 6 are respectively connected with the first ring gear 3 and the second worm 6. The second ring gear 4 is engaged, and a first motor 7 and a second motor 8 are arranged on the outside of the base 1, and the first motor 7 and the second motor 8 drive the first worm 5 and the second worm 6 respectively;

[0022] The left and right sides of the rotary gear 2 are planes, and the left and...
