Description

Technical Field

[0001] The utility model relates to a rotary reducer with a worm end feedback outputting a rotation angle, belonging to the technical field of rotary reducers. Background Art

[0002] As the use of large-area photovoltaic tracking systems increases, the number of tracking systems employing slew reduction drives is also increasing. Market requirements for tracking reducers are also becoming increasingly diverse, with requirements for higher load resistance, improved structural reliability, and higher cost-performance.

[0003] Existing solar tracking slewing reducers consist of a housing, gears, a worm, and a drive unit. The drive unit rotates, driving the worm, which in turn drives the gear or gears. Currently, there are two main methods for controlling the angle tracking at the output of a slewing reducer:

[0004] 1. Install an encoder on the worm end. This type of structure requires a high encoder, a complex control system, and a high overall cost.

[0005] 2. Install a fixed-angle tracking sensor on the output end. The sensor rotates with the rotary reducer and provides feedback when the reducer reaches a fixed angle limit. This tracking method only provides feedback when the rotary reducer reaches a fixed angle and cannot track the device's rotation angle in real time. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a rotary reducer with a worm end feedback output rotation angle in view of the above-mentioned prior art, which has a simple structure, greatly reduces the installation cost, and can track the rotation angle of the device in real time.

[0007] The technical solution adopted by the present invention to solve the above-mentioned problem is: a rotary reducer with a worm end feedback output rotation angle, which includes a base, the base includes a seat ring and a shaft housing, a gear is arranged in the seat ring, a worm is arranged in the shaft housing, the gear and the worm are matched, a reduction box and a motor are respectively arranged on the left and right sides of the shaft housing, the left and right ends of the worm are respectively connected to the reduction box and the motor, and the output end of the reduction box is connected to an angle sensor.

[0008] Optionally, the reduction ratio of the reduction box is the same as the reduction ratio between the gear and the worm.

[0009] Optionally, the reduction ratio of the reduction box is different from the reduction ratio of the gear and the worm.

[0010] Optionally, the angle sensor is arranged at the outer end of the reduction gearbox.

[0011] Optionally, the output end of the reduction gearbox and the angle sensor are fixed in a separate connection.

[0012] Optionally, the output end of the reduction gearbox and the angle sensor are fixed integrally.

[0013] Optionally, the gear is in the form of a worm gear.

[0014] Optionally, a protective cover is provided outside the angle sensor.

[0015] Optionally, the protective cover is connected to the reduction gearbox via bolts.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The worm end of the utility model is connected to the reduction box, and the output end of the reduction box is connected to the angle sensor, thereby realizing output end angle tracking. This can solve the problem of the existing technology of adding an encoder to the worm end, the high cost of the rotary device angle tracking component and the system installation cost;

[0018] 2. The worm end of the utility model is connected to the reduction box, and the output end of the reduction box is connected to the angle sensor, thereby realizing output end angle tracking, which can solve the problem of the inability to provide real-time angle feedback during the angle tracking operation of the drive rotary device in the prior art.

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 3 As shown, in this embodiment, a rotary reducer with worm-end feedback output rotation angle comprises a base 1, the base 1 comprising a seat ring 1.1 and a shaft housing 1.2, a gear 2 being provided in the seat ring 1.1, a worm 3 being provided in the shaft housing 1.2, the gear 2 and the worm 3 being matched, a reduction box 4 and a motor 5 being provided on the left and right sides of the shaft housing 1.2, the left and right ends of the worm 3 being connected to the reduction box 4 and the motor 5, respectively, and an angle sensor 6 being provided on the output end of the reduction box 4;

[0034] The reduction ratio of the reduction box 4 is the same as the reduction ratio between the gear 2 and the worm 3;

[0035] The angle sensor 6 is arranged at the outer end of the reduction box 4;

[0036] The output end of the reduction gearbox 4 and the angle sensor 6 can be connected and fixed separately or fixed as one body, which saves costs.

[0037] The gear 2 may also be in the form of a worm gear;

[0038] The reduction ratio of the reduction box 4 may also be different from the reduction ratio of the worm gear, and the output angle can be obtained by conversion;

[0039] A protective cover 7 is provided outside the angle sensor 6;

[0040] The protective cover 7 is connected to the reduction box 4 by bolts.

[0041] Working principle:

[0042] The drive motor rotates the worm, which meshes with the gear to achieve gear rotation. The worm is also connected to the reduction gearbox, which in turn drives the reduction gearbox's rotation. The reduction gearbox's output is connected to an angle sensor, which displays the reduction gearbox's output angle in real time. The reduction ratio of the reduction gearbox is the same as the ratio between the gear and the worm, so the rotation angle of the reduction gearbox output is the same as the gear's. Therefore, the rotation angle displayed by the angle sensor is the same as the gear's rotation angle, enabling real-time gear angle tracking.

[0043] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
