Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The pan-tilt motor and the pan-tilt provided by the embodiments of the present invention are used for aerial photography as auxiliary devices for photographing, photographing, monitoring, and sampling. The platform is used to carry the load to realize the fixation of the load, the adjustment of the posture of the load (for example: changing the height, inclination and / or direction of the load) and the stable maintenance of the load in a determined postu...

Abstract

The invention discloses a pan-tilt motor (10), comprising a rotor component (11), a motor shaft (12) and a stator component (13). The motor shaft (12) comprises a shaft body (122), a first end (124) and a second end (126). The first end (124) if fixedly connected to the rotor component (11). The stator component (13) sleeves the periphery of the shaft body (122) and is connected to the motor shaft (12) in a rotating manner through a pair of bearings (15). The pair of bearings (15) are disposed near the first end (124) and the second end (126). The pan-tilt motor (10) also comprises a compressing piece (16) and an elastic body (18). The compressing piece (16) matches with the second end (126), and thereby the stator component (13) is positioned at the motor shaft (12) in an axial direction. The elastic piece (18) and a bearing pad (152) are both disposed between the compressing piece (16) and the bearing (15) adjacent to the second end (126). The bearing pad (152) clings to the bearing (15). The elastic piece (18) is disposed between the bearing pad (152) and the compressing piece (16). The elastic body (18) is elastically deformed through the compressing piece (16), and thereby the axial pretightening force of the pan-tilt motor (10) can be ensured.

Description

technical field [0001] The invention relates to the technical field of aircraft power devices, in particular to a motor for a pan-tilt. Background technique [0002] In the field of aerial photography gimbals, the gimbal structure is generally designed to be lighter, so the bearings are relatively small. The axial bearing capacity of the bearing is limited, and the preload of the axial clearance becomes one of the key factors affecting the shooting effect of the gimbal. In order to enhance the stability of the gimbal, it is necessary to eliminate the axial clearance between the bearings in the gimbal shaft system and provide a certain preload between the rotor and the stator seat. Most of the existing small pan / tilts adopt the method of cementing the outer ring of the bearing and the fixed part of the stator seat of the motor, and the cementing of the motor shaft and the inner ring of the bearing. At the same time, the preload of the bearing is realized by maintaining the p...
