DOUBLE-INSULATED MOTOR AND PINION DEVICE

Abstract

A double-insulated motor and pinion device including a motor, motor-fixing seat, pinion, pinion sleeve and double insulation sleeve. The motor and motor-fixing seat are connected together to form a motor assembly. The pinion is mounted on a motor shaft. The pinion sleeve is mounted under the pinion, and the double insulation sleeve is connected under the pinion sleeve. The pinion, pinion sleeve, and double insulation sleeve are mounted together to form a pinion assembly. The pinion assembly is mounted on the motor assembly. It can solve the requirement of basic insulation and reinforced insulation of a series of high voltage direct current products by adding two insulation parts, while reducing space and lowering cost.

DETAILED DESCRIPTION

[0016] The technical solution provided by the embodiments of the double-insulated motor and pinion device of the present application will be described clearly and completely below. It is apparent that the described embodiments are only some embodiments of the double-insulated motor and pinion device, and not all of the embodiments. All other embodiments obtained by an ordinary technical person skilled in the art, without making any creative effort, are within the scope of protection of the double-insulated motor and pinion device of the present application.

[0017] Referring to FIGS. 1 and 2, an embodiment of the double-insulated motor and pinion device may include a motor 7, a motor-fixing seat 6, a pinion 1, a pinion sleeve 2, a double insulation sleeve 3, a motor shaft flywheel 4, and a bearing 5. The motor 7 and the motor-fixing seat 6 can be mounted and connected together to form a motor assembly.

[0018] The pinion 1 may be mounted on a motor shaft. The pinion sleeve 2 may be mounted under the pinion 1. The double insulation sleeve 3 may be connected under the pinion sleeve 2. The pinion 1, the pinion sleeve 2, and the double insulation sleeve 3 may be mounted together to form a pinion assembly. The pinion assembly may be mounted on the motor assembly.

[0019] The motor shaft flywheel 4 can be mounted on the pinion assembly, and the bearing 5 can be mounted on the motor assembly. Hence, the pinion assembly can be fixedly mounted on the motor assembly by means of the motor shaft flywheel 4 and the bearing 5.

[0020] In motor assembly, the motor-fixing seat 6 can be an insulation type motor-fixing seat. It may be made of a plastic piece or a similar insulation piece.

[0021] In the pinion assembly, the double insulation sleeve 3 can be a plastic double insulation sleeve, which may also be made of a plastic piece or a similar insulation piece.

[0022] In the present embodiment, those insulation parts can be made a plastic piece or a similar insulation piece. This can reduce the manufacturing cost.

[0023] The motor-fixing seat 6 and the double insulation sleeve 3 can both be made of an insulation material. This can ensure both basic insulation and reinforced insulation of the entire motor and pinion device. At the same time, it can also be used in a series of high voltage direct current products such as electric direct current garden tools.

[0024] The beneficial effect of the double-insulated an device of the present application is that, through the addition of insulation parts, it can solve the requirement of basic insulation and reinforced insulation of a series of high voltage direct current products, while reducing space and lowering cost.

[0025] The above-mentioned embodiments are merely some embodiments of the double-insulated motor and pinion device of the present application, and the scope of patent protection is not limited to these embodiments. Any equivalent structures or equivalent changes in process using the contents of the present patent specification, or any direct/indirect application in other related field of technology are within the scope of patent protection of the present application.
