Description

Technical Field

[0001] The utility model relates to the technical field of stereo garages, in particular to a brushless DC motor with multi-angle conversion for a steering gear. Background Art

[0002] A steering gear is a large piece of deck machinery on a ship. Its size is determined by the exterior outfitting and conforming to classification society specifications. Torque is a key consideration when selecting a steering gear. Currently, most marine steering gears are electro-hydraulic, meaning the hydraulic equipment is remotely controlled by an electric device. There are two types: The reciprocating piston type works by converting high- and low-pressure oil to generate linear motion, which is converted into rotational motion by the tiller. The rotary vane type, on the other hand, uses high- and low-pressure oil directly on the rotor. While compact and efficient, it also comes at a higher cost. Hydraulic steering gears use a hydraulic control cylinder to rotate the steering control plate. Synchronizing rods synchronize the rotation of the two steering shafts, controlling the steering plate's direction. However, using synchronization rods to drive the steering shafts has certain drawbacks: After prolonged use, the synchronization rod and the main shaft connection wear, reducing the connection strength. This can lead to transmission backlash and understeering. Utility Model Content

[0003] The purpose of the utility model is to provide a brushless DC motor with multi-angle conversion for a steering gear, so as to solve the problem proposed in the above background technology that the connection between the synchronization rod and the main shaft wears out after long-term use, resulting in reduced connection force at the connection, causing transmission gap and understeering during use.

[0004] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a brushless DC motor with multi-angle conversion for a steering gear, comprising a mounting base, a driving assembly and an adjusting assembly;

[0005] Wherein: a support plate is installed on the top of the mounting seat, a first mounting hole and a second mounting hole are opened on the surface of the support plate, and a bearing seat is provided on one side of the bottom of the mounting seat;

[0014] (1) A first mounting hole and a second mounting hole are provided on the surface of the support plate, which is convenient for providing mounting support for the driving assembly.
