Drawings
Fig. 1 is a schematic structural diagram of a self-centering connection structure of an engine and a motor according to an embodiment of the present invention;
fig. 2 is a cross-sectional view of fig. 1A-a.
Wherein, 1 is an engine crank, 2 is a motor rotor shaft, 3 is a connecting seat, 301 is a connecting concave tooth, 4 is a connecting hub, 401 is a connecting convex tooth, and 5 is a clamping ring.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 and 2, a self-centering connection structure of an engine and a motor comprises an engine crankshaft 1 and a motor rotor shaft 2, and is characterized in that a connection seat 3 is fixedly arranged at one end of the engine crankshaft 1, a connection hole is formed in the connection seat 3, the connection hole and the engine crankshaft 1 are coaxially arranged, a plurality of connection concave teeth 301 distributed at intervals along the circumferential direction are arranged on the inner wall of the connection hole, the self-centering connection structure further comprises a connection hub 4 installed in the connection hole, a connection convex tooth 401 in transmission matched with the connection concave teeth 301 is arranged on the periphery of the connection hub 4, the connection hub 4 is in clearance fit with the connection hole of the connection seat, a mounting hole is formed in the connection hub 4, the motor rotor shaft 2 is installed in the mounting hole of the connection hub 4, and the motor rotor shaft 2 and the connection hub 4 are coaxially arranged.
Therefore, the structure is simple, and compared with the existing structure, the flywheel disc does not need to be introduced, so that the cost is reduced. The main transmission is realized through the cooperation of connecting hole and connection hub, connects the gap setting between the concave tooth and the connection convex tooth, can realize automatic centering at the high number rotation in-process like this, ensures to connect driven axiality.
In this embodiment, the coupling concave teeth 301 and the coupling convex teeth 401 are involute gear teeth.
In this way, sufficient strength is ensured for the transmission, and excessive shock at the time of starting is relieved.
In this embodiment, the number of the coupling concave teeth 301 is six, and six coupling concave teeth are uniformly spaced.
