Description

Technical Field

[0001] This application relates to the field of motor equipment technology, specifically to a novel high-efficiency connected motor. Background Technology

[0002] The motor shaft extension, also known as the motor output shaft end, is the exposed shaft section of the motor rotor shaft extending beyond the front cover. As a core connecting component for motor power output, it is mainly used to connect various loads such as couplings, pulleys, sprockets, gears, fan impellers, water pump impellers, agitator mechanisms, and speed reduction devices to transmit torque and speed. To facilitate load connection, the shaft extension typically requires appropriate structural design, such as keyways or raised keys. However, existing motor shaft extensions can only accommodate a single type of load and cannot adapt to multiple different types of loads. Therefore, it is necessary to design a shaft extension that can adapt to multiple loads, as well as a motor with such a design. Summary of the Invention

[0004] The shaft extension body is arranged in the left-right direction and includes a cylindrical shaft, a lower keyway arranged axially on the right side of the lower edge of the shaft extension body, a rectangular inner cavity arranged inside the cylindrical shaft, a rectangular narrow hole arranged at the upper end of the rectangular inner cavity and with a reduced front-to-back size, and a rectangular side hole arranged on the right side of the rectangular inner cavity. The upper end of the rectangular side hole is provided with a locking top hole, and the right end of the cylindrical shaft is provided with a horizontal countersunk hole corresponding to the locking top hole. The left side of the horizontal countersunk hole is provided with an internal thread.

[0005] The active component includes a rectangular slider slidably disposed within a rectangular side hole. The left half of the rectangular slider is provided with active insert rods at the front and rear, respectively.

The right half of the active screw is provided with a narrow-diameter guide rod, and the right end of the narrow-diameter guide rod is provided with an internal hexagon terminal. The outer wall of the internal hexagon terminal is provided with a limiting ring groove in the middle. A perforated square plate is also sleeved on the limiting ring groove. The inner wall of the circular hole of the perforated square plate is provided with a limiting protrusion that engages with the limiting ring groove.

[0006] The locking assembly includes a locking plate and an anti-loosening bolt; the locking plate includes a plate body inserted into the locking top hole, a lower stop groove located below the plate body and engaging with a narrow-diameter guide rod, and an upper locking groove located above the plate body. The lower edge of the upper locking groove is provided with a locking strip, and the lower end of the plate body is provided with an elastic pad; the anti-loosening bolt is inserted into a horizontal countersunk hole and threaded with an internal thread, and the anti-loosening bolt is locked in the upper locking groove; the anti-loosening bolt includes a bolt body threaded with an internal thread and locking slots evenly distributed circumferentially on the right half of the bolt body and engaging with the locking strip.

[0007] The driven key body includes a rectangular key base slidably disposed in a rectangular cavity, a rectangular through hole disposed in the key base along the left and right direction and engaged with a rectangular slider, and an upper convex key disposed above the key base and engaged with a rectangular narrow hole. The rectangular through hole is provided with driven oblique grooves at the front and rear, respectively, which engage with the corresponding active insert rod.

[0008] The beneficial effects of the technical solution of this invention: The present invention provides a novel high-efficiency motor connection, which provides two external load connection structures: convex key and keyway, and can be quickly switched for convenient and efficient connection.

[0009] The present invention discloses a novel high-efficiency motor with convenient connection mode switching: rotating the internal hexagonal terminal can drive the rectangular slider and the active plug rod to move, thereby driving the upper convex key to move upward through the driven inclined slot, and the upward movement of the upper convex key can realize the convex key connection; conversely, when the upper convex key moves downward, the lower keyway can be used for keyway connection.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0024] The novel high-efficiency motor described in this case provides two load connection methods, keyway and keyway, in its shaft extension assembly 8, and allows for quick switching: Mode 1, lower key slot 12 connection: Under normal conditions, the rectangular slider 21 and the active insertion rod 22 of the active component 2 are in the right position, and the key base 41 and the upper convex key 43 are in the low position. The cylindrical shaft 11 has no protrusions on its circumference, only the lower keyway 12, through which the connection to the external load can be achieved (the load provides the convex key).

[0025] Mode 2, top-mounted convex key 43 connection: Since the narrow-diameter optical rod 25 is locked in axial movement by the lower stop groove 312, it will not move axially when the internal hexagon terminal 26 and the drive screw 24 are rotated. The active screw 24 acts on the sliding screw hole 23 to drive the rectangular slider 21 and the active insertion rod 22 to move to the left. The active insertion rod 22 acts on the driven inclined groove 44, thereby driving the key base 41 and the upper convex key 43 to move upward until the upper convex key 43 extends out from the rectangular narrow hole 14. The connection to the external load can be realized through the upper convex key 43 (the load provides the keyway).

[0026] It should be noted that the lower stop groove 312 of the locking assembly 3 can lock the axial movement freedom of the active screw 24 and the internal hexagon terminal 26 through the narrow diameter light rod 25, thereby realizing the screw connection between the active screw 24 and the slider screw hole 23.

[0027] Furthermore, the posture of the locking component 3 can achieve self-locking: After inserting the insert plate body 311 downward into the locking top hole 16, continue to press down to compress the elastic pad 315, so that the insert plate body 311 is in the lowest position. Insert the anti-loosening bolt 32 into the horizontal countersunk hole 17 to the left. After passing through the upper locking groove 313, the anti-loosening bolt 32 is threadedly connected to the internal thread 18. At this time, since the insert plate body 311 is in the lowest position, the locking insert strip 314 will not interfere with the locking slot 322. When the downward pressure on the insert plate body 311 is released, the insert plate body 311, the upper locking groove 313, and the locking strip 314 move upward. The locking strip 314 is inserted into the locking slot 322, locking the rotational freedom of the anti-loosening bolt 32. The anti-loosening bolt 32 will not fall off, and the insert plate body 311 is effectively prevented from falling off.

[0028] As a further implementation, the shaft extension body 1 is formed by splicing together a symmetrical structure, that is, the semi-circular cross-section structure of the front half and the semi-circular cross-section structure of the rear half of the shaft extension body 1 are spliced ​​together and then fixed together by bolts. This structure allows the driven key 4 to be removed and replaced.
