[0013] Figure 2 yes Figure 1 Magnified view of part A in FIG. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0015] A servo direct drive dry pull machine motor and reel water tray assembly connection structure that is easy to maintain, such as Figure 1 and Figure 2 As shown, it includes a motor 1, a water pan 2, a bearing seat 3, a reel 4, a flat key 5, a pressure plate 6, a main shaft 7, an upper end bearing 8, a lower end bearing 9 and a locking bolt 10;

[0016] The water pan 2 has a water pan bottom plate mounting opening 2.1 in the middle of the bottom plate, the housing of the motor 1 is fixed to the lower end surface of the water pan 2 at the water pan bottom plate mounting opening 2.1, the bearing seat 3 is fixed to the upper end surface of the water pan 2 at the water pan bottom plate mounting opening 2.1 by a plurality of locking bolts 10, the bearing seat 3 blocks the water pan bottom plate mounting opening 2.1, an upper end bearing 8 and a lower end bearing 9 are installed in the bearing seat 3, the main shaft 7 is sleeved in the inner ring of the upper end bearing 8 and the inner ring of the lower end bearing 9, the upper section of the main shaft 7 is conical, and the output shaft of the motor 1 passes through the water pan bottom plate mounting opening 2.1 and is splined to the lower section of the main shaft 7 to transmit power;

[0017] The winding drum 4 is provided with a conical mounting hole 4.1. The upper section of the main shaft 7 is matched with the conical mounting hole 4.1 of the winding drum 4 through inner and outer conical surfaces and connected through a flat key 5. A pressure plate 6 is fixed on the upper end surface of the main shaft 7.

[0018] The output shaft of the motor 1 is an external spline shaft, and the lower section of the main shaft 7 is provided with an internal spline hole, and the output shaft of the motor 1 is connected to the main shaft 7 via a spline.

[0019] In the present invention, the casing of the motor 1 and the water pan 2 are connected by screws, but the water pan assembly is formed by the water pan 2 and the bearing seat 3, and the bearing seat 3 is connected to the upper end surface of the water pan 2 by fastening bolts 10.

[0020] A first O-ring installation groove is provided on the upper end surface of the water pan 2 corresponding to the inner side of the locking bolt 10 and the position of the water pan bottom plate installation opening 2.1, and a first O-ring 11 is installed in the first O-ring installation groove.
