Description

Technical Field

[0001] The present application relates to the field of textile machinery, and more particularly, to a novel spindle drive mechanism. Background Art

[0002] A spindle is one of the main components for twisting and winding on a spinning frame. In the spindle drive mechanism in the related art, such as the spindle drive mechanism of the walking frame type spinning frame disclosed in the Chinese invention patent application No. CN200610116120.3, a motor and a synchronous pulley installed at its transmission end are mainly used as driving forces to drive the spindle. However, during the operation of the motor, the shaft end has to bear a large load and inertia force. In the spindle drive mechanism of the above solution, the output shaft of the motor lacks a corresponding rotational support protection structure, which easily leads to unstable operation of the motor and even causes equipment failures. Summary of the Utility Model

[0003] To make up for the above deficiencies, the present application provides a novel spindle drive mechanism, mainly by adding an additional bearing strengthening support member on the synchronous pulley to play a protective role for the output shaft of the motor.

[0004] The solution of the present application provides a novel spindle drive mechanism, including a motor mounting plate and a motor mounted thereon. The output end of the motor is provided with a motor output shaft, and a synchronous pulley is arranged outside the motor output shaft. A bearing strengthening support member is also included;

[0005] The bearing strengthening support member includes a bearing fixing seat provided on the motor mounting plate. A bearing is assembled in the inner ring of the bearing fixing seat, and the synchronous pulley is assembled between the inner ring of the bearing and the outer wall of the motor output shaft.

[0006] Preferably, an annular avoidance cavity is formed at one end of the synchronous pulley close to the motor. The bearing is arranged inside the annular avoidance cavity, and one end of the bearing fixing seat extends into the annular avoidance cavity.

[0007] Preferably, a fixing sleeve is provided on the outer peripheral side of the motor output shaft by interference fit. The fixing sleeve is divided into upper and lower sections. The upper section is designed as a frustum of a cone, and the lower section is designed as a cylinder. The diameter of the lower section is larger than that of the upper section. The inner ring of the synchronous pulley is attached to the outer wall of the upper section of the fixing sleeve, and an annular step groove is formed at the bottom end of the synchronous pulley to cooperate with the lower section of the fixing sleeve.

[0008] Preferably, the bearing fixing seat is fixedly connected to the motor mounting plate by a bolt and nut structure.

[0009] Preferably, a through hole is formed on the motor mounting plate, and the motor output shaft can pass through the through hole.

[0010] Beneficial effects: The present application provides a novel spindle drive mechanism. As can be seen from the sectional views of Figure 3 and Figure 4 , the bearing fixing seat is fixed on the motor mounting plate. The synchronous pulley fits well with the inner ring of the bearing, and then the outer ring of the bearing fits well with the bearing fixing seat. Moreover, the inner side of the synchronous pulley is assembled outside the motor output shaft. Such a design adds an additional bearing strengthening support member to the synchronous pulley, playing a role in protecting the motor output shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0018] Please refer to Figures 1-4 , the present application provides a novel spindle drive mechanism, including a motor mounting plate 1 and a motor 2 mounted thereon. The output end of the motor 2 is provided with a motor output shaft 6, and a synchronous pulley 3 is arranged outside the motor output shaft 6. It further includes a bearing strengthening support member 4;

[0019] The bearing strengthening support member 4 includes a bearing fixing seat 41 provided on the motor mounting plate 1. A bearing 42 is assembled inside the inner ring of the bearing fixing seat 41, and a synchronous pulley 3 is assembled between the inner ring of the bearing 42 and the outer wall of the motor output shaft 6.

[0020] In this embodiment, referring to Figure 3 and Figure 4 the cross-sectional view, the bearing fixing seat 41 is fixed on the motor mounting plate 1. The synchronous pulley 3 is well-mated with the inner ring of the bearing 42, and then the outer ring of the bearing 42 is well-mated with the bearing fixing seat 41. Moreover, the inner side of the synchronous pulley 3 is assembled outside the motor output shaft 6. Such a design is to additionally add a bearing strengthening support member 4 to the synchronous pulley 3, which plays a role in protecting the motor output shaft 6.

[0021] Please refer to Figure 3 and Figure 4 , an annular avoidance cavity 31 is provided at one end of the synchronous pulley 3 close to the motor 2. The bearing 42 is arranged inside the annular avoidance cavity 31, and one end of the bearing fixing seat 41 extends into the annular avoidance cavity 31. Specifically, with the design of the annular avoidance cavity 31, the synchronous pulley 3 can be better installed and mated with the bearing 42 and the bearing fixing seat 41.

[0022] Please refer to Figure 3 and Figure 4 , an interference fit fixing sleeve 5 is provided on the outer peripheral side of the motor output shaft 6. The fixing sleeve 5 is divided into upper and lower sections. The upper section is designed as a frustum of a cone, and the lower section is designed as a cylinder, and the diameter of the lower section is larger than that of the upper section. The inner ring of the synchronous pulley 3 is in contact with the outer wall of the upper section of the fixing sleeve 5, and an annular step notch matching the lower section of the fixing sleeve 5 is provided at the bottom end of the synchronous pulley 3. Specifically, with the shape matching of the inner ring and the bottom end of the synchronous pulley 3 with the fixing sleeve 5, it is beneficial to reduce the probability of the synchronous pulley 3 slipping outwards from the motor output shaft 6, indirectly increasing the installation stability of the synchronous pulley 3.

[0023] The bearing fixing seat 41 is fixedly connected to the motor mounting plate 1 by a bolt and nut structure. Specifically, such a design can firmly install the bearing fixing seat 41 on the motor mounting plate 1, indirectly realizing the stability of the use of the bearing strengthening support member 4.

[0024] A through hole is provided on the motor mounting plate 1, and the motor output shaft 6 can pass through the through hole.

[0025] When this application is in use:

[0026] The bearing fixing seat 41 is fixed on the motor mounting plate 1. The synchronous pulley 3 is well-mated with the inner ring of the bearing 42, and then the outer ring of the bearing 42 is well-mated with the bearing fixing seat 41. Moreover, the inner side of the synchronous pulley 3 is assembled outside the motor output shaft 6. Such a design is to additionally add a bearing strengthening support member 4 to the synchronous pulley 3, which plays a role in protecting the motor output shaft 6.
