When teaching mechanical students, in order to let students have a deep understanding of shaft transmission, especially double universal joint shaft transmission, there is an urgent need for a shaft transmission structure for teaching demonstration, which is convenient for students to operate and observe the working process of double universal joint shaft transmission by themselves. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a shaft transmission structure for teaching demonstration, which can be used for teaching demonstration and facilitate students to observe the working process of the double universal joint shaft transmission.

[0004] The technical solution adopted by the utility model is as follows: a shaft transmission structure for teaching demonstration, including a first base, to which a first support assembly for supporting a motor and a second support assembly for supporting a driving member are respectively connected, the first support assembly includes a second base, on which a motor is provided, the second support assembly includes a third base, on which a driving member is provided, on which a rotating shaft is provided, and a double universal joint is connected between the motor and the rotating shaft.

[0005] Principle of the technical solution:

[0006] The motor is fixed on the first base through the second base, and the driving member is fixed on the first base through the third base. The rotating shafts on the motor and the driving member are connected through double universal joints. When the motor starts, the motor shaft on the motor rotates. Since the two ends of the double universal joint are respectively connected to the motor shaft on the motor and the rotating shaft on the driving member, the motor drives the double universal joints to rotate, and the double universal joints drive the rotating shaft to rotate. Students can intuitively observe the working process of the double universal joint shaft transmission when the motor shaft on the motor and the rotating shaft on the driving member are coaxial.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The first base of the utility model provides support for the second base and the third base, the second base provides support for the motor, and the third base provides support for the driving member. The second base, the motor, the double universal joint, the driving member and the rotating shaft cooperate to demonstrate the working process of the double universal joint shaft transmission, which is convenient for students to intuitively observe the working process of the double universal joint shaft transmission.

[0009] As a preferred embodiment of the utility model, the first support assembly is also used to drive the vertical position adjustment of the motor, and the first support assembly also includes a first support member, the first support member includes a first support plate, a first connecting plate and a second connecting plate respectively located at both ends of the first support plate and both rotatably connected to the second base, a first bolt having one end that can abut against the side of the second base is threadedly connected to the first connecting plate, and the motor is connected to the first support plate.

[0010] In this solution, the motor is connected to the first support plate, the first support plate is grasped by hand, and the first support plate is driven to rotate vertically, and the first support plate drives the motor to rotate vertically. Since the first connecting plate and the second connecting plate are both rotatably connected to the second base, the first support plate drives the first connecting plate and the second connecting plate to rotate, and the first support plate stops vertical rotation at a specified position. The first bolt is threadedly connected to the first connecting plate, and one end passes through the first connecting plate and abuts against the side of the second base. The first bolt limits the first connecting plate, that is, limits the first support plate, thereby realizing limiting the motor after rotation.

[0011] Beneficial effect: the first support plate can provide support for the motor, the first connecting plate and the second connecting plate are both rotatably connected to the second base, and the first connecting plate is threadedly connected to the first bolt, and the first bolt can abut against the side of the second base, so that the first support plate can be kept in the position after vertical rotation, that is, the vertical position of the motor can be adjusted. When the driving member remains in the same position, it is convenient for students to operate by hand to form an angle between the motor shaft on the motor and the rotating shaft on the driving member. Students can intuitively observe the working process of the double universal joint shaft transmission when the motor shaft on the motor and the rotating shaft on the driving member have an angle.

[0012] As a preferred embodiment of the present invention, the first bolt may be a butterfly bolt.

[0013] Beneficial effect: The first bolt can be operated quickly and conveniently without the aid of auxiliary tools.

[0015] In this solution, the hand grasps the first connecting block and drives the first connecting block to move upward. When the first connecting block moves upward, it slides with the first support column. The first connecting block is connected to the motor, and the first connecting block drives the motor to move upward. The motor shaft on the motor passes through the first through hole and the first strip hole. When the first connecting block reaches the specified position, the second bolt is threadedly connected to the first connecting block, and one end passes through the first connecting block and abuts against the side of the first support column. The second bolt limits the first connecting block, that is, limits the motor.

[0016] Beneficial effect: The first connecting block provides support for the motor. The first connecting block, the first support column and the second bolt cooperate to enable the first connecting block to remain in the position after moving up and down, that is, to achieve up and down position adjustment of the first connecting block. When the driving member remains in position unchanged, it is convenient for students to operate by hand to make the extended line of the motor shaft axis on the motor form an angle with the extended line of the rotating shaft axis on the driving member. Students can intuitively observe the working process of the double universal joint shaft transmission when the extended line of the motor shaft axis on the motor forms an angle with the extended line of the rotating shaft axis on the driving member.

[0019] In this solution, the driving member is connected to the second support plate, the second support plate is grasped by hand, and the second support plate is driven to rotate vertically, and the second support plate drives the driving member to rotate vertically. Since the third connecting plate and the fourth connecting plate are both rotatably connected to the third base, the second support plate drives the third connection and the fourth connecting plates to rotate, and the second support plate stops vertical rotation at the specified position. The third bolt is threadedly connected to the third connecting plate, and one end passes through the third connecting plate and abuts against the side of the third base. The third bolt limits the third connecting plate, that is, limits the second support plate, thereby realizing limiting the driving member after rotation.

When the second connecting block moves upward, it slides with the second support column. The second connecting block is connected to the driving member, and the second connecting block drives the driving member to move upward. The rotating shaft on the driving member passes through the second through hole and the second strip hole. When the second connecting block reaches the specified position, the fourth bolt is threadedly connected to the second connecting block, and one end passes through the second connecting block and abuts against the side of the second support column.
