Description

Technical Field

[0001] The utility model relates to the technical field of parallel shaft reducer accessories, in particular to a parallel shaft reducer box body with high stability. Background Technique

[0002] A parallel shaft reducer is a common mechanical transmission device used to reduce the speed of a high-speed rotating input shaft and transmit it to the output shaft. The input shaft and the output shaft are designed with a parallel layout. It consists of a reducer housing, an input shaft, an output shaft, and gears, and transmits power through the meshing between the gear sets inside the reducer housing. Parallel shaft reduction boxes are widely used in the transmission systems of industrial production lines such as mines, metallurgy, textiles, and automated production lines. Because the output shaft and the input shaft of the parallel shaft reducer adopt a parallel layout design, in special scenarios, the extended part of the output shaft is relatively long, which poses a potential hazard to the stability of the transmission system. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is that the box body structure of the traditional parallel shaft reducer is fixed, resulting in relatively single traditional stability.

[0004] A parallel shaft reducer box body with high stability, including a main box body. An upper end of an outer wall on the left side of the main box body is provided with a lateral telescopic opening. A lateral assembly groove is provided on an inner side surface of the main box body. A lateral telescopic tube is slidably assembled inside the lateral telescopic opening. A lateral adjusting support rod for controlling the translation of the lateral telescopic tube is fixedly assembled inside the lateral assembly groove.

[0005] An embedded ball bearing is installed on an inner side surface of the lateral telescopic tube.

[0006] A lateral control seat matched with the lateral adjusting support rod is provided on a side wall of the lateral telescopic tube. The lateral telescopic tube is inserted into the lateral assembly groove through the lateral control seat and is slidably assembled with the lateral assembly groove.

[0007] A side-mounted assembly groove with a loading and unloading notch on the outside is provided on a side wall of the lateral control seat.

[0008] An end linkage block matched with the side-mounted assembly groove is axially fixed at a top of an extending end of the lateral adjusting support rod.

[0009] A lateral loading and unloading opening communicating with the inside of the lateral assembly groove is provided on an outer side surface of the main box body. An outer closing cover is bolted inside the lateral loading and unloading opening.

[0010] The beneficial effects of the utility model are:

[0011] (1) A high-stability parallel shaft reducer box of the present utility model is provided with an electronically controlled and controllable lateral telescopic tube at the output shaft position, which can effectively improve the stability of the output extension shaft;

[0012] (2) Adopting an electronically controlled telescopic structure design to improve the rotational stability of the output end according to the extended length of the output shaft;

[0013] (3) The device adopts a portable structure design, which is convenient for later maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present utility model will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0020] Figure 1 、 Figure 2 and Figure 3 A high-stability parallel shaft reducer box shown in the figures includes a main box body 1. An upper end of the outer wall on the left side of the main box body 1 is provided with a lateral telescopic opening 2, and a lateral assembly groove 3 is provided on the inner side surface of the main box body 1. A lateral telescopic tube 4 is slidably assembled inside the lateral telescopic opening 2, and a lateral adjustment strut 5 for controlling the translation of the lateral telescopic tube 4 is fixedly assembled inside the lateral assembly groove 3.

[0021] The lateral adjusting strut 5 controls the translation of the lateral telescopic tube 4 by expanding and contracting. When idle, the lateral telescopic tube 4 can be contracted into the main box body 1. When the output shaft is in an unstable state, the lateral adjusting strut 5 contracts, thereby controlling the lateral telescopic tube 4 to extend outwards, thus improving the external directivity of the output shaft, ensuring concentricity and improving transmission stability at the same time.

[0022] Also, when the output shaft is relatively long, the stability of the output shaft can be directly improved by controlling the lateral telescopic tube 4 to extend outwards.

[0023] To cooperate with the embedded assembly, an embedded ball bearing 6 is installed on the inner side surface of the lateral telescopic tube 4.

[0024] Circular assembly grooves are provided on both sides inside the lateral telescopic tube 4. The embedded ball bearing 6 is inserted into the circular assembly groove from the openings on both sides and is fixedly connected to the lateral telescopic tube 4.

[0025] To cooperate with the lateral linkage control, a lateral control seat 7 that cooperates with the lateral adjusting strut 5 is provided on the side wall of the lateral telescopic tube 4. The lateral telescopic tube 4 is inserted into the lateral assembly groove 3 through the lateral control seat 7 and is slidably assembled with the lateral assembly groove 3.

[0026] A lateral sinking groove for installing the lateral control seat 7 is provided on the outer arc surface of the lateral telescopic tube 4. The lateral control seat 7 is fixedly assembled with the lateral telescopic tube 4 by screwing bolts on both sides into the lateral sinking groove.

[0027] To cooperate with the lateral assembly, a side-mounted assembly groove 8 with a loading and unloading notch on the outer side is provided on the side wall of the lateral control seat 7.

[0028] To cooperate with the linkage control, an end linkage block 9 that cooperates with the side-mounted assembly groove 8 is axially fixed to the top of the protruding end of the lateral adjusting strut 5.

[0029] To cooperate with the lateral loading, unloading and maintenance, a lateral loading and unloading port connected to the inside of the lateral assembly groove 8 is provided on the outer side surface of the main box body 1. An outer closing cover 10 is fixedly bolted inside the lateral loading and unloading port.

[0030] By removing the outer closing cover 10 located inside the lateral loading and unloading port, the lateral control seat 4 and the end linkage block 9 can be very conveniently removed. The protruding end of the lateral adjusting strut 5 and the end linkage block 9 are axially fixed by a coupling, so that the end linkage block 9 can be very conveniently removed.

[0031] Inspired by the above ideal embodiments of the present invention, through the above description, relevant workers can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
