Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a speed reducer power output shaft that is easy to install. Background Technology

[0002] In the steel processing industry, lathes are equipment used to process metals (especially steel). They mainly cut steel workpieces by means of the relative movement between the cutting tool and the workpiece to obtain parts that meet the requirements of size, shape and surface accuracy.

[0003] Furthermore, the core function of a lathe is to transform "rough blanks" into "finished / semi-finished products." By machining steel billets (such as round bars and forgings), it precisely controls dimensions (diameter, length), shape (cylinder, cone, curved surface), and surface accuracy to meet subsequent assembly or usage requirements. For example, round steel billets produced by steel mills need to be machined into parts such as drive shafts and bolts before they can be used in the manufacture of machine tools, automobiles, and other equipment, playing a vital role in the steel processing industry.

[0004] However, in existing designs, when the power output shaft mates with the gear coupling, the gear coupling uses threaded holes on its side wall to allow a set screw to press against the outer wall of the first connecting shaft, thus fixing the gear coupling's position. This design presents challenges: the position is difficult to determine during installation, and the set screw is prone to loosening, causing axial movement of the gear coupling during use.

[0005] Therefore, the gear coupling and reducer power output shaft of the existing lathe tailstock are not easy to install and position and are prone to axial movement, which can cause mechanical failure. Utility Model Content

[0006] In order to solve the technical problems of the gear coupling and reducer power output shaft of the lathe tailstock being difficult to install and position and prone to axial movement in the prior art, this utility model provides a reducer power output shaft that is easy to install.

[0007] The present invention provides a speed reducer power output shaft that is easy to install, using the following technical solution:

[0008] A speed reducer power output shaft that is easy to install includes a motor and a speed reducer disposed on the side of the motor. A speed reducer flange is disposed on the side of the speed reducer, and a power output shaft is disposed at the center of the speed reducer flange. It also includes a gear coupling that is fixedly connected to the power output shaft. An anti-movement structure is disposed at the end of the power output shaft to fix the installation position of the gear coupling and prevent the gear coupling from moving.

[0009] By adopting the above technical solution, the position of the gear coupling can be fixed by the cooperation of the anti-movement structure and the power output shaft, thus preventing the gear coupling from moving during use.

[0010] Furthermore, the power output shaft includes a first connecting shaft located at the center of the reducer flange and a second connecting shaft located at the end of the first connecting shaft. The outer diameter of the second connecting shaft is smaller than that of the first connecting shaft, so that a stop step is formed at the end of the first connecting shaft.

[0011] By adopting the above technical solution, the gear coupling is positioned and fixed on one side by using a stop step.

[0012] Furthermore, the second connecting shaft side has a pin block.

[0013] By adopting the above technical solution, the axial rotation of the gear coupling can be prevented during use by setting a pin block.

[0014] Furthermore, an anti-running structure is provided at the end of the second connecting shaft that is away from the first connecting shaft to prevent the gear coupling from running along the track.

[0015] By adopting the above technical solution, the other end of the gear coupling is fixed by an anti-movement structure.

[0016] Furthermore, the anti-slip structure is a locking washer provided at the end of the second connecting shaft.

[0017] By adopting the above technical solution, the anti-movement structure is set as a locking gasket to facilitate subsequent processing and use.

[0018] Furthermore, the locking washer has a circular through hole at its center, and a locking positioning hole is provided at the end of the second connecting shaft, which is opposite to the circular hole in the locking washer. The bolt is passed through the circular hole in the locking washer and locked in the locking positioning hole, thereby fixing the locking washer to the end of the second connecting shaft.

[0019] By adopting the above technical solution, the gear coupling can be fixed and stopped by using bolts and locking washers to prevent the gear coupling from moving during use.

[0020] Furthermore, the gear coupling includes a shaft and a gear fixedly disposed at the end of the shaft. The shaft has a first mounting hole inside, and the gear has a second mounting hole inside. The first mounting hole and the second mounting hole communicate with each other, and the diameter of the first mounting hole is larger than the diameter of the second mounting hole.

[0021] By adopting the above technical solution: when in use, the first mounting hole is sleeved on the outside of the first connecting shaft, the second mounting hole is sleeved on the outside of the second connecting shaft, and the stop step at the end of the first connecting shaft stops the second mounting hole, thereby initially defining the installation position of the gear coupling.

[0022] Furthermore, the inner wall of the second mounting hole in the gear has a groove corresponding to the pin block.

[0023] By adopting the above technical solution, the axial position of the gear coupling is fixed by embedding the pin block into the slot, so that the gear coupling can rotate synchronously with the power output shaft.

[0024] In summary, the beneficial effects of this utility model are as follows:

[0025] This invention features an anti-slip structure, specifically a locking washer designed for easy machining and use. In operation, the gear coupling is fitted onto the outside of the power output shaft. A stop step at the end of the first connecting shaft stops one end of the gear coupling. Simultaneously, a pin is inserted into a groove in the gear coupling to fix its axial position, allowing the gear coupling and power output shaft to rotate synchronously. The locking washer is then installed at the end of the second connecting shaft, and a bolt passes through the central hole of the locking washer and locks it in the locking positioning hole to fix its position. The locking washer also secures the other end of the gear coupling, thus forming a fixed connection between the gear coupling and the power output shaft.

[0026] This invention improves the power output shaft by adding a stop step at its end. This stop step stops one end of the gear coupling. Additionally, a locking and positioning hole is added to the end of the second connecting shaft. A locking washer is installed in the locking and positioning hole, and the locking washer stops the other end of the gear coupling, thus achieving positioning and fixation of both ends of the gear coupling. Through these design improvements, the problem of axial movement and difficulty in installation and positioning of the lathe tailstock gear coupling is completely solved. Attached Figure Description

[0035] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0036] Example: Figures 1-7 The diagram shows a gearbox power output shaft that is easy to install.

[0037] Reference Figures 1-7 As shown, a gear reducer power output shaft that is easy to install is based on a redesign and manufacture of the lathe tailstock gear reducer power output shaft 4, thereby changing the current situation where the lathe gear coupling 8 and the gear reducer power output shaft 4 are not easy to install and position and are prone to axial movement. It includes: a motor 2 and a gear reducer 3 located on the side of the motor 2, a gear reducer flange 1 located on the side of the gear reducer 3, and a power output shaft 4 located at the center of the gear reducer flange 1; it also includes a gear coupling 8 that is fixedly connected to the power output shaft 4.

[0038] Specifically, refer to Figure 3 and Figure 4 As shown, the power output shaft 4 includes a first connecting shaft 5 located at the center of the reducer flange 1 and a second connecting shaft 51 located at the end of the first connecting shaft 5. The outer diameter of the second connecting shaft 51 is smaller than that of the first connecting shaft 5, forming a stop step at the end of the first connecting shaft 5, thereby facilitating the positioning and fixing of the subsequent gear coupling 8. Furthermore, the second connecting shaft 51 has a pin block 511 on its side, which prevents the gear coupling 8 connected to the power output shaft 4 from rotating axially during use.

[0039] Moreover, refer to Figure 4 and Figure 5As shown, an anti-movement structure is provided at the end of the second connecting shaft 51 away from the first connecting shaft 5 to prevent the gear coupling 8 from moving. Preferably, the anti-movement structure is a locking washer 7 located at the end of the second connecting shaft 51. Specifically, the locking washer 7 is a circular plate structure with a circular through hole at its center. A locking positioning hole 6 is provided at the end of the second connecting shaft 51, opposite to the circular hole in the locking washer 7. A bolt is passed through the circular hole in the locking washer 7 and locked into the locking positioning hole 6, thereby fixing the locking washer 7 to the end of the second connecting shaft 51. Furthermore, the shape of the locking washer 7 can be, but is not limited to, a circular structure; it can also be a polygonal structure or a cross-shaped structure, as long as it can fix and stop the gear coupling 8, preventing it from moving during use.

[0040] Reference Figure 6 and Figure 7 As shown, the gear coupling 8 includes a shaft 81 and a gear 82 fixedly mounted at the end of the shaft 81. The shaft 81 has a first mounting hole, and the gear 82 has a second mounting hole. The first mounting hole and the second mounting hole communicate with each other, and the diameter of the first mounting hole is larger than the diameter of the second mounting hole. In use, the first mounting hole is fitted onto the outside of the first connecting shaft 5, and the second mounting hole is fitted onto the outside of the second connecting shaft 51. A stop step at the end of the first connecting shaft 5 stops the second mounting hole, thus initially defining the installation position of the gear coupling 8. Furthermore, the inner wall of the second mounting hole in the gear 82 has a groove 821 corresponding to the pin 511. In use, by embedding the pin 511 into the groove 821, the axial position of the gear coupling 8 is fixed, allowing the gear coupling 8 to rotate synchronously with the power output shaft 4.

[0041] In use, the gear coupling 8 is sleeved on the outside of the power output shaft 4. The stop step at the end of the first connecting shaft 5 stops one end of the gear coupling 8. At the same time, the pin block 511 is embedded in the groove 821 in the gear coupling 8 to fix the axial position of the gear coupling 8, so that the gear coupling 8 and the power output shaft 4 can rotate synchronously. Then, the locking washer 7 is installed at the end of the second connecting shaft 51, and the bolt passes through the round hole in the locking washer 7 and locks it in the locking positioning hole 6 to fix the installation position of the locking washer 7. The other end of the gear coupling 8 is fixed by the locking washer 7, so that the gear coupling 8 and the power output shaft 4 are fixedly connected.

[0042] In the original design, when the power output shaft 4 and the gear coupling 8 were coupled, the gear coupling 8 did not contact the stop step of the power output shaft 4 before the redesign of the first connecting shaft 5. Instead, a through threaded hole was provided on the side wall of the gear coupling 8, allowing a set screw to press against the outer wall of the first connecting shaft 5 through the threaded hole, thus fixing the installation position of the gear coupling 8. The disadvantages were: the position was difficult to determine during installation, and the set screw was prone to loosening, causing axial movement of the gear coupling 8 during use.

[0043] This invention improves the power output shaft 4 by adding a stop step at its end. This stop step stops one end of the gear coupling 8. Additionally, a locking and positioning hole 6 is added to the end of the second connecting shaft 51. A locking washer 7 is installed in the locking and positioning hole 6, and the locking washer 7 fixes the other end of the gear coupling 8, thus achieving positioning and fixation of both ends of the gear coupling 8. Through these design improvements, the problem of axial movement and difficulty in installation and positioning of the lathe tailstock gear coupling 8 is completely solved.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
