Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, specifically relating to a multi-axis high-efficiency roller press speed reducer. Background Technology

[0002] In the cement grinding process, the cement batching station feeds the proportioned materials into a V-type air classifier. Materials meeting the required fineness are selected and then fed into a ball mill for further grinding. Materials not meeting the requirements are sent from the V-type air classifier to a roller press for crushing and then back to the V-type air classifier for further selection. The roller press is connected to a speed reducer. To improve the crushing efficiency and effect of the roller press, a multi-shaft roller press is typically used. A multi-shaft roller press is generally connected to a speed reducer, with the output shaft of the speed reducer connected to the input shaft of the roller press, driving multiple pressure rollers to rotate. This increases the pressure on the speed reducer, thus requiring higher stability in the connection between the output and input shafts. Existing ordinary couplings cannot meet this requirement. Therefore, a high-efficiency multi-shaft roller press speed reducer is needed to solve the aforementioned technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a multi-axis high-efficiency roller press reducer, comprising a roller press and a reducer. The input shaft of the roller press and the output shaft of the reducer are connected by a coupling. The coupling includes a first connecting plate and a second connecting plate. The first connecting plate is fixedly connected to the output shaft, and the second connecting plate is fixedly connected to the input shaft. The first and second connecting plates are provided with multiple pairs of corresponding threaded holes, and bolts are fitted into the threaded holes.

[0004] The first connecting plate has multiple grooves, evenly distributed on a circumference with the same center as the connecting plate. Each groove contains a limiting post, one end of which is always located within the groove and connected to it via a compression spring. The second connecting plate has multiple grooves, each corresponding to a groove. The cooperation of the limiting post and the grooves provides positioning and stability during the installation of the first and second connecting plates, making installation more convenient and precise, and improving efficiency. When the geared motor drives the input shaft of the roller press, the limiting post can share the force on the bolt, further improving the stability of the equipment during rotation.

[0005] Preferably, the end of the limiting post facing the connecting disc is provided with a universal ball bearing. This arrangement reduces friction between the limiting post and the connecting disc, thus reducing wear on the equipment.

[0006] Preferably, the outer ring surface of the connecting disc one is provided with multiple slots one, which are evenly distributed along the circumference of the connecting disc one. A retaining strip is hinged to each slot one via a hinge shaft. The end of the retaining strip is provided with a threaded hole two. The outer ring surface of the connecting disc two is provided with multiple slots two, each corresponding to a slot one. Each slot two is provided with a threaded hole three that mates with the threaded hole two. The retaining strip is detachably connected to the threaded hole three via a bolt two. This arrangement further improves the reliability and stability of the connection between the connecting disc one and the connecting disc two, and enhances the safety of the equipment during use.

[0007] This invention also includes other components that enable the multi-axis high-efficiency roller press reducer to function properly, all of which are conventional techniques in the field. Furthermore, any devices or components not specified in this invention, such as universal ball bearings, employ conventional techniques and equipment in the field.

[0008] Working Principle: When installing connecting disc one and connecting disc two, as they approach each other, the limiting post retracts into groove one under pressure. The geared motor drives connecting disc one to rotate slowly, or connecting disc two can be rotated slowly manually until groove one and groove two align. At this point, the limiting post extends from groove one and enters groove two under the action of a compression spring, restricting the rotation of either connecting disc one or connecting disc two. Rotation of either connecting disc one or connecting disc two then stops. The threaded holes one on connecting disc one and connecting disc two are now in a one-to-one correspondence, facilitating the fixing of connecting disc one and connecting disc two together with bolt one. During the above process, when connecting the output shaft and input shaft, it is not necessary to pre-align connecting disc one and connecting disc two, making installation quicker and simpler. Simultaneously, when the geared motor drives the output shaft and input shaft to rotate, the limiting post can share the pressure of bolt one, improving the reliability and stability of the device during use.

[0009] The beneficial effects of this utility model are: the structure is reasonable and simple, the first connecting plate is fixed to the output shaft, and the second connecting plate is fixed to the input shaft. When fixing the first connecting plate and the second connecting plate, the positioning and stabilizing effect is achieved by the cooperation of the limiting post and the second groove, making the installation more convenient and accurate and improving the installation efficiency; the connection between the first connecting plate and the second connecting plate is more reliable and stable, improving the stability of use and facilitating the efficient operation of the multi-axis roller press.

[0018] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0019] Example 1

[0020] like Figure 1-3 As shown, this utility model provides a multi-axis high-efficiency roller press reducer, including a roller press and a reducer. The input shaft 2 of the roller press and the output shaft 1 of the reducer are connected by a coupling. The coupling includes a connecting disc 3 and a connecting disc 4. The connecting disc 3 is fixedly connected to the output shaft 1 (it can be integrally formed or fixedly connected by bolts). The connecting disc 4 is fixedly connected to the input shaft 2 (it can be integrally formed or fixedly connected by bolts) to avoid loosening or slippage between the output shaft and the connecting disc 3. The connecting disc 3 and the connecting disc 4 are provided with multiple pairs of corresponding threaded holes 6, and bolts 5 are fitted into the threaded holes 6.

[0021] The connecting disc 3 has multiple grooves 8 evenly distributed on a circumference concentric with the connecting disc 3. Each groove 8 contains a limiting post 15, one end of which is always located within the groove 8 and connected to it via a compression spring 7. The connecting disc 4 has multiple grooves 2, each corresponding to one of the grooves 8. The cooperation of the limiting post 15 and the grooves 2 provides positioning and stability during the installation of the connecting discs 3 and 4, making installation more convenient and precise, and improving installation efficiency. When the geared motor drives the input shaft 2 of the roller press to rotate, the limiting post 15 can share the force on the bolt 5, further improving the stability of the equipment during rotation.

[0022] The end of the limiting post 15 facing the connecting plate 2 4 is provided with a universal ball bearing 11. This arrangement reduces the friction between the limiting post 15 and the connecting plate 2 4, thereby reducing wear on the equipment.

[0023] When installing connecting disc one and connecting disc two, connecting disc one and connecting disc two are brought close together. Under pressure, the limiting post retracts into groove one. The reduction motor drives connecting disc one to rotate slowly, or connecting disc two is rotated slowly manually, until groove one and groove two correspond. At this time, the limiting post extends out of groove one and enters groove two under the action of the compression spring, restricting the rotation of connecting disc one or connecting disc two. At this time, the rotation of connecting disc one or connecting disc two stops. The threaded holes one on connecting disc one and connecting disc two are in a one-to-one correspondence state, which makes it easy to fix connecting disc one and connecting disc two together with bolt one.

[0024] Example 2

[0025] like Figure 4-6 As shown, the difference between this embodiment and Embodiment 1 is that the outer ring surface of the connecting disk 3 has multiple slots 14, which are evenly distributed along the circumference of the connecting disk 3. A retaining strip 9 is hinged to each slot via a hinge shaft. The end of the retaining strip 9 has a threaded hole 2. The outer ring surface of the connecting disk 4 has multiple slots 13, which correspond one-to-one with slots 14. Each slot 13 has a threaded hole 3 12 that mates with the threaded hole 2. The retaining strip 9 is detachably connected to the threaded hole 3 12 via a bolt 2 10. This design further improves the reliability and stability of the connection between the connecting disk 3 and the connecting disk 4, enhancing the safety of the equipment during use.

[0026] The output shaft, input shaft, and universal ball bearings in the above embodiments are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical documents, which are all existing technologies.

[0027] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
