Description

Technical Field

[0001] This utility model relates to the field of sintering machine technology, specifically to a flexible transmission combination connecting sleeve for a sintering machine. Background Technology

[0002] The sintering machine is a crucial piece of equipment in the metallurgical industry. Its flexible transmission system is the core component driving the sintering machine trolley, and its reliability and stability directly affect the continuity and efficiency of the entire production line. This transmission system typically connects the head wheel main drive shaft to the main gear of the flexible transmission large gear via a connecting sleeve to transmit enormous torque.

[0003] However, for connecting sleeves that use the expansion principle, their performance is highly dependent on the uniformity of the preload of each fastening bolt. In actual operation, it is difficult to guarantee the absolute uniformity of torque by manually tightening each bolt one by one. Any slight torque deviation will lead to uneven distribution of contact stress on the inner and outer conical surfaces of the expansion sleeve. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a flexible transmission combined connecting sleeve for sintering machines, which solves the technical problem of uneven stress distribution on the inner and outer conical surfaces of the expansion sleeve caused by torque deviation when manually tightening bolts.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: This utility model provides a flexible transmission combination connecting sleeve for a sintering machine.

[0006] This utility model provides a flexible transmission combination connecting sleeve for a sintering machine, comprising: The connecting sleeve body includes a connecting seat for cooperating with the shaft of the transmission device, and a collar sleeved on the outer surface of the connecting seat. The connecting seat and the collar are connected by at least one set of bolt threads, and the connecting seat, the collar and the bolts together form a tightening fit structure. The outer surface of the collar is fitted with a transmission component with a flexible transmission structure; A synchronization component is disposed on the collar and includes a rotating cover that can rotate relative to the collar. The rotating cover is provided with a transmission structure that is linked and engaged with all the bolts to drive all the bolts to rotate synchronously. The synchronization component also includes a locking structure for limiting the rotation of the rotating cover.

[0007] Optionally, the transmission structure includes: A groove is formed on the surface of the bolt, and teeth are provided on the inner wall of the rotating cover. The teeth are embedded in the groove to achieve linkage between the rotating cover and the bolt.

[0008] Optionally, the collar surface is provided with a movable groove, the rear end of the rotating cover is embedded in the movable groove, and the cross-sectional shape of the rear end of the rotating cover is a horizontal L-shape to assist the rotating cover in stable rotation.

[0009] Optionally, a spring is fixedly connected to the inner wall of the movable groove, and the other end of the spring abuts against the rotating cover to provide an elastic force for the rotating cover to return to its original position.

[0010] Optionally, the locking structure includes: An annular groove is formed on the inner wall of the movable groove on the surface of the collar, and a locking ring is disposed at the rear end of the rotating cover. The locking ring is located in the annular groove to restrict the rotation of the rotating cover.

[0011] Optionally, the locking ring has multiple locking teeth arranged in a circular array on the side near the annular groove. The locking teeth are used to increase the friction between the locking ring and the inner wall of the annular groove.

[0012] Optionally, the synchronization component further includes: A drive sleeve is disposed on the front side of the rotating cover, and a hexagonal groove is formed on the surface of the drive sleeve.

[0013] Optionally, the transmission component of the flexible transmission structure is a synchronous pulley, which is fixedly sleeved on the outer surface of the collar to realize power transmission with the flexible transmission system.

[0014] Optionally, multiple sets of bolts are evenly distributed along the circumference of the connecting seat and the collar to ensure uniform force distribution when the connecting seat and the collar are tightened together.

[0015] (III) Beneficial Effects The beneficial effects of this utility model are: (1) By using the synchronous components set on the surface of the collar, especially by driving the rotating cover, the teeth on its inner wall mesh synchronously and drive all bolts to rotate, the synchronous and equal-angle tightening of multiple fastening bolts of the expansion sleeve is achieved. This design fundamentally solves the problem of uneven bolt preload caused by traditional manual tightening one by one from a mechanical structure perspective, ensuring the uniform distribution of contact stress on the inner and outer conical surfaces of the expansion sleeve, thereby significantly improving the torque transmission capacity and reliability.

[0016] (2) Through the coordinated design of spring and locking ring, after the bolt is locked in place by the rotating cover, the locking ring can effectively self-lock by the friction generated by its teeth and the inner wall of the annular groove, which firmly restricts the accidental rotation of the rotating cover.

[0019] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0020] Exemplary embodiments of the present invention will be described in more detail below. While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the full scope of the present invention can be conveyed to those skilled in the art.

[0021] like Figures 1 to 6As shown, this embodiment proposes a flexible transmission combined connecting sleeve for a sintering machine, comprising: a connecting sleeve body, the connecting sleeve body including a connecting seat 200 and a collar 220 sleeved on the surface of the connecting seat 200, a bolt 210 threadedly connecting the connecting seat 200 and the collar 220, the connecting sleeve, the collar 220 and the bolt 210 being combined into an expansion sleeve structure; a shaft 100 of a transmission device is provided inside the connecting seat 200, and a flexible conventional structure synchronous wheel 300 is provided on the outer surface of the collar 220, the synchronous wheel 300 being fixedly connected to the collar 220 by a key connection or interference fit to transmit the torque required for the operation of the sintering machine; 6-8 bolts 210 are evenly distributed along the circumference of the connecting seat 200 and the collar 220. The bolt 210 has one end that passes through the collar 220 and is threaded to the side wall of the connecting seat 200. The tightening action of the bolt 210 can drive the collar 220 to move axially relative to the connecting seat 200, so that the tapered surfaces of the connecting seat 200 and the collar 220 produce elastic deformation, thereby forming a tightening fit structure and realizing the firm fixation of the connecting sleeve body and the shaft 100.

[0022] When it is necessary to fasten the expansion sleeve to the shaft 100, the operator first puts the connecting seat 200 on the shaft 100 and installs the timing pulley 300 outside the collar 220.

[0023] Synchronization component 400 is mounted on collar 220 and is used to drive all bolts 210 to rotate synchronously, ensuring that the preload of each bolt 210 is uniform. Specifically, the synchronization component 400 includes a rotating cover 410 disposed on the surface of the collar 220. The inner wall of the rotating cover 410 is provided with teeth 412 for synchronously controlling the rotation of multiple bolts 210. A locking ring 414 is provided at the rear end of the rotating cover 410 for self-locking and limiting the rotating cover 410.

[0024] The synchronization component 400 also includes a drive sleeve 411 disposed on the front side of the rotating cover 410, and the surface of the drive sleeve 411 is provided with a hexagonal groove.

[0025] Insert the hexagonal head of the external drive tool into the internal hexagonal groove of the drive sleeve 411 and apply pressure backward, causing the rotating cover 410 to drive the locking ring 414 to move backward within the movable groove 420, causing the locking ring 414 to disengage from the inner wall of the movable groove 420. Then, start or rotate the drive tool, and the torque generated by the drive tool is transmitted to the rotating cover 410 through the drive sleeve 411, causing the entire rotating cover 410 to rotate. The internal teeth 412 of the rotating cover 410 drive all bolts 210 to rotate together synchronously and at equal angles through meshing. Since the bolts 210 and the connecting seat 200 are threaded, the rotation of the bolts 210 will pull the collar 220 to move axially, causing the conical surface of the expansion sleeve to produce uniform elastic deformation, thereby achieving tightening. This process ensures that the preload of all bolts 210 is completely consistent, fundamentally avoiding the problem of uneven contact stress distribution caused by uneven torque. The synchronization component 400 also includes a slot 413 formed on the surface of the bolt 210. Multiple slots 413 are formed in a ring array, and teeth 412 are embedded in the slots 413.

[0026] The synchronization component 400 also includes a movable groove 420 formed on the surface of the collar 220. The rear end cross-section of the rotating cover 410 is a horizontal L-shaped design, and the rear end of the rotating cover 410 is embedded in the movable groove 420. A spring 421 is fixedly connected to the inner wall of the movable groove 420, and the other end of the spring 421 abuts against the rotating cover 410. Through the above design, the rotating cover 410 can be made more stable when rotating.

[0027] The inner wall of the movable groove 420 is provided with an annular groove, and the locking ring 414 is located in the annular groove.

[0028] Once the bolt 210 is tightened to the predetermined torque, the driving tool is removed. At this time, the spring 421 drives the rotating cover 410 to return to its original position. The locking ring 414 at the rear of the rotating cover 410 will re-abut against the inner wall of the movable groove 420, generating a huge frictional torque and forming an effective mechanical self-locking. This self-locking effect firmly restricts any accidental rotation of the rotating cover 410, thereby eliminating the possibility of the bolt 210 loosening due to vibration and ensuring the long-term stability of the clamping force of the expansion sleeve.

[0029] The locking ring 414 has multiple locking teeth arranged in a ring array on the side near the annular groove. The locking teeth are used to increase the friction between the locking ring 414 and the inner wall of the annular groove.

[0030] In actual operation, when it is necessary to fasten the expansion sleeve to the shaft 100, the operator first places the connecting seat 200 on the shaft 100 and installs the synchronous pulley 300 outside the collar 220. Then, the hexagonal head of the external drive tool is inserted into the inner hexagonal groove of the drive sleeve 411 and pressure is applied backward, causing the rotating cover 410 to drive the locking ring 414 to move backward within the movable groove 420, causing the locking ring 414 to disengage from the inner wall of the movable groove 420. Subsequently, the drive tool is started or rotated, and the torque generated by the drive tool is transmitted to the rotating cover 410 through the drive sleeve 411, causing the entire rotating cover 410 to rotate. The internal teeth 412 of the rotating cover 410 drive all bolts 210 to rotate synchronously and at equal angles through meshing. Since the bolts 210 and the connecting seat 200 are threaded, the rotation of the bolts 210 will pull the collar 220 to move axially, causing the conical surface of the expansion sleeve to produce uniform elastic deformation, thereby achieving tightening. When the bolts 210 are tightened to the predetermined torque, the driving tool is removed. At this time, the spring 421 drives the rotating cover 410 to return to its original position. The locking ring 414 at the rear of the rotating cover 410 will re-abut against the inner wall of the movable groove 420, generating a huge frictional torque and forming an effective mechanical self-locking.
