Description

Technical Field

[0001] This utility model relates to the field of cassette roller technology, and in particular to an integrated cassette roller. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] The sintering trolley wheel chuck assembly is a crucial component of the sintering trolley. It is mounted on the wheel axle of the sintering trolley. When the sintering trolley reaches the star wheel position of the sintering machine, the star wheel tooth plate groove engages the wheel chuck, driving the sintering trolley to rotate and move. During production operation, the sintering trolley wheel chuck assembly experiences high operating temperatures, high dust levels, and heavy loads, resulting in significant friction between the sliding elements. This causes severe wear and tear on the bushings and journals, leading to their failure. Seizure can occur between the shaft, bushing, and wheel chuck. When the wheel chuck meshes with the star wheel of the sintering machine, sliding friction occurs, causing wear on the star wheel tooth plate, increased drive current, and trolley misalignment, posing significant challenges to production and maintenance.

[0004] The prior art discloses an integrated roller chuck, utility model patent with announcement number CN211601562U. It discloses a structure consisting of a wheel axle, a trolley body, a wheel body, a retaining ring, and a connecting block. The retaining ring separates the wheel axle, thereby preventing direct contact and sliding of the wheel axle, effectively avoiding wear and increasing the service life of the wheel axle. However, the above-mentioned technical solutions and related technologies still have many problems, such as: during the turning process of the sintering trolley, the rotation speed of the outer wheel is inconsistent with that of the inner wheel, and the sintering trolley is still prone to deviation. In addition, long-term wear can easily lead to increased friction between the various components of the chuck, resulting in noise or poor movement. Utility Model Content

[0037] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0038] This utility model is mainly an improvement to address the problems in the prior art where the roller is prone to deviation when turning due to the inconsistent rotation speeds of the inner and outer ends, and the abnormal noise or severe wear caused by the large friction between the inner and outer rings 100. The specific improvement scheme is shown in the following embodiments.

[0039] Example 1

[0040] Participate in the attached Figure 1-3 An integrated chuck wheel includes: an outer ring 100 having a through-hole; and an inner ring including an inner ring a200 and an inner ring b300, both of which are rotatably mounted in the inner hole of the outer ring 100 and are rotatably mounted relative to the outer ring 100 via rollers 500. The inner rings a200 and b300 are rotatably mounted relative to each other, and the contact surfaces of the inner rings a200 and b300 are configured for plug-in mounting. The inner ring a200 has a protrusion, and the inner ring b300 has a groove that mates with the protrusion. It can be understood here that both inner ring a200 and inner ring b300 are rotatably mounted relative to outer ring 100, and simultaneously, inner ring a200 and inner ring b300 are also rotatably mounted relative to each other. That is, inner ring a200 and inner ring b300 can rotate relative to outer ring 100 at different speeds. The outer ring 100 is provided with a lubrication oil passage along the radial direction. This oil passage is used to inject lubricating oil to lubricate the roller 500. The purpose of setting up the lubrication oil passage here is to lubricate the roller 500. On the one hand, it can cool down the high-speed rotating roller 500. On the other hand, it can reduce the friction between the roller 500 and inner ring a200, inner ring b300 and outer ring 100, and prevent abnormal noise or wear damage.

[0041] Specifically, participate in the attached Figure 3Sealing elements are installed between the inner ring a200 and the inner ring b300 and the inner hole of the outer ring 100 to seal the lubricating oil entering the mounting cavity of the roller 500 through the lubrication oil passage. The sealing ring 600 is made of fluororubber. The outer circumferential surface of the inner ring a200 and the inner ring b300 is provided with a radially recessed sealing mounting groove. The sealing element is an O-ring 600. The O-ring 600 is installed in the sealing mounting groove and is pressed and sealed with the inner hole of the outer ring 100. The O-ring 600 is located on one side of the roller 500 and close to both ends of the outer ring 100. The purpose of the sealing ring 600 is to effectively prevent the lubricating oil in the oil cavity 102 from leaking along the gap between the inner ring a200 or the inner ring b300 and the outer ring 100 once it enters the area around the roller 500, thus maintaining a good working environment for the wheel during operation.

[0042] Specifically, participate in the attached Figure 3 The lubrication circuit includes an oil injection hole 101 radially disposed on an outer ring 100 and an oil cavity 102. The oil cavity 102 is a sealed cavity formed by the inner hole of the outer ring 100, an inner ring a200, an inner ring b300, and rollers 500 between the inner rings a200 and b300 and the outer ring 100. A sealing plug 400 is installed at the inlet of the oil injection hole 101 on the outer ring 100. The number of oil injection holes 101 is at least one. It can be understood that the oil injection hole 101 is a cylindrical through hole that penetrates radially along the outer ring 100. The sealing plug 400 is installed at the outer end of the oil injection hole 101, and the inner end of the oil injection hole 101 is connected to the oil cavity 102. The oil cavity 102 is connected to the mounting cavities of the rollers 500 at both ends.

[0043] When the roller of this utility model is working, an axle is installed on the inner ring a200 and the inner ring b300 respectively. Since the inner ring a200 and the inner ring b300 are installed in relative rotation, the axles of the inner ring a200 and the inner ring b300 can be installed in relative rotation. At the same time, lubricating oil can be introduced through the oil injection hole 101. The lubricating oil enters the oil chamber 102 through the oil injection hole 101 and then lubricates the roller 500, thereby achieving noiseless operation.

[0044] Example 2

[0045] Participate in the attached Figure 4-7 Based on Embodiment 1, a shrinkage hole 1011 with a size smaller than the inner diameter of the oil injection hole 101 is provided between the oil injection hole 101 and the oil cavity 102. A ball bearing 700 is installed between the outlet of the shrinkage hole 1011 and the contact surface of the inner ring a200 and the inner ring b300. The outlet of the shrinkage hole 1011 is provided with a concave hole that matches the arc surface of the ball bearing 700. The end faces of the inner ring a200 and the inner ring b300 are both provided with grooves to form a chamfer tangent to the arc surface of the ball bearing 700. The two chamfers together form an annular groove with a triangular cross section.

[0046] Alternatively, the following method can be used: a shrinkage hole 1011 with a size smaller than the inner diameter of the oil injection hole 101 is provided between the oil injection hole 101 and the oil cavity 102. A ball bearing 700 is installed between the outlet of the shrinkage hole 1011 and the contact surface of the inner ring a200 and the inner ring b300. An annular groove matching the arc surface of the ball bearing 700 is provided at the outlet of the shrinkage hole 1011. The end faces of the inner ring a200 and the inner ring b300 are both provided with grooves to form a chamfer tangent to the arc surface of the ball bearing 700. The two chamfers together form an annular groove with a triangular cross section.

[0047] Alternatively, the following method can be used: a shrinkage hole 1011 with a size smaller than the inner diameter of the oil injection hole 101 is provided between the oil injection hole 101 and the oil cavity 102. A ball bearing 700 is installed between the outlet of the shrinkage hole 1011 and the contact surface of the inner ring a200 and the inner ring b300. An annular groove tangent to the arc surface of the ball bearing 700 is provided at the outlet of the shrinkage hole 1011. The end faces of the inner ring a200 and the inner ring b300 are both provided with grooves to form a chamfer tangent to the arc surface of the ball bearing 700. The two chamfers together form an annular groove with a triangular cross section.

[0048] In all the above scenarios, it is understood that the number of balls 700 is at least one, preferably three, and the shape of the constriction orifice 1011 is funnel-shaped. When the outlet of the constriction orifice 1011 is provided with a concave hole that matches the arc surface of the ball 700, the relative position of the ball 700 and the outer ring 100 remains unchanged, but the ball 700 and the outer ring 100 rotate relative to each other. When the outlet of the constriction orifice 1011 is provided with an annular groove that matches the arc surface of the ball 700, the ball 700 can rotate and slide within the annular groove. When the outlet of the constriction orifice 1011 is provided with an annular groove that is tangent to the arc surface of the ball 700, the ball 700 can rotate and slide within the annular groove.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
