Abstract
Description
Technical Field
[0001] This utility model relates to the field of mounting frame technology, specifically to a rotating base for a rotary rheometer. Background Technology
[0002] Rotational rheometers are core equipment for rheological research and industrial quality control. By controlling the rotational motion of the rotor when it contacts the sample, the stress and strain relationship of the sample under shear action is measured. When the rotational rheometer is working, the rotating base at the bottom keeps rotating. After working for a long time, lubricating oil needs to be added to the rotating base to ensure the lubrication of the bearings inside the rotating base and reduce friction. However, the bearings are encapsulated inside the rotating base, making it inconvenient to add lubricating oil. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a rotating base for a rotary rheometer, which addresses the shortcomings of the prior art.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A rotating base for a rotary rheometer includes a lower mounting base with a bearing mounting hole machined in the center. A bearing is installed in the bearing mounting hole and separated from each other by spacers. A retaining spring is installed above the bearing mounting hole to hold the bearing in place. A rotating shaft is connected to the bearing in the middle, and a rotating mounting plate is connected above the rotating shaft. A felt is placed above the bearing and is arranged in a ring structure around the outside of the rotating shaft. An oil injection channel is machined on the lower mounting base and communicates with the side of the felt. A countersunk hole is machined above the oil injection channel, and a plug screw is installed in the countersunk hole. A clearance hole is machined on the rotating mounting plate at the position corresponding to the countersunk hole.
[0005] Furthermore, an upper bearing and a lower bearing are installed in the bearing mounting hole, a felt is provided above the upper bearing, an oil injection channel is machined in the lower mounting seat, and an annular groove is machined on the side wall of the bearing mounting hole on the side of the felt, and the oil injection channel is connected to the annular groove.
[0006] Furthermore, the upper bearing and the lower bearing are separated by an inner ring spacer and an outer ring spacer. A second felt is provided between the inner ring spacer and the outer ring spacer. An oil injection channel is machined in the lower mounting seat. An annular groove is machined on the side wall of the bearing mounting hole on the side of the second felt. The second oil injection channel is connected to the second annular groove. The outer ring spacer has grooves evenly distributed at the position corresponding to the second annular groove.
[0007] Compared with the prior art, the rotating base of the rotary rheometer of this utility model injects lubricating oil into the felt through the oil injection channel. The felt stores the lubricating oil, which enables the bearing to be continuously lubricated, reduces frictional resistance, and makes the rotary rheometer rotate smoothly.

Detailed Implementation
[0009] The technical solutions in the embodiments of this utility model will be clearly and completely described below.
[0010] like Figure 1 As shown, a rotating base for a rotary rheometer includes a lower mounting base 1 with a bearing mounting hole machined in the middle. A bearing 2 is installed in the bearing mounting hole, and the bearings 2 are separated from each other by spacers. A retaining spring 3 is installed above the bearing mounting hole to block the bearings. A rotating shaft 4 is connected in the middle of the bearings, and a rotating mounting plate 5 is connected above the rotating shaft 4. A felt is placed above the bearing 2, and the felt has an annular structure that fits around the outside of the rotating shaft 4. The felt can store lubricating oil to continuously lubricate the bearings. An oil injection channel is machined on the lower mounting base 1, and the oil injection channel communicates with the side of the felt. Lubricating oil is added to the felt through the oil injection channel. A countersunk hole is machined above the oil injection channel, and a plug screw 6 is installed in the countersunk hole to block the oil injection channel and prevent dust from entering the oil injection channel. A clearance hole 7 is machined on the rotating mounting plate 5 at the position corresponding to the countersunk hole. After the clearance hole 7 is rotated into place, the plug screw 6 can be removed to add lubricating oil to the oil injection channel. This eliminates the need to remove the rotating shaft 4 from the rotating base before adding lubricating oil.
[0011] In this embodiment, an upper bearing and a lower bearing are installed in the bearing mounting hole. A felt 7 is provided above the upper bearing. An oil injection channel 8 is machined in the lower mounting base 1. An annular groove 9 is machined on the side wall of the bearing mounting hole on the side of the felt 7. The oil injection channel 8 communicates with the annular groove 9. Lubricating oil is added through the oil injection channel 8. After the lubricating oil passes through the annular groove 9, the felt 7 is soaked in the lubricating oil, and the felt 7 continuously lubricates the upper bearing.
[0012] The upper and lower bearings are separated by an inner ring spacer 10 and an outer ring spacer 11. A second felt 12 is provided between the inner ring spacer 10 and the outer ring spacer 11. An oil injection channel 13 is machined in the lower mounting seat. An annular groove 14 is machined on the side wall of the bearing mounting hole on the side of the second felt 12. The oil injection channel 13 communicates with the annular groove 14. The outer ring spacer 11 has slots 15 evenly distributed at the position corresponding to the annular groove 14. Lubricating oil is added through the oil injection channel 13. The lubricating oil passes through the annular groove 14 and then flows into the second felt 12 from the slots 15 of the outer ring spacer 11, so that the second felt 12 is wetted with lubricating oil and the second felt 12 continuously lubricates the lower bearing.
[0013] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
