Technical Field
[0001] The utility model relates to the technical field of ductile iron bearing seats, in particular to a high-load ductile iron bearing seat. Background Art
[0002] The bearing seat, also known as the bearing seat unit, is a collection of bearings and housings. Its main function is to support the outer ring of the bearing, fix the bearing position, and allow the inner ring of the bearing to rotate freely, while the outer ring remains relatively still and consistent with the transmission direction. Among them, the ductile iron bearing seat is made of ductile iron. Compared with traditional bearing seats, it is lighter and thinner, but the strength is much improved. It has the characteristics of high corrosion resistance and high load. However, when in use, a part of the bearing is exposed in the bearing seat, which is easy to enter with foreign matter. The entry of foreign matter will affect the use of the bearing, and there are certain shortcomings. For this reason, we have proposed a high-load ductile iron bearing seat. Utility Model Content

[0010] By adopting the above technical scheme, the beneficial effects achieved by the utility model are as follows: the utility model realizes the dustproof effect of the bearing without affecting the use of the bearing seat by arranging the dustproof tube, the dustproof assembly and the fasteners, thereby preventing foreign matter from entering the bearing and affecting the use. At the same time, the fixing effect of the bearing can be improved by arranging the dustproof assembly to prevent the bearing from separating from the bearing seat. When in use, the user can insert the upper dustproof shell and the lower dustproof shell of the dustproof assembly into the annular groove, and then loosen the bolts of the fasteners, rotate the rotating plate after loosening, until the rotating plate blocks the gaskets on the upper dustproof shell and the lower dustproof shell, and then tighten the bolts to fix the dustproof assembly. After fixing, the dustproof assembly and the dustproof tube can increase the difficulty of foreign matter entering the bearing, thereby achieving the dustproof effect.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0024] Some embodiments of the utility model are described below in conjunction with the accompanying drawings to provide a high-load ductile iron bearing seat.
[0025] Embodiment 1:
[0026] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a high-load ductile iron bearing seat, including a bearing seat body 100, a tightening knob 200, a dustproof tube 300, a dustproof assembly 400 and a fastener 500.
[0027] Specifically, the bearing seat body 100 includes a seat body 101 and an annular groove 104 opened on the right side of the seat body 101. The top and bottom of the seat body 101 are respectively provided with an upper mounting plate 102 and a lower mounting plate 103. The upper mounting plate 102 and the lower mounting plate 103 have the same structure. The upper mounting plate 102 and the lower mounting plate 103 can be fixed by bolts. When one of the upper mounting plate 102 and the lower mounting plate 103 is severely worn, it can be replaced for use.
[0028] Specifically, the tightening knob 200 is threadedly connected to the seat body 101 , and the tightening knob 200 can be rotated to press against the bearing so as to fix the bearing on the seat body 101 .
[0029] Specifically, the dustproof tube 300 is arranged on the left side of the seat body 101 , and the dustproof tube 300 can increase the difficulty of foreign matter entering the bearing, thereby achieving a dustproof effect.
[0030] Specifically, the dustproof assembly 400 includes an upper dustproof shell 401 inserted in the annular groove 104, a lower dustproof shell 402 inserted in the annular groove 104, and a gasket 403 arranged on the outside of the upper dustproof shell 401 and the lower dustproof shell 402. The upper dustproof shell 401 has the same structure as the lower dustproof shell 402. The bottom of the upper dustproof shell 401 is abutted and connected with the lower dustproof shell 402. The upper dustproof shell 401 and the lower dustproof shell 402 are inserted in the annular groove 104. After the insertion, the upper dustproof shell 401 and the lower dustproof shell 402 abut. After the abutment, the difficulty of foreign matter entering the bearing can be increased through the upper dustproof shell 401 and the lower dustproof shell 402, thereby achieving a dustproof effect. At the same time, the bearing can be blocked to prevent the bearing from detaching from the seat body 101 for use.
[0031] Specifically, the fastener 500 includes a fixing seat 501 arranged on the right side of the seat body 101, a fixing bolt 502 threadedly connected to the fixing seat 501, and a rotating plate 503 rotatably connected to the fixing bolt 502. A rotating hole is opened on the rotating plate 503. Two fasteners 500 are arranged, and the two fasteners 500 are symmetrically arranged on the right side of the seat body 101. The fixing bolt 502 can be loosened. After loosening, the rotating plate 503 can be rotated to block the gasket 403 on the upper dustproof shell 401 and the lower dustproof shell 402. After blocking, the fixing bolt 502 can be tightened to fix the upper dustproof shell 401 and the lower dustproof shell 402.
[0032] Embodiment 2:
[0033] Reference Figure 1 and Figure 5 , which is the second embodiment of the utility model, which is different from the first embodiment in that it also includes a sealing cover 600, and a slide groove 601 is provided on the outer side of the sealing cover 600. The sealing cover 600 is slidably connected with the base body 101 through the slide groove 601. The top and bottom ends of the sealing cover 600 are both provided with grooves 602. After the upper mounting plate 102 or the lower mounting plate 103 is fixed by bolts, the sealing cover 600 can be moved up and down until the sealing cover 600 completely covers the bolts fixing the upper mounting plate 102 or the lower mounting plate 103, thereby preventing external dust and water from contacting the bolts to accelerate corrosion and extend the service life.
[0034] The working principle and use process of the utility model are as follows: when in use, first insert the bearing into the seat body 101, and then rotate the tightening knob 200 until the tightening knob 200 abuts against the bearing to fix the bearing, and then insert the upper dustproof shell 401 and the lower dustproof shell 402 of the dustproof assembly 400 into the annular groove 104, and then loosen the fixing bolts 502 of the two fasteners 500, and after loosening the fixing bolts 502, rotate the rotating plate 503 until the two rotating plates 503 block the gaskets 403 on the upper dustproof shell 401 and the lower dustproof shell 402, and then tighten the fixing bolts 502 to fix. The dustproof component 400 is fixed. After being fixed, the dustproof component 400 and the dustproof tube 300 can increase the difficulty of foreign matter entering the bearing, thereby achieving a dustproof effect. At the same time, the upper dustproof shell 401 and the lower dustproof shell 402 can prevent the bearing from separating from the seat body 101 for use. Subsequently, the upper mounting plate 102 or the lower mounting plate 103 can be fixed by bolts. After fixing, the sealing cover 600 is moved up and down until the sealing cover 600 completely covers the bolts fixing the upper mounting plate 102 or the lower mounting plate 103, thereby preventing external dust and water from contacting the bolts to accelerate corrosion and extend the service life.
[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
