BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a physical picture of the prior art;
[0013] Figure 2 It is a physical diagram of the utility model;
[0014] Figure 3 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0015] The present invention will be further described below by way of embodiments, but the scope of the present invention is not limited thereto.
[0016] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0017] like Figure 2-3 As shown, a side vertical roller of a roller table comprises an oil drum 1 with a closed bottom and an open top, a shaft 2 is installed in the oil drum, the shaft and the oil drum are axially fixed and circumferentially rotatably matched, a vertical roller 3 is fixedly installed on the upper end of the shaft, a waterproof cover 4 is fixedly installed on the shaft, and the waterproof cover covers the oil drum with a gap between the waterproof cover and the oil drum.
[0018] Among them, the shaft has a first step and a second step. Specifically, the shaft includes at least a first section shaft, a second section shaft, and a third section shaft from bottom to top. The diameter of the second section shaft must be larger than the diameters of the first section shaft and the third section shaft, thereby forming the first step and the second step.
[0019] There is a third step at the bottom of the oil barrel, the first step is pressed on the inner ring of the first bearing 5, the outer ring of the first bearing is pressed on the third step, the inner ring of the second bearing 6 is pressed on the second step, the pressure cover 7 is sleeved on the shaft and pressed on the outer ring of the second bearing, the pressure cover is rotatably matched with the shaft, and the pressure cover is fixedly connected to the oil barrel by a plugging screw 8.
[0020] By arranging the first step, the second step, the pressure cover on the shaft, and the third step at the bottom of the oil drum, when installing the first and second bearings, the first and second bearings are placed in corresponding positions, the first bearing is clamped between the oil drum and the shaft by the shaft, and the second bearing is clamped between the shaft and the pressure cover by the pressure cover, no other connection method is required, and disassembly and assembly are more convenient.
[0021] Among them, the first bearing and the second bearing can be plane bearings, tapered roller bearings, thrust ball bearings, etc.
[0022] When the second bearing adopts a plane bearing or a tapered roller bearing, the gland needs to be pressed on the outer ring, and ribs / protrusions are provided on the lower surface of the gland corresponding to the outer ring to prevent the gland from pressing on the inner ring.
[0023] The shaft and the vertical roller are connected by keys.
[0024] The waterproof cover is sleeved on the shaft and covers the oil barrel, and the waterproof cover and the shaft are fixedly connected by a pin.
[0025] The waterproof cover has a flange 41 on its circumference, and the height of the lower end surface of the flange is lower than the height of the upper edge of the oil drum.
[0026] The flange design can prevent dust and other debris from entering the oil barrel. There is a gap between the flange and the oil barrel, so there is no friction between the flange and the oil barrel when the shaft rotates.
[0027] It also includes a spacer sleeve 9, the lower end of which is pressed on the pressure cover, and the upper end of which is pressed against the waterproof cover through a retaining spring 10, and the upper end of the waterproof cover is pressed against the vertical roller.
