Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1 to 2, a quick dismounting device for a self-aligning roller bearing according to a preferred embodiment of the present invention includes at least two support plates 1, 1 ', first press plates 2, 2 ', second press plates 3, 3 ', a jack 6, two hook plates 4, and two pins 5.
Referring to fig. 1 and 2, in some embodiments, at least two support plates 1, 1' are symmetrically disposed at the edge of the bearing hole of the bearing housing 9. The first pressure plate 2, 2 'is arranged on at least two support plates 1, 1', the first pressure plate 2, 2 'comprising two first hook holes 21, 21'. The second pressure plate 3, 3 'is arranged above the first pressure plate 2, 2', the second pressure plate 3, 3 'comprising two second hook holes 31, 31'. The jack 6 is arranged between the first press plate 2, 2 'and the second press plate 3, 3'. The upper end of each hook plate 4 is provided with a pin hole 42, and the lower end is provided with a bottom hook 41. The two hook plates 4 respectively pass through the first hook plate holes 21 and 21 ' and the second hook plate holes 31 and 31 ', meanwhile, the two pins 5 are inserted into the pin holes 42, the pins 5 are arranged on the edges of the two sides of the width of the second hook plate holes 31 and 31 ', and the bottom hook 41 is hooked to the edge of the inner hole of the bearing outer ring 7.
As shown in fig. 2-5, in some embodiments, the first and second platens 2, 2 ', 3' may be circular or rectangular in shape. The outer edge of the first press plate 2, 2 'and the second press plate 3, 3' is larger than the diameter of the bearing hole of the bearing seat 9, because the two support plates 1, 1 'are symmetrically arranged at the edge of the bearing hole of the bearing seat 9, so the size of the first press plate 2, 2' needs to be slightly larger than the diameter of the bearing hole. The supporting plates 1 and 1' are not limited to two, but may be increased to three or four, so that the force is more uniform.
In some embodiments, the support plate 1, 1' is shaped as a straight plate or an arc-shaped bent plate. The distance between the two support plates 1, 1' is greater than the diameter of the bearing bore of the bearing block 9. The supporting plates 1, 1 'of the present embodiment are connected to the first pressing plates 2, 2', and the connection manner can be, but is not limited to, welding. The height of the support plate 1, 1 'should be at least greater than the depth of the bearing bore of the bearing seat 9, i.e. the space between the first pressure plate 2, 2' and the end face of the bearing bore should be able to accommodate the entire bearing outer ring 7.
In some embodiments, the first hook plate hole 21, 21 'and the second hook plate hole 31, 31' are in the shape of circular holes, oblong holes, straight oblong holes, or arc-shaped oblong holes. The distance between the two first hook holes 21 and 21 'and the two second hook holes 31 and 31' is matched with the diameter of the inner hole of the bearing outer ring 7. Since the two hook plates 4 pass through the two first hook plate holes 21, 21 'and the two second hook plate holes 31, 31' and then hook the inner control edge of the bearing outer ring 7 with the bottom hook 41 from the inner hole of the bearing outer ring 7, the distance between the two first hook plate holes 21, 21 'and the two second hook plate holes 31, 31' must satisfy the above condition.
As shown in fig. 6, in some embodiments, the width of the upper end of the hook plate 4 is greater than the width of the middle part of the hook plate 4 and the width of the bottom hook 41, which is designed because the end part must be provided with a pin hole 42, and the pin hole 42 is the main stressed part of the device and is necessary for ensuring the bearing strength. The width of the two first hook holes 21, 21 'and the two second hook holes 31, 31' is greater than the length of the bottom hook 41, which is a requirement to enable the bottom hook 41 to pass through the first hook holes 21, 21 'and the second hook holes 31, 31'. The length of pin 5 is greater than the width of the two first hook holes 21, 21 'and the two second hook holes 31, 31' because pin 5 must be on the upper surface of second press plate 3, 3 'beyond the width of second hook holes 31, 31'.
In some embodiments, the above parts of the quick dismounting device for a self-aligning roller bearing of the present invention may be made of steel plates.
The use method of the quick dismounting device of the self-aligning roller bearing comprises the following steps:
first, the fan shaft and the fan are removed from the inner hole of the bearing rolling member 8 (the fan shaft and the inner hole of the bearing rolling member 8 are in clearance fit), and the center line of the bearing rolling member 8 is adjusted to be perpendicular to the axis line of the bearing hole. The supporting plates 1 and 1 ' and the first pressing plates 2 and 2 ' are arranged, the supporting plates 1 and 1 ' are placed at the edge of one end of a bearing hole of the bearing seat 9, and the two first hook plate holes 21 and 21 ' on the first pressing plates 2 and 2 ' are aligned with gaps on two sides of the bearing rolling body 8 below the first pressing plates. The jack 6 is placed at the center of the first pressing plates 2 and 2 ', the second pressing plates 3 and 3' are pressed on the jack 6, and the second hook plate holes 31 and 31 'are aligned with the first hook plate holes 21 and 21' below the second hook plate holes. After the hook plate 4 passes through the second hook plate holes 31, 31 'and the first hook plate holes 21, 21', the bottom hook 41 is slightly lower than the bottom edge of the inner hole of the bearing outer ring 7, and the upper end of the pin 5 is inserted into the pin hole 42, the two ends of the pin 5 are supported on the upper surfaces of the second pressing plates 3, 3 'on both sides of the width of the first hook plate holes 21, 21'. The jack 6 is slowly started to slowly lift the second pressing plates 3 and 3' and the hook plate 4 until the bottom hook 41 hooks the lower edge of the inner hole of the bearing outer ring 7 (in order to avoid direct contact between the bottom hook 41 and the bearing outer ring 7, a non-metal gasket can be arranged at the contact surface). And then, the jack 6 is continuously started until the bearing outer ring 7 is completely pulled out from the bearing hole of the bearing seat 9, and the disassembly is completed.
In summary, the quick dismounting device for the self-aligning roller bearing has the following beneficial effects: it sets up backup pad, first clamp plate, second clamp plate, jack, colludes board and pin through the one end at the dead eye of bearing frame, supports the second clamp plate through the jack, and the second clamp plate drives through the pin and colludes board and end hook removal, can convenient and fast dismantles aligning roller bearing, and the bearing is not fragile moreover. And the quick dismounting device can be directly welded and manufactured by steel plates, is simple to manufacture and low in cost, and can be suitable for dismounting the self-aligning roller bearings of various models within a certain size.
