Technical Field

[0001] The utility model relates to the technical field of bearing assembly, in particular to an assembly support frame for a wind power spherical roller bearing. Background Art

[0002] Spherical roller bearings are a type of rolling bearings that rely on rolling contact between main components to support rotating parts. Spherical roller bearings are now mostly standardized and have the advantages of high rotation accuracy and easy selection.

[0003] The four major components of traditional wind power spherical roller bearings, namely the inner ring, outer ring, cage and rolling element, are manufactured and inspected to be qualified before entering the finished product workshop for assembly. The inner components of the bearing and the outer sleeve must be qualified before assembly. Spherical roller bearings are large in size, and large or extra-large wind power spherical roller bearings are currently assembled on site. Two operators are required to hold the outer ring steady from both sides, and one operator is required to install the rollers. This assembly method is not only inefficient but also has a low safety factor, and the quality is not guaranteed. Utility Model Content

[0004] In view of the defects of the prior art, the utility model provides a wind power spherical roller bearing assembly support frame, which does not require an operator to manually position the outer ring, saves manpower, improves stability, and thus can improve assembly efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is a wind power spherical roller bearing assembly support frame, which includes a base, two support rollers, a first support rod and a second support rod. The two support rollers are both rotatably connected to the base in a first direction. The two support rollers are parallel to each other, and a limiting groove is formed between the two. The limiting groove is used to support the outer diameter of the outer ring; the first support rod is arranged on the base and is located on the symmetric center line of the two support rollers, supporting the end face of one side of the inner ring in the second direction; the second support rod is arranged on the base and is located on the symmetric center line of the two support rollers, supporting the end face of the other side of the inner ring in the second direction; the first direction is perpendicular to the second direction. During assembly, the outer ring is perpendicular to the inner ring, and the retaining frame is limited to between the inner ring and the outer ring.

[0006] Furthermore, the first support rod is vertically fixed to the base, and the second support rod is vertically abutted between the base and the end surface of the inner ring.

[0007] Furthermore, the second support rod is a T-shaped support workpiece.

[0008] Furthermore, the first support rod and the second support rod are both rotatably connected to the base to have a supporting state and a folding state.

[0009] Furthermore, the base is provided with a first accommodating groove and a second accommodating groove, which are used to accommodate at least a portion of the first supporting rod and at least a portion of the second supporting rod respectively.

[0010] Furthermore, anti-slip sleeves are provided on the ends of the first support rod and the second support rod away from the base.

[0011] Furthermore, outer surfaces of the two supporting rollers are covered with protective covers.

[0012] Furthermore, the two supporting rollers are connected to the base via bearings.

[0013] Furthermore, the first direction is a horizontal direction, and the second direction is a vertical direction.

[0014] The beneficial effects of the utility model are as follows: two support rollers are provided, and a limited position groove is formed between the support rollers which are parallel to each other. During assembly, the outer ring of the bearing can be tangent to and abut against the two support rollers, so that the outer ring stands between the two support rollers, and the operator does not need to manually position the outer ring, which saves manpower, improves stability, and thus improves assembly efficiency. In addition, the two support rollers support the outer ring from both sides, which can improve the stability of the outer ring positioning, avoid the outer ring from tilting to a certain extent, and improve the safety factor of assembly.

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] See also Figure 1 and Figure 2 , shows a wind power spherical roller bearing assembly support frame in one embodiment of the utility model, which includes a base 100, two support rollers 200, a first support rod 300 and a second support rod 400. Both support rollers 200 are rotatably connected to the base 100 in the first direction, and the two support rollers 200 are parallel to each other, and a limiting groove a is formed between the two, and the limiting groove a is used to support the outer diameter of the outer ring 1; the first support rod 300 is arranged on the base 100 and located on the symmetric center line of the two support rollers 200, and supports the end face of one side of the inner ring 2 in the second direction; the second support rod 400 is arranged on the base 100 and located on the symmetric center line of the two support rollers 200, and supports the end face of the other side of the inner ring 2 in the second direction; the first direction is perpendicular to the second direction, and when assembled, the outer ring 1 is perpendicular to the inner ring 2, and the retaining frame 3 is limited between the inner ring 2 and the outer ring 1.

[0029] See also Figure 1 and Figure 5During assembly, first place the outer ring 1 on the limiting groove a between the two support rollers 200. The support roller 200 is tangent to and abuts against the outer ring 1 of the bearing. Assemble the inner ring 2 and the retainer 3 and place them on the inner side of the positioned outer ring 1. Rotate the retainer 3 and load the rolling bodies one by one from the lower ball loading port b of the inner ring 1. Continue to rotate the retainer 3 to complete the assembly of the lower rolling bodies. When installing the upper rolling bodies, adjust the inner ring 2 to be perpendicular to the outer ring 1. Support the first support rod 300 and the second support rod 400 below the end face of the inner ring 2. The lower rolling bodies that have been installed limit the retainer 3. Rotate the retainer 3 and load the rolling bodies one by one from the upper ball loading port c of the inner ring 1 to complete the assembly of the rolling bodies.

[0030] The above-mentioned wind power spherical roller bearing assembly support frame is provided with two support rollers 200, and a limited position groove a is formed between the mutually parallel support rollers 200. During assembly, the outer ring 1 of the bearing can be tangent to and abut against the two support rollers 200, so that the outer ring 1 stands between the two support rollers 200, and there is no need for the operator to manually position the outer ring 1, which saves manpower and can improve the assembly efficiency. In addition, the two support rollers 200 support the outer ring 1 from both sides, which can improve the stability of the positioning of the outer ring 1, avoid the tilt of the outer ring 1 to a certain extent, and improve the safety factor of assembly. In this way, the bearing can be not only radially fixed but also axially fixed during assembly, which improves the quality coefficient, and the better quality of the bearing after assembly can also extend the service life to a certain extent.

[0031] like Figure 1-Figure 3 As shown, in one embodiment, the first support rod 300 is vertically fixed to the base 100, and the second support rod 400 is vertically abutted between the base and the end surface of the inner ring 2. In the specific setting, in one embodiment, the second support rod 400 is a T-shaped support workpiece. In this embodiment, the first support rod 300 can be detachably installed on the base 100, and the second support rod 400 is independently set, and existing tools at the construction site, such as a hammer, etc., can be used.

[0032] See also Figure 4-Figure 6 In another embodiment, the first support rod 300 and the second support rod 400 are both rotatably connected to the base 100 to have a supporting state and a folding state.

[0033] Preferably, further, in one embodiment, the base 100 is provided with a first receiving groove 110 and a second receiving groove 120, which are respectively used to accommodate at least part of the first support rod 300 and at least part of the second support rod 400. When not in use, the first support rod 300 and the second support rod 400 can be folded and accommodated in the first receiving groove 110 and the second receiving groove 120 for storage, which saves more space. When in use, it is only necessary to rotate the first support rod 300 and the second support rod 400 so that they are perpendicular to the base 100, which is more convenient and labor-saving to operate. Compared with the solution of separately setting the second support rod 400, it can also prevent the second support rod 400 from being lost.

[0034] In one embodiment, the ends of the first support rod 300 and the second support rod 400 away from the base 100 are covered with anti-skid sleeves, namely, the first anti-skid sleeve 310 and the second anti-skid sleeve 410. Such a configuration can prevent the first support rod 300 and the second support rod 400 from easily detaching from the end surface of the inner ring 2, thereby improving the reliability of the device.

[0035] See also Figure 1 and Figure 2 In one embodiment, the outer surfaces of the two support rollers 200 are covered with protective sleeves 210. In this embodiment, the protective sleeve 210 can provide a certain degree of protection for the outer ring 1 to avoid scratching the outer ring 1. In one embodiment, the two support rollers 200 are connected to the base 100 through bearings. It should be noted that in addition to the above-mentioned setting method, other methods can also be used to rotatably connect the two support rollers 200.
