Technical Field

[0001] The utility model relates to the technical field of generator shaft system assembly, and more specifically to a generator shaft system assembly auxiliary device. Background Art

[0002] The bearing is an important component in the generator shaft system. Its main function is to support the rotation of the generator shaft, reduce friction and wear, and also bear the weight and rotational torque of the shaft. Its important function is to reduce energy loss, thereby improving the efficiency and life of the generator. The bearing seat is the support structure for mounting the bearing on the generator housing, and the bearing and the bearing seat have an interference fit.

[0003] At present, when assembling the bearing and the bearing seat, the operator first places the bearing on the support fixture and levels it, then heats the bearing to achieve the expansion amount that meets the process requirements, lifts the bearing seat and slowly drops it, and at the same time, the operator visually confirms whether the bearing seat and the bearing are concentric, and then assembles them after they are concentric. However, if the bearing seat and the bearing are assembled in the above manner for a long time, the operator is prone to visual fatigue, which may cause the bearing and the bearing seat to be non-concentric during assembly, which may easily cause the bearing to get stuck, and the bearing and the bearing seat to lock and be difficult to disassemble; in addition, the operator constantly adjusts the bearing seat visually to make the bearing seat and the bearing concentric, which takes a long time to assemble, and the inner diameter of the bearing seat will become smaller due to heat loss, making it impossible to assemble the bearing in place.

[0004] In summary, how to solve the current problem of difficulty in confirming the concentricity of the bearing and the bearing seat during assembly, as well as the low assembly efficiency, is an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a generator shaft system assembly auxiliary device, which effectively ensures the concentric assembly of the bearing and the bearing seat and improves the assembly efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, the limiting structure is an annular retaining ring, which is used to be sleeved on the outer periphery of the bearing.

[0009] Preferably, the limiting structure is a limiting block, and there are at least two limiting blocks, and the heights of at least two limiting blocks are consistent and evenly distributed on the top end surface of the support seat.

[0010] Preferably, the limiting structure is made of rubber.

[0011] Preferably, the outer side wall of the support seat is provided with a plurality of mounting grooves distributed along its circumference, the plurality of mounting grooves correspond one-to-one to the plurality of direct-light lamps, and each of the mounting grooves is used for installing a bracket for inserting the direct-light lamp.

[0013] Preferably, the interior of the support seat is a hollow structure.

[0014] Compared with the above-mentioned background technology, when the generator shaft system assembly auxiliary device provided by the utility model is applied to the assembly operation of the bearing and the bearing seat, the support seat is horizontally fixed on the ground, the bearing is fixed on the top of the support seat and leveled, and then a plurality of direct-shooting lamps are evenly arranged on the outer wall of the support seat around the circumference of the support seat, and the light of each direct-shooting lamp is projected vertically upward, and the horizontal position of the plurality of direct-shooting lamps is adjusted according to the outer circumference of the bearing, that is, the direct-shooting lamps are moved along the radial direction of the bearing seat, so that the light of each direct-shooting lamp is aimed at the outer circumference of the bearing, and the diameter of the bearing is projected 1:1 onto the suspended bearing seat, so that the operator can confirm that the bearing seat is concentric with the bearing, and at the same time, the bearing seat slowly falls to complete the assembly of the bearing seat and the bearing. Therefore, the present application uses a plurality of direct-shooting lamps to assist the operator in confirming whether the bearing and the bearing seat are concentric, so as to avoid the poor accuracy of the concentric assembly of the bearing and the bearing seat due to manual visual inspection, thereby effectively ensuring the concentric assembly of the bearing and the bearing seat, and avoiding the operator from repeatedly confirming whether the bearing and the bearing seat are concentric, thereby improving the assembly efficiency of the bearing and the bearing seat.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The core of the utility model is to provide a generator shaft system assembly auxiliary device, which effectively ensures the concentric assembly of the bearing and the bearing seat and improves the assembly efficiency.

[0022] It should be noted that in the present embodiment, the orientation or position relationship indicated by "upper", "lower", etc. is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0023] Please refer to Figure 1 The present application provides a generator shaft assembly auxiliary device, including a support seat 1 and a plurality of direct-projection lamps 2. A limiting structure 3 is provided at the top of the support seat 1 for fixing a bearing 4. The bottom end of the support seat 1 is used to be horizontally fixed on the ground. The plurality of direct-projection lamps 2 are evenly distributed around the circumference of the support seat 1 and are all movably arranged on the outer wall of the support seat 1 along the radial direction of the support seat 1. The light of each direct-projection lamp 2 is parallel to the axial direction of the support seat 1 and is arranged toward the top of the support seat 1.

[0024] It should be noted that the bottom end of the support seat 1 is used to be fixed on the ground and kept horizontal, so that the axial direction of the support seat 1 is set vertically, and a limiting structure 3 is set at the bottom end of the support seat 1. The limiting structure 3 can fix the bearing 4 and keep the bearing 4 horizontal. The support seat 1 plays a role in supporting and fixing the bearing 4. Multiple direct lamps 2 are evenly distributed around the circumference of the support seat 1. The light of each direct lamp 2 is parallel to the axial direction of the support seat 1 and is set toward the top of the support seat 1, even if the light of each direct lamp 2 is projected vertically upward, and each direct lamp 2 is movably placed on the outer wall of the support seat 1 along the radial direction of the support seat 1, so that the light of each direct lamp 2 is aligned with the outer periphery of the bearing 4.

[0025] When the above structure is applied to the assembly of the bearing 4 and the bearing seat 5, the support seat 1 is fixed horizontally on the ground, the bearing 4 is fixed on the top of the support seat 1 and leveled, and then a plurality of direct-shooting lamps 2 are evenly arranged on the outer wall of the support seat 1 around the circumference of the support seat 1, and the light of each direct-shooting lamp 2 is projected vertically upward, and the horizontal positions of the plurality of direct-shooting lamps 2 are adjusted according to the outer circumference of the bearing 4, that is, the direct-shooting lamps 2 are moved along the radial direction of the bearing seat 5, so that the light of each direct-shooting lamp 2 is aligned with the outer circumference of the bearing 4, and the diameter of the bearing 4 is projected onto the suspended bearing seat 5 at a ratio of 1:1, as shown in FIG. Figure 2 As shown, it is convenient for the operator to confirm that the bearing seat 5 is concentric with the bearing 4, and at the same time, the bearing seat 5 slowly falls down to complete the assembly of the bearing seat 5 and the bearing 4. Therefore, the present application uses multiple direct lights 2 to assist the operator in confirming whether the bearing 4 and the bearing seat 5 are concentric, so as to avoid poor accuracy of the concentric assembly of the bearing 4 and the bearing seat 5 due to human visual inspection, thereby effectively ensuring the concentric assembly of the bearing 4 and the bearing seat 5, and avoiding the operator from repeatedly confirming whether the bearing 4 and the bearing seat 5 are concentric, thereby improving the assembly efficiency of the bearing 4 and the bearing seat 5.

[0026] Considering the specific structure of the limiting structure 3, on the basis of the above embodiment, the limiting structure 3 is an annular retaining ring, which is used to be sleeved on the outer periphery of the bearing 4. Specifically, an annular groove is provided at the top of the bearing seat 5, and an annular retaining ring is provided in the annular groove. The inner diameter of the annular retaining ring is consistent with the outer diameter of the bearing 4. The bearing 4 is placed in the annular retaining ring, and the annular retaining ring can limit the movement of the bearing 4 to play a role in fixing the bearing 4. The limiting structure 3 uses an annular retaining ring, which has low production cost and can reliably fix the bearing 4.

[0027] In addition, the limiting structure 3 can also be a limiting block, and the limiting blocks are set to at least two, and the heights of at least two limiting blocks are consistent and evenly distributed on the top surface of the support seat 1. Specifically, the top surface of the support seat 1 is evenly distributed with at least two limiting blocks, and the heights of each limiting block are equal, so that the bearing 4 can be placed horizontally on at least two limiting blocks, and the movement of the bearing 4 is limited by the friction between the limiting blocks and the support seat 1, so as to play a role in fixing the bearing 4. The limiting structure 3 adopts a limiting block, which has a simple structure and can be adjusted to be placed on the top surface of the bearing seat 5, so as to facilitate the adjustment of the number of limiting blocks and the setting position of the limiting blocks according to the outer diameter size of the bearing 4, so as to be suitable for the limiting of bearings 4 of different specifications and sizes.

[0028] The above-mentioned limiting structure 3 is made of rubber material, that is, the annular retaining ring is a rubber annular retaining ring, or the limiting block is a rubber limiting block, so that the bearing 4 is not in direct contact with the support seat 1. Since the rubber material has good elasticity and energy absorption performance, it can prevent the bearing 4 from deformation and reduce the wear of the bearing 4.

[0029] In one embodiment of a specific connection structure between the direct-projection lamp 2 and the support base 1, the outer wall of the support base 1 is provided with a plurality of mounting grooves distributed along its circumference, the plurality of mounting grooves correspond one-to-one to the plurality of direct-projection lamps 2, and each mounting groove is used to install a bracket for inserting the direct-projection lamp 2.

[0030] Specifically, a plurality of mounting grooves are evenly arranged on the outer side wall of the support base 1, and the number of the mounting grooves is consistent with the number of the direct-light lamps 2. When the direct-light lamp 2 is installed, the direct-light lamp 2 is inserted into the fixing frame at one end of the bracket, and the other end of the bracket is fixed in the mounting groove, so that the direct-light lamp 2 is fixed on the outer side wall of the support base 1. The horizontal position of the direct-light lamp 2 can be adjusted by changing the length of the bracket, so that the light of the direct-light lamp 2 can be aligned with the outer periphery of the bearings 4 of different specifications and sizes, that is, the present application is applicable to the assembly of bearings 4 and bearing seats 5 of different diameters.

[0031] In another embodiment of the specific connection structure between the direct-projection lamp 2 and the support base 1, the outer wall of the support base 1 is provided with a plurality of slide rails distributed along its circumference, the plurality of slide rails correspond one-to-one to the plurality of direct-projection lamps 2, each slide rail is extended radially outwardly along the support base 1, and a slider is provided at the bottom end of each direct-projection lamp 2, which is slidably connected to the slide rail.

[0032] Specifically, multiple slide rails are evenly distributed around the axial direction of the bearing seat 5, and one end of each slide rail is connected to the outer wall of the bearing seat 5, and the other end is extended outward along the radial direction of the bearing seat 5. A slide rail adapted to the slide rail is set at the bottom end of each direct lamp 2, and the direct lamp 2 is slidably set in the slide rail through a slider to facilitate the adjustment of the horizontal position of the direct lamp 2, so that the present application is suitable for the assembly of bearings 4 and bearing seats 5 with different diameters.

[0033] On the basis of the above-mentioned embodiment, the interior of the support base 1 is a hollow structure to reduce the weight of the present application and facilitate adjustment of the installation position.

[0034] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
