Technical Field

[0001] The utility model belongs to the technical field of bearing installers, and more specifically relates to a threaded compression type bearing installer. Background Art

[0002] When installing the bearing, especially when the inner and outer rings are installed at the same time, a double-layer sleeve is often used to press the inner and outer rings of the bearing respectively, and then the knocking method is used for installation.

[0003] This manual tapping installation method usually has the problem of low installation accuracy and bearing damage. When tapping, usually only one point is tapped, which will cause uneven force on the bearing; even if two workers tap at the same time, there will still be uneven force, causing bearing damage.

[0004] Therefore, a device capable of evenly applying force to install bearings is needed to assist workers. Utility Model Content

[0005] The utility model aims to provide a threaded compression type bearing installer to solve the problems of uneven force on the existing bearing installation, laborious installation and easy damage to the bearing in view of the shortcomings of the prior art.

[0021] The utility model provides a threaded compression type bearing installer, which has the following beneficial effects:

[0022] The threaded compression bearing installer uses a tapered sleeve and a sleeve body to be sleeved on the shaft column.

Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0029] like Figure 1 As shown, a threaded compression type bearing installer comprises:

[0030] A sleeve body 1, one end of which is provided with an axial cone;

[0031] A cone sleeve 2, the outer periphery of which is threadedly connected to the cone mouth, one end of the cone sleeve 2 away from the extrusion sleeve 3 is exposed to the sleeve body 1, and a driving part is arranged at the exposed end of the cone sleeve 2;

[0032] The extrusion sleeve 3 has one end which is threadedly connected to the outer periphery of the sleeve body 1 , and the other end of the extrusion sleeve 3 is provided with a push bearing 8 .

[0033] Specifically, the tapered sleeve 2 and the sleeve body 1 are sleeved on the shaft column. When the sleeve body 1 or the tapered sleeve 2 rotates relative to each other, the tapered sleeve 2 locks the shaft column to fix it. Then, the extrusion sleeve 3 rotates relative to the sleeve body 1 to extrude and install the bearing, pushing the bearing 8 to prevent the rotation force of the extrusion sleeve 3 from interfering with the bearing installation, so that the bearing is only subjected to axial force, ensuring that the installation force is uniform and stable.

[0034] Furthermore, the drive bearing can be arranged in a variety of ways. Two bearing rings with the same diameter can be arranged to rotate axially relative to each other; or two bearing rings with concentric centers but different diameters can be arranged to rotate axially relative to each other.

[0035] In this embodiment, a handle is provided at one end of the sleeve body 1 away from the extrusion sleeve 3 , and the handle is used for carrying and rotating the sleeve body 1 .

[0036] Specifically, the handle facilitates installation, carrying and disassembly, and the cone sleeve 2 rotates to keep the sleeve body 1 stationary.

[0037] In this embodiment, the cone sleeve 2 is provided with a driving part, and the driving part is used to drive the cone sleeve 2 to rotate relative to the sleeve body 1.

[0038] Specifically, the driving unit drives the sleeve body 1 to rotate, thereby causing the tapered sleeve 2 to shrink and hold the shaft column tightly.

[0039] In this embodiment, it also includes:

[0040] A rotating motor 4, which is arranged on the outer periphery of the sleeve 1, and a cylindrical driving gear 5 is arranged at the rotating end of the rotating motor 4;

[0042] Specifically, the power is provided by the rotating motor 4, and then the driving gear 5 drives the rotating sleeve to rotate, so that the extrusion sleeve 3 rotates relative to the sleeve body 1, and then extends the extrusion bearing. The columnar driving gear 5 cooperates with the long internal teeth 6 to adapt to the axial displacement movement of the rotating sleeve.

[0043] Furthermore, the rotating motor 4 can be equipped with a battery or directly powered by mains electricity, and a start switch of the rotating motor 4 can be arranged on the handle.

[0044] Furthermore, two handles are symmetrically arranged, and a forward button and a reverse button for controlling the forward and reverse rotation of the rotating motor 4 are respectively arranged on the two handles.

[0046] Specifically, the sealing ring 7 and the baffle cooperate with the outer circumference of the sleeve body 1 to form an annular groove structure, and one end of the rotating sleeve is inserted into the annular groove structure. The annular groove structure prevents the rotating motor 4 or the driving gear 5 from being exposed when the rotating sleeve moves.

[0047] In this embodiment, the sealing ring 7 is detachably connected to the sleeve body 1 .

[0048] Specifically, the detachable connection between the sealing ring 7 and the sleeve body 1 facilitates maintenance of the rotating motor 4 and the driving gear 5 .

[0049] In this embodiment, two annular grooves are arranged on the outer circumference of the sleeve body 1, and the rotary motor 4 and the driving gear 5 are arranged in the two annular grooves respectively.

[0050] Specifically, the rotating motor 4 and the driving gear 5 are positioned respectively by two annular grooves.

[0051] Furthermore, the annular groove is convexly arranged with the sleeve body 1 to improve the structural stability of the sleeve body 1.

[0052] In this embodiment, the driving portion includes a blind hole or a boss.

[0053] Specifically, the cone sleeve 2 is rotated by means of a driving rod through the blind hole or the boss.

[0054] In this embodiment, a plurality of rotating motors 4 are distributed around the outer circumference of the casing 1 .

[0055] Specifically, the rotating sleeve is synchronously driven to rotate by a plurality of rotating motors 4 .

[0056] In this embodiment, the rotary motor 4 is connected to the driving gear 5 via a coupling or a ratchet mechanism.

[0057] Specifically, the coupling is used to compensate for the angle deviation to ensure the transmission effect, and the ratchet mechanism is used to prevent the rotating motor 4 from being overloaded and burned.

[0058] In this embodiment, a threaded compression bearing installer is used, for example, when a device needs to replace a bearing online due to bearing damage, and other parts of the device cannot be disassembled due to structural or operational limitations, only a part of the shaft end of the shaft column where the bearing is installed is exposed, and the outer ring of the bearing also needs to be installed in the frame of the device at the same time;

[0059] The extrusion sleeve 3 is close to the sleeve body 1, and the cone sleeve 2 is sleeved on the shaft column;

[0060] Rotate the cone sleeve 2 to lock the cone sleeve 2 on the shaft column, and then fix the sleeve body 1 on the shaft column;

[0061] The rotary motor 4 is started to rotate the extrusion sleeve 3, and then the extrusion sleeve 3 axially pushes the bearing 8 to install the inner ring bearing.

[0062] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
