[0001] This application is a divisional application of application number 201810351074.8, filed on April 18, 2018, entitled "Bearing Seat and Seal Actuator Handle". Technical Field

[0002] The present invention generally relates to bearing seat and seal tool sets. More specifically, the present invention relates to a combination of a handle and actuator for a bearing seat and seal actuator set, the combination of which can be detachably coupled together. Background Art

[0003] Bearings, also known as bearing seats, are used in many ball bearing applications to allow relative movement between two objects. A bearing seat includes an outer seat and an inner seat, with a ball bearing located between the outer and inner seats. Ball bearings allow the outer and inner seats (typically in circumferential motion) to move relative to each other by reducing friction. In addition, seals are typically used with bearing races and ball bearings to seal the ball bearings and races, thereby reducing contaminants and retaining lubricants, such as grease. However, bearing races and seals require regular maintenance and / or replacement.

[0004] Bearing race and seal actuator assemblies allow users to install bearing races or seals using simple hand tools. For example, the prior art bearing race and seal actuator assembly depicted in Figures 6 and 7. Prior art tool 600 includes: a handle 605, an actuator 610, and a fastener 615. The handle 605 is inserted into the opening of the actuator 610, and the handle 605 is secured to the actuator 610 using the fastener 615.The actuator 610 can then be used to install the bearing race or seal into the necessary recess or opening.

[0005] Conventional bearing race and seal actuators comprise three separate components: a handle 605, an actuator 610, and a fastener 615, which must be joined together to be fully assembled into the tool 600. These individual components may be lost during use or storage. The user must also connect the fastener 615 to the handle 605 using the external thread of the fastener 615 and the internal thread of the handle 605, and vice versa. This process takes time and sometimes requires separate fastening tools to complete the assembly. The tool may also include a handle 605 that is difficult to grip or may fail when struck by a hammer or other tool during use. Summary of the Invention

[0006] The present invention broadly includes bearing race and seal actuators having a molded grip adapted to accommodate the user's hand, while the cap can be struck by a hammer during use. The actuator may include a groove or other recess that receives a ball-shaped latch of the handle for quick assembly and latches the actuator onto the handle. A beneficial effect of the invention is that it eliminates the need for additional fastener components, allowing for quick and easy assembly, and allows the user to hold the tool while simultaneously including a corresponding cap that can be struck to install a seal or bearing race.

[0007] In particular, in one embodiment, the invention broadly includes a tool comprising: a handle having a grip; a rod extending from the grip; an actuator extending from the rod; and a ball disposed within the actuator and offset outwardly relative to the longitudinal axis of the actuator. The tool also includes a drive disc comprising: a body; an opening defined within the body; and a groove defined within the opening, the groove engaging with the ball to latchably or releasably attach the handle to the drive disc.

[0008] In another embodiment, the invention broadly includes a tool comprising: a grip portion made of a grip portion material; a rod extending from the grip portion and having a rod cross-sectional area; a cap portion disposed adjacent to the grip portion and made of a cap portion material, wherein the cap portion material has higher impact toughness compared to the grip portion material; a actuator extending from the rod and having an actuator cross-sectional area smaller than the rod cross-sectional area; a bevel disposed at an axial end of the actuator; and a ball disposed within the actuator and offset outwardly relative to the longitudinal axis of the actuator. The tool may further include a drive disc having: a body; an edge extending circumferentially from the body; an opening defined within the body; and a groove defined within the opening to engage the ball for lockably or releasably attaching a handle to the drive disc.

[0009] In yet another embodiment, the invention broadly includes a method of assembling a tool, the method comprising: providing a handle having: a grip; a rod extending from the grip; a actuator extending from the rod; and a ball disposed within the actuator and biased outward relative to the longitudinal axis of the actuator; providing a drive disc comprising: a body; an opening defined within the body; and a groove defined within the opening; and releasably coupling the handle to the drive disc by inserting the actuator into the opening, pressing the ball to overcome the bias of the ball, such that the ball engages the groove, to lockably or releasably couple the handle to the drive disc.

[0018] Although the invention allows for many different forms of embodiments, it should be understood that the embodiments of the invention, including preferred practices, are shown in the accompanying drawings and will be described in detail herein. The disclosure herein should be considered as an example of the principles of the invention and not as a limitation of the broad aspects of the invention to the illustrated embodiments. As used herein, the term "invention" is not intended to limit the scope of the claimed invention, but is used only for illustrative purposes to discuss exemplary embodiments of the invention.

[0019] The invention broadly includes bearing seat rings and sealing transmission tools with handles that have both a grip for the user's hand and a cap that can be struck by a hammer during use.The actuator may include a groove or other recess that engages with a ball-shaped latch of the handle, allowing for quick assembly of the handle and the actuator.

[0020] Referring to Figures 1 through 5, one embodiment of the invention broadly includes a tool 100 having a handle 105 and a drive disc 110. The handle 105 may include: a grip 115 adapted to be held by a user's hand during use; and a cap 120 which can be struck by a hammer or other tool to install a bearing race or seal. The handle 105 may also include a rod 125 extending from the grip 115, which serves as the structural basis of the handle 105. The rod 125 leads to an actuator 130 having a spring-biased ball 135, such as a ball-shaped latch. The actuator 130 may include a ramp 137 that allows the drive disc 110 to be more easily assembled onto the actuator 130, allowing the actuator 130 to enter the drive disc 110.

[0021] The drive disc 110 may include a base 140 and an edge 145 that circumferentially surrounds the base 140. An opening 150 may be defined through an axial center of the drive disc 110, and the opening 150 may include a groove 155 or other recess that can accommodate a ball 135 to attach the drive disc 110 to the handle 105.

[0022] The grip 115 may be any structure that can be gripped by a user. For example, the grip 115 may be a polymer or foam sleeve surrounding the rod 125, or it may be a molded plastic part with ridges or textures that allow the user to better grip the handle 105. The grip 115 may include an opening from which a cap 120 protrudes. Compared to the grip portion 115, the cap portion 120 can be made of a more durable, high-toughness material that can absorb impact forces from a hammer or other striking tool when the tool 100 is used. For example, the cap portion 120 can be made of metal, and the grip portion 115 can be made of a polymer or foam that is easier to grip. In some embodiments, but not limited to, the cap portion 120 can be an extension of the rod 125 at its axial end, and the grip portion 115 can cover the rod 125. Moreover, the grip portion 115 can circumferentially surround the rod 125.

[0023] The actuator 130 can be an extension of the rod 125 and can have a smaller cross-sectional area, which is measured along a radial section at the actuator 130 and the rod 125. The actuator 130 may be the connection point between the drive disc 110 and the handle 105, and accordingly, when the drive disc 110 is connected to the handle 105, the rod 125, which has a large cross-sectional area, supports the drive disc 110 by abutting against the base of the drive disc 110. In some embodiments, the length of the actuator 130 is at least the same as the axial length of the opening 150 in the drive disc 110.

[0024] The ball 135 may be a spring-biased ball that operates in a conventional spherical locking manner. For example, the ball 135 may include a spring disposed in a hole below the ball to bias the ball 135 outward and engage the ball 135 with a groove 155. The spring force can maintain the engagement of the ball 135 and the groove 155 to lockably connect the handle 105 to the drive disc 110. However, when the drive disc 110 needs to be removed from the handle 105, the spring force of the ball 135 can be overcome to pull the drive disc 110 away from the handle 105. The ball 135 may be disposed within the actuator 130 and biased outward relative to the longitudinal axis of the actuator 130. Therefore, the handle 105 and the drive disc 110 can be lockably connected together in a simple and quick manner without the need for separate fasteners and additional installation steps. For example, due to the ramp 137, the drive disc 110 can be more easily inserted into the drive unit 130, and then the drive disc 110 can be engaged with the ball 135 by positioning the groove 155 on the ball, and then the drive disc 110 can be latchably connected in place for use.

[0025] The base 140 of the drive disc 110 serves as the structural basis of the drive disc 110. As shown, the base 140 is shaped as a disc with an opening 150 defined within the axial center of the disc. Compared to the base 140, the edge 145 can provide different radial circular components around the base 140. For example, as shown in FIG4, the drive disc 110 can be latchably connected to the handle 105 such that the base 140 faces the bearing seat or seal, or as shown in FIG5, the drive disc 110 can be latchably connected to the handle 105 such that the edge 145 faces the bearing seat or seal. Instruction manual, pages 3 / 4, CN 121756289 A

[0026] The reversibility of the drive disc 110 improves the overall versatility of the tool 100 because it allows the drive disc 110 to be used in either a first or second position. In the first position, the base 140 faces outward, so the base 140 can be used to apply bearing races. In the second position, the edge 145 faces outward for applying seals. By removing the drive disc 100 by overcoming the holding force of the ball 135, rotating the drive disc 110 180 degrees to flip it over, and then reattaching the drive disc 100 to the handle 105, the user can easily flip the drive disc 100 between the configuration in which the drive disc 110 is most suitable for installing bearing races and the opposite configuration in which the drive disc 100 is suitable for installing seals.

[0027] Referring to FIG3, as described above, the drive disc 110 includes a base 140 and an edge 145. Figure 3 shows more clearly an embodiment of the groove 155, in which the ball 135 can engage with the groove 155 during the connection of the drive disc 110 and the handle 105.For example, by first inserting the actuator 130 into the opening 150, the ball 135 can be inserted into the recess 155. Before reaching the recess 155, the ball 135 will be pressed inward within the actuator 130, but when the actuator 130 is located within the opening 150, the ball 135 is axially biased outward. Once the actuator 130 has been pushed into the opening 150 a sufficient amount, the ball 135 will be biased outward and engage the recess 155 to lockably connect the handle 105 to the drive disc 110.

[0028] As shown, the recess 155 does not need to be a conventional recess and can be any type of recess capable of accommodating the ball 135 and connecting the handle 105 to the drive disc 110. For example, but not limited to, the recess 155 can be a hemispherical or other shaped recess, and the recess 155 does not need to extend circumferentially completely or even partially around the inner surface of the opening 150.

[0029] As used herein, the term "connection" and its functional equivalents are not necessarily limited to a direct mechanical connection of two or more components. Rather, the term "connection" and its functional equivalents are intended to represent any direct or indirect mechanical, electrical, or chemical connection between two or more objects, features, workpieces, and / or environmental elements. In some instances, "connection" is also intended to represent the integration of one object with another. Furthermore, the terms "lockable" and "releasable" are used interchangeably.

[0030] The matters set forth in the above description and drawings are for illustrative purposes only and not for limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications can be made without departing from the broader aspects of the inventors' contributions. The actual scope of protection sought, when viewed from a suitable perspective based on the prior art, is defined by the appended claims.Instruction Manual 4 / 4 Page 6 CN 121756289 A Figure 1 Figure 2 Instruction Manual Appendix 1 / 4 Page 7 CN 121756289 A Figure 3 Figure 4 Instruction Manual Appendix 2 / 4 Page 8 CN 121756289 A Figure 5 Figure 6 Instruction Manual Appendix 3 / 4 Page 9 CN 121756289 A Figure 7 Instruction Manual Appendix 4 / 4 Page 10 CN 121756289 A Abstract Disclosed is a bearing race and seal driving tool with a grip that is molded to receive a user's hand while having a cap that can be struck by a hammer during use.
