Description

Technical Field

[0001] The invention belongs to the field of mechanical processing, and in particular relates to a spring weight balancing device for a helical angle rotary shaft of a gear grinding machine. Background Art

[0002] Due to work requirements, the worm gear assembly used for the helical angle of the gear grinder needs to be able to achieve a rotation of ±45° to process helical and spiral teeth. However, the worm gear assembly is equipped with components such as a grinding head, and the grinding head is often too heavy. When the worm gear assembly rotates, the overall center of gravity is not on the rotation axis of the worm gear assembly, so that when the worm gear assembly rotates, it will cause eccentricity, thereby generating a large torque, increasing the tooth surface pressure, and causing the motor load of the gear grinder to increase. It is necessary to design a structure to prevent the above hazards from occurring. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a spring weight balancing device for a helical angle rotary shaft of a gear grinding machine.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a spring weight balancing device for the helical angle rotating shaft of a gear grinding machine, comprising a worm wheel assembly, a worm, a gear grinding machine base, a spring seat group and a spring group, wherein the worm wheel assembly and the worm are arranged in the gear grinding machine, and the worm wheel assembly cooperates with the worm; the spring seat group comprises a spring seat I, a spring seat II, a spring seat III and a spring seat IV, wherein the spring seat I and the spring seat III are arranged on the vertical plane of the worm wheel assembly and are located above the horizontal rotating shaft of the worm wheel assembly, wherein the spring seat I and the spring seat III are symmetrical on both sides of the vertical rotating shaft of the worm wheel assembly, wherein the spring seat II and the spring seat IV are arranged on the vertical surface of the gear grinding machine base and are opposite to each other. Located on both sides of the vertical rotating shaft of the worm gear assembly, the spring seat II is located vertically below the spring seat I, and the spring seat IV is located vertically below the spring seat III; the spring group includes spring I, spring II, spring III and spring IV, and hooks are provided at both ends of the spring I, spring II, spring III and spring IV, the hook at the upper end of the spring I is fixed on the spring seat I, the hook at the lower end is connected to the hook at the upper end of the spring II, the hook at the lower end of the spring II is fixed to the spring seat II, the hook at the upper end of the spring III is fixed to the spring seat III, the hook at the lower end is connected to the hook at the upper end of the spring IV, and the hook at the lower end of the spring IV is fixed to the spring seat IV.

[0005] Preferably, the spring seat I, spring seat II, spring seat III and spring seat IV are installed on the same vertical plane.

[0006] Preferably, the springs I, II, III and IV have the same performance.

[0007] Beneficial effects: Compared with the prior art, the present invention has the following advantages: The present invention is mainly applied to the helical angle components of the grinding wheel gear grinder. By adding a spring counterweight structure to the rotating shaft of the worm wheel assembly used for the helical angle of the gear grinder, the torque caused by the eccentricity during the rotation of the grinding head can be effectively reduced, and the load of the rotating shaft motor can be greatly reduced.

[0010] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0011] like Figure 1 As shown, a spring weight balancing device for a helical angle rotary shaft of a gear grinding machine comprises a worm wheel assembly 3, a worm 5, a gear grinding machine base 11, a spring seat group and a spring group. The worm wheel assembly 3 and the worm 5 are arranged in the gear grinding machine, and the worm wheel assembly 3 and the worm 5 cooperate with each other; the spring seat group comprises a spring seat Ⅰ1, a spring seat Ⅱ6, a spring seat Ⅲ7 and a spring seat Ⅳ10, and the spring seat Ⅰ1, the spring seat Ⅱ6, the spring seat Ⅲ7 and the spring seat Ⅳ10 are installed on the same vertical plane, the spring seat Ⅰ1 and the spring seat Ⅲ7 are arranged on the vertical plane of the worm wheel assembly 3 and are located above the horizontal rotary shaft of the worm wheel assembly 3, the spring seat Ⅰ1 and the spring seat Ⅲ7 are symmetrical on both sides of the vertical rotary shaft of the worm wheel assembly 3, and the spring seat Ⅱ6 and the spring seat Ⅳ10 are arranged on the gear grinding machine base 1 1 and symmetrically on both sides of the vertical rotating shaft of the worm gear assembly 3, the spring seat II6 is located vertically below the spring seat I1, and the spring seat IV10 is located vertically below the spring seat III7; the spring group includes spring I2, spring II4, spring III8 and spring IV9, both ends of the spring I2, spring II4, spring III8 and spring IV9 are provided with hooks and have the same performance, the hook at the upper end of the spring I2 is fixed on the spring seat I1, the hook at the lower end is connected to the hook at the upper end of the spring II4, the hook at the lower end of the spring II4 is fixed on the spring seat II6, the hook at the upper end of the spring III8 is fixed on the spring seat III7, the hook at the lower end is connected to the hook at the upper end of the spring IV9, and the hook at the lower end of the spring IV9 is fixed on the spring seat IV10.

[0012] In the device, the helical angle spring I2 and spring II4, spring III8 and spring IV9 are hooked together, which can avoid the bending of the spring during the force compression process. The worm 5 cooperates with the worm gear assembly 3 to transmit the power of the motor to the worm gear assembly through the worm, thereby realizing the rotation of the helical angle component.

[0013] like Figure 1 As shown, at this time, the worm wheel assembly of the helical angle component is in the 0° state. When the helix angle rotates clockwise, due to the eccentricity of the helix angle load, torque will be generated, resulting in an increase in the contact pressure between the worm wheel assembly 3 and the worm 5. At this time, spring III8 and spring IV9 are in a relaxed state, while spring I2 and spring II4 are in a tensioned state, generating an opposite torque, which can effectively reduce the impact of the eccentric load; conversely, when the helix angle rotates counterclockwise, spring I2 and spring II4 are in a relaxed state, while spring III8 and spring IV9 are in a tensioned state.

[0014] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
