Description

Technical Field

[0001] This utility model relates to the field of worm gear technology, specifically a worm gear with a cooling channel. Background Technology

[0002] A worm gear is a component in mechanical transmission, which, when meshed with a worm, forms a worm gear drive. As the larger gear in an interlocking gear pair, when it meshes with the paired worm, this gear is called a worm gear. Worm gears are usually modified helical gears, and their pitch surface is often an annular surface, but it can also be a cylindrical surface or a plane.

[0003] Existing worm gear mechanisms are typically used to transmit motion and force between two intersecting shafts. When the worm gear and worm mesh, on the one hand, the force between the meshing gears is large, resulting in high friction loss; on the other hand, the relative sliding speed between the meshing gears is high, causing severe wear on the tooth surface and significant heat generation, which is difficult to dissipate, affecting the working performance of the worm gear. Therefore, we need to propose a worm gear with a cooling channel. Utility Model Content

[0004] The purpose of this invention is to provide a worm gear with cooling channels. By opening a direct inlet channel, a side inlet channel, a connecting channel, and a heat dissipation ring channel, and connecting them with the air inlet and side inlet, the airflow entering the worm gear body is increased. At the same time, the contact area between the incoming air and the worm gear body is increased. Furthermore, when using coolant for cooling, the coolant enters the worm gear body through the air inlet and side inlet, thereby further increasing the contact area between the coolant and the worm gear body, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a worm gear with a cooling channel, comprising a worm gear body, wherein a plurality of sets of worm gear teeth are fixedly arranged on the outer arc surface of the worm gear body;

[0006] Each set of worm gear teeth has a V-shaped groove on the side away from the worm gear body, and an auxiliary heat dissipation component is provided inside the V-shaped groove to improve the heat dissipation effect.

[0007] The worm gear body is equipped with a cooling component for accelerating the cooling process; the cooling component includes:

[0008] Two sets of heat dissipation annular channels are formed inside the worm gear body;

[0009] Several sets of direct-entry channels are opened inside the worm gear body and connected to the heat dissipation ring channel.

[0010] Preferably, the auxiliary heat dissipation component includes heat dissipation blades and rotating columns, and several sets of heat dissipation blades and rotating columns are provided. Several sets of rotating columns are rotatably disposed inside corresponding V-shaped grooves, and several sets of heat dissipation blades are fixedly disposed on the outer arc surface of corresponding rotating columns.

[0011] Preferably, the outer arc surface of the worm gear is provided with two sets of air inlets located between each pair of worm gear teeth, and several sets of air inlets are connected to the corresponding direct inlet channels.

[0012] Preferably, each set of worm gear teeth has two sets of side inlets on both sides, and each set of worm gear teeth has a side entry channel corresponding to the side inlets inside.

[0013] Preferably, each set of worm gear teeth has two sets of connecting channels inside, and several sets of side entry channels are connected to the corresponding straight entry channels through the connecting channels.

[0014] Preferably, the worm gear body has a plurality of side heat dissipation holes through the side, and the worm gear body has a connecting hole through the side, and the plurality of side heat dissipation holes are not connected to the connecting hole, the direct channel and the connecting channel.

[0015] Preferably, each set of heat dissipation blades does not contact the worm gear teeth, and the height of each set of heat dissipation blades does not exceed the outer end of the worm gear teeth.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention improves the airflow into the worm gear body by creating a direct inlet channel, a side inlet channel, a connecting channel, and a heat dissipation ring channel, all connected to the air inlet and side entrance. This increases the contact area between the incoming air and the worm gear body. When using coolant, the coolant enters the worm gear body through the air inlet and side entrance, further increasing the contact area between the coolant and the worm gear body. This enhances the cooling efficiency of the worm gear body, prevents the heat generated by friction during worm gear meshing and worm rotation from being difficult to dissipate, and thus improves the working performance of the worm gear and ensures its stability during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, a worm gear with a cooling channel includes a worm gear body 1, on which several sets of worm gear teeth 3 are fixedly arranged on the outer arc surface. Each set of worm gear teeth 3 has a V-shaped groove 5 on the side away from the worm gear body 1. An auxiliary heat dissipation component for improving heat dissipation is arranged inside the V-shaped groove 5. The auxiliary heat dissipation component includes heat dissipation blades 6 and rotating columns 9. Several sets of heat dissipation blades 6 and rotating columns 9 are arranged. Several sets of rotating columns 9 are rotatably arranged inside the corresponding V-shaped grooves 5, and several sets of heat dissipation blades 6 are fixedly arranged on the outer arc surface of the corresponding rotating columns 9. Limiting posts are provided at both ends of the rotating columns 9, and the rotating columns 9 pass through the limiting posts. The worm gear teeth 3 are connected to each set of rotating columns 9, ensuring that each set of rotating columns 9 can rotate within the corresponding V-groove 5. This allows the side inlet 8 to rotate under the influence of natural wind. The V-groove 5 increases the contact area between the worm gear teeth 3 and the outside air, allowing the outside air to naturally cool the worm gear teeth 3. When the worm gear body 1 rotates, the heat dissipation blades 6 inside each set of V-grooves 5 come into contact with the outside air, causing the heat dissipation blades 6 to rotate. The rotation of the heat dissipation blades 6 further removes the high temperature from the surface of each set of worm gear teeth 3, thereby further enhancing the overall cooling effect of the worm gear.

[0025] It is worth noting that each set of heat dissipation blades 6 does not contact the worm gear teeth 3, and the height of each set of heat dissipation blades 6 does not exceed the outer end of the worm gear teeth 3. The outer arc surface of each set of heat dissipation blades 6 is located inside the V-groove 5, thereby ensuring that each set of heat dissipation blades 6 is completely located inside the worm gear teeth 3, avoiding friction between the heat dissipation blades 6 and the worm when the worm gear meshes with the worm, and thus ensuring the stability of the worm gear during the rotation of the heat dissipation blades 6.

[0026] Furthermore, the worm gear body 1 is equipped with a cooling component to accelerate the cooling speed. The cooling component includes: two sets of heat dissipation ring channels 13 opened inside the worm gear body 1; and several sets of direct-entry channels 10 opened inside the worm gear body 1 and connected to the heat dissipation ring channels 13. With the center line of the worm gear body 1 as the midpoint, heat dissipation ring channels 13 and several sets of direct-entry channels 10 are opened on both sides of the center line. When the external natural wind enters the interior of the worm gear body 1 during rotation, it contacts the interior of the worm gear body 1 through the two sets of heat dissipation ring channels 13 and several sets of direct-entry channels 10, thereby quickly carrying away and cooling the high temperature inside the worm gear body 1, thereby improving the overall cooling effect of the worm gear body 1.

[0027] Furthermore, two sets of air inlets 7 are provided on the outer arc surface of the worm gear body 1 between each pair of worm gear teeth 3. Several sets of air inlets 7 are connected to the corresponding direct inlet channels 10. Two sets of air inlets 7 are provided between each pair of worm gear teeth 3, thereby increasing the intake of natural air. At the same time, it ensures that natural air can enter the heat dissipation ring channel 13 through the air inlets 7 and the direct inlet channels 10. The extruded air generated when the worm gear and worm are meshed can also enter the worm gear body 1 through the air inlets 7. At the same time, the coolant of the worm gear and worm can also enter the worm gear body 1 through the air inlets 7 to cool the inside of the worm gear body 1, thereby further improving the overall cooling effect of the worm gear body 1.

[0028] Furthermore, each set of worm gear teeth 3 has two sets of side inlets 8 on both sides, and each set of worm gear teeth 3 has a side entry channel 11 corresponding to the side inlet 8 inside. Each set of worm gear teeth 3 also has two sets of connecting channels 12 inside. Several sets of side entry channels 11 are connected to the corresponding direct entry channels 10 through the connecting channels 12. The side inlets 8 are opened on the side of each set of worm gear teeth 3, increasing the number of side inlets 8 and thus increasing the amount of natural air entering. The natural air entering through the side inlets 8 can cool the worm gear teeth 3 by passing through the side inlets 8. At the same time, some air enters the interior of the connecting channel 12 through the side inlets 8, and then enters the interior of the heat dissipation ring channel 13 through the connection with the direct entry channel 10, thereby cooling the interior of the worm gear body 1.

[0029] Furthermore, several sets of side heat dissipation holes 4 are provided through the side of the worm gear body 1, and a connecting hole 2 is provided through the side of the worm gear body 1. The connecting hole 2 is provided to facilitate connection with the output column, thereby achieving the effect of driving the worm gear body 1 to rotate. The several sets of side heat dissipation holes 4 are not connected to the connecting hole 2, the direct inlet channel 10 and the connecting channel 12. The several sets of side heat dissipation holes 4 are provided to cool the worm gear body 1 directly through natural wind. The side heat dissipation holes 4 do not contact the connecting hole 2, the direct inlet channel 10 and the connecting channel 12, thereby ensuring the overall quality of the worm gear body 1 and preventing the air entering the worm gear body 1 from being discharged through the side heat dissipation holes 4.

[0030] Working principle: The drive shaft is keyed to the worm gear body 1 through the connecting hole 2. The worm gear body 1 meshes with the worm through several sets of worm gear teeth 3. When the worm gear body 1 rotates as a whole, natural air enters the direct inlet channel 10, side inlet channel 11, connecting channel 12 and heat dissipation ring channel 13 through the air inlet 7 and side inlet 8, thereby increasing the contact area between natural air and the turbine as a whole, thus improving the overall cooling effect of the worm gear. When the worm gear body 1 rotates, the heat dissipation blades 6 inside each set of V-shaped grooves 5 come into contact with the outside air, thereby driving the heat dissipation blades 6 to rotate. The heat dissipation blades 6 further remove the high temperature on the surface of each set of worm gear teeth 3 through rotation, thereby further enhancing the overall cooling effect of the worm gear.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
