Description

Technical Field

[0001] This invention relates to the field of bevel gears, specifically a stable bevel gear. Background Technology

[0002] In the field of mechanical transmission, bevel gears are a commonly used transmission component, widely applied in various mechanical equipment to achieve power transmission and motion conversion between different shafts. However, existing bevel gears have some problems that urgently need to be solved in practical use.

[0003] On the one hand, bevel gears generate a large amount of heat during high-speed operation due to gear meshing friction and other factors. If this heat cannot be dissipated effectively and in a timely manner, the temperature of the bevel gear body will rise sharply. Excessive temperature will not only accelerate the fatigue and wear of the gear material and reduce the service life of the gear, but may also cause thermal deformation of the gear, affecting the transmission accuracy and stability of the gear, and thus adversely affecting the normal operation of the entire mechanical system.

[0004] On the other hand, the stability of the connection between the bevel gear and the drive shaft is crucial. During the operation of mechanical equipment, the bevel gear will be subjected to significant torque and vibration impacts. If the connection between the bevel gear and the drive shaft is not secure enough, it is prone to loosening. Once the connection becomes loose, it will not only lead to a decrease in transmission efficiency, noise and vibration, but may also cause relative slippage between the bevel gear and the drive shaft, resulting in more serious mechanical failures, and even endangering the safe operation of the entire mechanical equipment.

[0005] Therefore, developing a bevel gear that has both good heat dissipation performance and can ensure a stable and reliable connection with the drive shaft is of great practical significance. Summary of the Invention

[0006] The purpose of this invention is to provide a stable bevel gear to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stable bevel gear, comprising a bevel gear body, a connecting handle inserted into one end of the bevel gear body, a drive shaft fixed to one end of the connecting handle, a plurality of side grooves formed on the surface of the connecting handle, a plurality of heat dissipation holes formed on the surface of the bevel gear body, heat inside the bevel gear body being dissipated through the heat dissipation holes and the side grooves, and an elastic metal limiting sleeve fixedly fitted on the shaft of the connecting handle, the elastic metal limiting sleeve being connected to one end of the bevel gear body.

[0008] Preferably, one end of the bevel gear body is provided with a connecting groove, the connecting groove is a square groove, the connecting handle is a square column structure, two through holes are provided inside the connecting groove, a screw is inserted into the through hole, one end of the screw is fixed to the surface of the connecting handle, and a nut is screwed onto the other end of the screw.

[0009] Preferably, there are four side grooves, which are respectively opened on the four annularly distributed side walls of the connecting handle. The length of the long side of the side groove is equal to the length of the long side of the connecting handle. A reinforcing block is inserted into one end of the side groove and fixed to the surface of the drive shaft.

[0010] Preferably, the heat dissipation hole 1 is provided in four groups, and the four groups of heat dissipation hole 1 correspond to four side grooves. After the connecting handle is inserted into the connecting groove, the side groove and the corresponding heat dissipation hole 1 are connected.

[0011] Preferably, the elastic metal limiting sleeve is an "I"-shaped circular plate, the inner ring opening of the elastic metal limiting sleeve is square, and four sets of heat dissipation holes are provided on the inner ring surface of the elastic metal limiting sleeve. One end of the heat dissipation hole connects to the outer ring groove of the elastic metal limiting sleeve, and the other end of the heat dissipation hole connects to the side groove.

[0012] Preferably, the two parallel side plates of the elastic metal limiting sleeve are provided with through holes II, and a screw II is inserted into each of the two sets of through holes II. A nut II is screwed onto one end of the screw II.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The stable bevel gear proposed in this invention features multiple side grooves on the surface of the connecting shank and multiple sets of heat dissipation holes on the surface of the bevel gear body. When the connecting shank is inserted into the connecting groove, the side grooves and the corresponding heat dissipation holes connect, forming a convection channel in the gap between the bevel gear body and the connecting shank. Heat generated inside the bevel gear body can be quickly dissipated through these convection channels, effectively improving the heat dissipation conditions of the bevel gear body, avoiding overheating caused by heat accumulation, thereby extending the service life of the bevel gear and improving its operational stability and reliability.

[0014] In addition, the four sets of heat dissipation holes on the inner ring surface of the elastic metal limiting sleeve are connected at one end to the outer ring groove of the elastic metal limiting sleeve and at the other end to the side groove, which further enhances the heat dissipation effect and forms a more complete heat dissipation system, ensuring that the bevel gear can maintain a good temperature state during long-term high-load operation.

[0015] The side groove not only participates in the heat dissipation process, but the reinforcing block inserted at one end also enhances the connection strength between the connecting handle and the drive shaft. The elastic metal limiting sleeve serves both to reinforce the connection and prevent loosening, and its second heat dissipation hole, together with the side groove and the first heat dissipation hole, forms a heat dissipation network. This integrated structural design significantly improves the heat dissipation and connection stability of the bevel gear. The various components cooperate and complement each other, fully demonstrating the scientific and advanced nature of the technical solution of this invention. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7 This invention provides a technical solution: a stable bevel gear, comprising a bevel gear body 1, with a connecting handle 2 inserted into one end of the bevel gear body 1, and a drive shaft 3 fixed to one end of the connecting handle 2. A connecting groove 101, which is square, is provided at one end of the bevel gear body 1. The connecting handle 2 has a square column structure. Two through holes 102 are formed inside the connecting groove 101, and a screw 201 is inserted into each through hole 102. One end of the screw 201 is fixed to the surface of the connecting handle 2, and a nut 202 is screwed onto the other end of the screw 201. Thus, the bevel gear body 1 is mounted on the front end of the connecting handle 2 through the cooperation of the screw 201 and the nut 202.

[0020] To dissipate heat from inside the bevel gear body 1, the following approach was proposed: The surface of the connecting handle 2 has multiple side grooves 203, and the surface of the bevel gear body 1 has multiple sets of heat dissipation holes 103. Heat inside the bevel gear body 1 is dissipated through the heat dissipation holes 103 and the side grooves 203. There are four side grooves 203, each located on one of the four annularly distributed sidewalls of the connecting handle 2. The length of the long side of each side groove 203 is equal to the length of the long side of the connecting handle 2. A reinforcing block 301 is inserted into one end of each side groove 203 and fixed to the surface of the drive shaft 3. There are four sets of heat dissipation holes 103, corresponding to the four side grooves 203. After the connecting handle 2 is inserted into the connecting groove 101, the side grooves 203 and the corresponding heat dissipation holes 103 communicate. The heat dissipation holes 103 and the side grooves 203 form a convection channel in the gap between the bevel gear body 1 and the connecting handle 2, thereby dissipating the heat accumulated inside the bevel gear body 1 and improving the heat dissipation conditions of the bevel gear body 1.

[0021] To strengthen the connection between the bevel gear body 1 and the connecting handle 2, the following was proposed: An elastic metal limiting sleeve 4 is fixedly fitted onto the shaft of the connecting handle 2, and the elastic metal limiting sleeve 4 is connected to one end of the bevel gear body 1. The elastic metal limiting sleeve 4 is an "I"-shaped annular plate, and the inner ring opening of the elastic metal limiting sleeve 4 is square. Four sets of heat dissipation holes 401 are opened on the inner ring surface of the elastic metal limiting sleeve 4. One end of the heat dissipation hole 401 is connected to the outer ring groove of the elastic metal limiting sleeve 4, and the other end of the heat dissipation hole 401 is connected to the side groove 203. Two parallel side plates of the elastic metal limiting sleeve 4 are each provided with a through hole 402. A screw 403 is inserted into each of the two sets of through holes 402, and a nut 404 is screwed onto one end of the screw 403.

[0022] When the connecting handle 2 is inserted into the connecting groove 101, the elastic metal limiting sleeve 4 abuts against one side of the bevel gear body 1. The screw 403 passes through the through hole 402. After the nut 404 is screwed onto the corresponding screw 403, it is locked. At this time, the two parallel side plates of the elastic metal limiting sleeve 4 are clamped between the nut 404 and the bevel gear body 1, which acts as an elastic washer. This achieves the anti-loosening function after the connecting handle 2 and the bevel gear body 1 are connected together, thus ensuring the working stability of the bevel gear body 1 when it is installed at the end of the drive shaft 3.

[0023] The usage method of this stable bevel gear is as follows: One end of the connecting handle 2 is fixed to the drive shaft 3 to ensure a stable connection. Four reinforcing blocks 301 are respectively inserted into one end of the side grooves 203 on the four annularly distributed side walls of the connecting handle 2, and the reinforcing blocks 301 are fixed to the surface of the drive shaft 3. The elastic metal limiting sleeve 4 is fitted onto the shaft of the connecting handle 2. At this time, the elastic metal limiting sleeve 4 is an "I"-shaped annular plate with a square inner opening, which is compatible with the square column structure of the connecting handle 2.

[0024] Insert the connecting handle 2 into the square connecting groove 101 at one end of the bevel gear body 1, ensuring a tight fit between the connecting handle 2 and the connecting groove 101. After the connecting handle 2 is inserted into the connecting groove 101, the through hole 102 inside the connecting groove 101 corresponds to the screw 201 on the surface of the connecting handle 2. Screw the nut 202 onto the other end of the screw 201, allowing the bevel gear body 1 to be initially installed at the front end of the connecting handle 2 through the engagement of the screw 201 and the nut 202. At this time, the side groove 203 on the connecting handle 2 connects with the corresponding heat dissipation holes 103 on the surface of the bevel gear body 1. The four sets of heat dissipation holes 103 correspond to the four side grooves 203, forming a convection channel in the gap between the bevel gear body 1 and the connecting handle 2 to dissipate heat from the inside of the bevel gear body 1.

[0025] When the connecting handle 2 is inserted into the connecting groove 101, the elastic metal limiting sleeve 4 abuts against one side of the bevel gear body 1. Two parallel side plates of the elastic metal limiting sleeve 4 each have a through hole 402. A screw 403 is passed through both through holes 402, and then a nut 404 is screwed onto the corresponding screw 403 and tightened. At this time, the two parallel side plates of the elastic metal limiting sleeve 4 are clamped between the nut 404 and the bevel gear body 1, acting as elastic washers to prevent loosening after the connecting handle 2 and the bevel gear body 1 are connected.

[0026] During the operation of the bevel gear, the heat generated inside the bevel gear body 1 is dissipated through the convection channel formed by the heat dissipation hole 103 and the side groove 203. Simultaneously, four sets of heat dissipation holes 401 on the inner annular surface of the elastic metal retaining sleeve 4, one end of which connects to the outer annular groove of the elastic metal retaining sleeve 4, and the other end connects to the side groove 203, further assisting in heat dissipation and improving the heat dissipation conditions of the bevel gear body 1. Through these steps, the installation of the stable bevel gear is completed, ensuring the working stability of the bevel gear body 1 when installed at the end of the drive shaft 3.

[0027] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
