Description

Technical Field

[0001] The utility model relates to the technical field of driving wheels, in particular to a reliable transmission driving wheel. Background Art

[0002] In today's rapidly developing society, excavators, as a multifunctional engineering machinery, play an irreplaceable role in road construction and other occasions. There are many different types of walking mechanisms for engineering machinery such as excavators, such as tires or tracks, among which there is a chassis of the excavator that is mainly composed of driving wheels, guide wheels, sprocket wheels, supporting wheels and tensioning and buffering devices combined with tracks. The driving wheel is one of the important parts on the excavator chassis, and together with the power source, it constitutes the power component of the excavator when it is moving.

[0003] When the excavator is working, the gear teeth of the driving wheel are inserted into the grooves of the track link of the crawler. The continuous rotation of the driving wheel drives the crawler to roll, thereby driving the excavator forward.

[0004] When it rains, the soil in the working environment of the excavator becomes wet. When the excavator moves forward, the wet soil easily enters the gap between the groove of the track segment and the meshing gap of the drive wheel teeth. The soil constantly enters the gap and is constantly squeezed, accumulated and hardened by the teeth. This may cause the excavator to bounce when driving over the raised ground during meshing, making it easier for the teeth to disengage from the groove of the track segment or directly prevent the teeth of the drive wheel from entering the groove of the track segment normally.

[0005] In view of the above problems, a driving wheel auxiliary component is proposed for cleaning mud from the driving wheel when the driving wheel is running. Utility Model Content

[0006] The utility model aims to solve the problems in the prior art and provides a reliable transmission driving wheel.

[0010] The utility model is further configured as follows: the bristles close to the center of the gear teeth are short bristles, and the length of the top end of the short bristles extending into the gear teeth is 0.2 times the tooth height of the gear teeth.

[0011] The utility model is further configured as follows: the bristles are long away from the center of the gear teeth, and the length of the top end of the long bristles extending into the gear teeth is 0.5 times the tooth height of the gear teeth.

[0012] The utility model is further configured as follows: a plurality of mounting holes are formed on the body shell, the mounting assembly is two bases of the same shape and symmetrically arranged, the two bases are formed with openings at positions corresponding to the mounting holes, the two bases are fixedly connected by a plurality of bolts respectively penetrating the openings and the mounting holes, and the two bases are fixedly connected to the adjusting component.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] Reliable transmission drive wheel, such as Figure 1 and Figure 2 As shown, it mainly includes a driving wheel body 1 with DH370 model parameters and twenty-one gear teeth 11, wherein the driving wheel body 1 is internally formed with an installation opening and twenty-eight threaded holes 12 distributed around the axis of the driving wheel body 1, a power source is arranged in the installation opening and is detachably connected to the driving wheel body 1 through a bolt 9 arranged in each threaded hole 12, the power source is arranged on the body shell of the engineering machinery, a mud cleaning component for removing mud on the gear teeth 11 is arranged at the top end, and an installation component for fixing the position of the mud cleaning component is arranged on the body shell, the driving wheel can be driven to rotate by the power source when the engineering machinery moves forward or backward, so that the mud in the gap between the two sides of the driving wheel and the chain track segment groove is removed from the driving wheel by the mud cleaning component, so as to effectively remove the mud that has been adhered to the gear teeth 11, and at the same time, it can also effectively reduce the probability of mud being brought into the position where the gear teeth 11 and the chain track segment groove are meshed.

[0023] like Figure 3 , Figure 4 as well as Figure 5As shown, the mud cleaning component includes a crank rod 2 arranged near the end face of the gear tooth 11 and an adjusting component for adjusting the position of the mud cleaning component arranged at one end of the crank. The crank sleeve is provided with a hair ring 3, and a plurality of rows of bristles 31 are arranged on the hair ring 3. The end of the crank rod 2 away from the mounting assembly is disassembled and connected to the limiting block 4. The adjusting assembly can reduce the distance from the axis of the crank rod 2 to the axis of the driving wheel body 1 as much as possible according to actual usage requirements. The bristles 31 arranged can more easily remove the mud on the gear tooth 11. At the same time, the hair ring 3 is arranged as a detachable component. By removing the limiting block 4, it can be easier to clean or replace the hair ring 3 when necessary, thereby effectively improving the overall service life of the mud cleaning component.

[0024] like Figure 3 , Figure 4 as well as Figure 5 As shown, the adjusting component includes a sleeve rod 5 and a spring 7 arranged in the sleeve rod 5. The outer end face of the sleeve rod 5 is fixedly connected to the installation component, and the inner side face of the sleeve rod 5 is slidably connected to the mud cleaning component. The two ends of the spring 7 are respectively in contact with the mud cleaning component and the sleeve rod 5. Due to the elastic force of the spring 7, the distance between the axis of the curved rod 2 and the driving wheel body 1 is slightly smaller than the outer diameter of the gear teeth 11. The gear teeth 11 are in contact with the curved rod 2, so that the curved rod 2 presses down the spring 7, thereby pushing the curved rod 2 in a direction outside the radius of the driving wheel. After that, the curved rod 2 will return to its position due to the action of the spring 7. While ensuring a better cleaning effect, the curved rod 2 will not be damaged by the gear teeth 11.

[0025] like Figure 3 , Figure 4 as well as Figure 5 As shown, the bristles 31 near the center of the gear tooth 11 are short bristles 311, and the top end of the short bristles 311 extends into the gear tooth 11 by a length that is 0.2 times the tooth height of the gear tooth 11. The short bristles 311 mainly clean the tooth surface near the center of the gear tooth 11. Since the mud is basically squeezed to the two sides of the gear tooth 11, and the mud accumulated in the center of the gear tooth 11 is pushed to the top, only shorter bristles 31 are needed to complete the cleaning of the gear tooth 11, and the bristles 31 away from the center of the gear tooth 11 are long bristles 312, and the top end of the long bristles 312 extends into the gear tooth 11 by a length that is 0.5 times the tooth height of the gear tooth 11. Since the mud is basically squeezed to the two sides of the gear tooth 11, the bristles 31 near the two sides of the gear tooth 11 need to be set longer to clean the two sides of the gear tooth 11.

[0026] like Figure 2As shown, a plurality of mounting holes are formed on the body shell, and the mounting components are two bases 6 of the same shape and symmetrically arranged. The two bases 6 are formed with openings at positions corresponding to the mounting holes. The two bases 6 are fixedly connected by a plurality of bolts 8 respectively inserted into the openings and the mounting holes. The two bases 6 are fixedly connected to the adjusting component, and the sleeve rod 5 is installed by combining the two bases 6 together, and only a plurality of bolts 8 are used to fix the bases 6, so that the entire mud cleaning component is very convenient when installing or disassembling.

[0027] In this specific embodiment, when the engineering machinery makes forward or backward movement, the gear teeth 11 on the driving wheel body will rotate continuously, pass through the bristles 31 of the bristle ring 3 of the mud cleaning mechanism for cleaning, and then enter into the groove of the chain track segment to engage with it. The long bristles 312 and the short bristles 311 can better fit the gear teeth 11 and clean the wet mud on the entire surface of the gear teeth 11.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
