Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, specifically a walking gearbox that is easy to disassemble and maintain. Background Technology

[0002] The traveling gearbox is a crucial component in mechanical equipment used for transmitting power and changing motion. It is widely used in various traveling machinery, such as construction machinery and agricultural machinery. An existing patent, CN204271821U, describes a traveling gearbox for a small vehicle. It includes a gearbox mounted on the upper surface of a cast housing. The cast housing contains sequentially meshing gears. The axis of the input shaft is perpendicular to the axis of the hollow output shaft. A connecting flange is added at the connection point between the motor and the cast housing. A coupling connects the motor's input shaft to the input shaft of the cast housing. This invention adds a connecting flange at the connection point between the motor and the cast housing, avoiding the need for a custom motor, reducing product price, and lowering the risk of oil leakage due to poor sealing at the motor output shaft. The coupling is a flexible, perforated coupling, which has advantages such as compact structure, reliable operation, a wide torque transmission range, and overload protection. The input shaft of the cast housing is mounted on the second half of the coupling's bushing, shortening the axial dimension of the input shaft and making the gearbox structure more compact.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Existing walking gearboxes have the following problems: First, their housing structure is complex, and the connection between components is cumbersome, making the disassembly and assembly process very difficult and requiring a lot of time and manpower; Second, the internal component layout is unreasonable, and during maintenance, the space for inspection and replacement of some key components is limited, increasing the difficulty of maintenance. Therefore, we propose a walking gearbox that is easy to disassemble and maintain to solve the above-mentioned problems. Utility Model Content

The balance bracket 3 can be guided by the guide groove 1012 to provide a rotational support foundation for the planetary gears 3011 and ensure the stable operation of the planetary gears 3011.

[0027] See Figures 1-3 The outer side of the housing mechanism 1 is fixedly connected with an installation component 101. There are four installation components 101 in total, and the four installation components 101 are fixedly connected to the four sides of the outer side of the housing mechanism 1 respectively.

[0028] By fixing four mounting components 101 to the four sides of the outer side of the housing mechanism 1, the gearbox can be fixedly installed with external equipment through the mounting components 101, thereby improving the convenience of installation and structural stability.

[0030] The mounting slot 1011 is opened inside the mounting component 101, the bottom end of the housing mechanism 1 is embedded with the first bearing seat 1013, and the top end is equipped with the cover plate mechanism 2. The mounting slot 1011 can be used to assemble other components, the first bearing seat 1013 provides support for the output shaft 3013, and the cover plate mechanism 2 is used to cover the opening at the top of the housing.

[0031] See Figures 1-2 The cover plate mechanism 2 is used to cover the top opening of the box mechanism 1, and mounting holes 201 are provided at the four corners inside the cover plate mechanism 2 and at the four corners of the top surface of the box mechanism 1.

[0032] Mounting holes 201 are provided at the four corners of the top surface of the cover plate mechanism 2 and the box mechanism 1. The cover plate mechanism 2 and the box mechanism 1 can be connected by positioning bolts 2011 through the mounting holes 201 to achieve the fixed installation of the cover plate mechanism 2.

[0033] See Figures 3-5 The mounting hole 201 is a screw hole structure, and the cover plate mechanism 2 and the housing mechanism 1 are connected by a positioning bolt 2011. A through hole is opened at the center of the cover plate mechanism 2, and a second bearing seat 2012 is embedded in the through hole.

[0034] The cover plate mechanism 2 and the housing mechanism 1 are connected by a positioning bolt 2011 through the screw hole 201. The second bearing seat 2012 is embedded in the center of the cover plate mechanism 2. The positioning bolt 2011 enhances the structural stability. The second bearing seat 2012 provides support for the input shaft 3015.

[0035] See Figures 1-2 A positioning guide rod 2013 is fixedly connected to the bottom end face of the cover plate mechanism 2. The main body of the positioning guide rod 2013 is a cylindrical structure, and there are four positioning guide rods 2013. The four positioning guide rods 2013 are fixedly connected to the bottom end face of the cover plate mechanism 2 in a ring array, and the positioning guide rods 2013 are matched with the positioning holes 301.

[0036] Four positioning guide rods 2013 are fixed in a ring array at the bottom of the cover plate mechanism 2. The positioning guide rods 2013 match the positioning holes 301 on the balance bracket 3. The balance bracket 3 can be accurately positioned and limited by inserting the positioning guide rods 2013 into the positioning holes 301.

[0037] See Figures 4-6A pressure block assembly 2014 is fixedly connected to the outer circumferential surface of the four positioning guide rods 2013. The pressure block assembly 2014 is used to press and cover the limiting balance bracket 3. The outer side of the planetary gear 3011 is meshed with a gear disk assembly 3012. The bottom end of the gear disk assembly 3012 is fixedly connected to an output shaft 3013 installed in the first bearing seat 1013. The inner side of the planetary gear 3011 is meshed with a sun gear 3014. The top end of the sun gear 3014 is fixedly connected to an input shaft 3015 embedded in the second bearing seat 2012.

[0038] The pressure block assembly 2014 is fixed on the outer circumferential surface of the positioning guide rod 2013 to press and cover the limiting balance bracket 3. The outer side of the planetary gear 3011 meshes with the gear disk assembly 3012 and is installed on the first bearing seat 1013 through the output shaft 3013.

[0039] During operation, the input shaft 3015 is embedded in the second bearing seat 2012 of the cover plate mechanism 2. When power is input from the input shaft 3015, it drives the sun gear 3014 to rotate. The sun gear 3014 meshes with the four planetary gears 3011 on the inner side, causing the planetary gears 3011 to start rotating at the bottom of the balance bracket 3.

[0040] The balance bracket 3 is installed in the guide grooves 1012 on the four sides of the inner wall of the housing mechanism 1. Its cross-shaped structure ensures that the planetary gears 3011 are stably distributed in a ring array. When the planetary gears 3011 rotate, their outer sides mesh with the gear disk assembly 3012, thereby driving the gear disk assembly 3012 to rotate.

[0041] The output shaft 3013, which is fixedly connected to the bottom of the gear assembly 3012, is embedded in the first bearing seat 1013 at the bottom of the housing mechanism 1. The rotation of the gear assembly 3012 outputs power through the output shaft 3013, realizing the power transmission function of the gearbox. The four mounting components 101 on the outside of the housing mechanism 1 are fixedly connected to the external equipment through the mounting groove 1011. The cover plate mechanism 2 is fixed to the top of the housing mechanism 1 through the mounting holes 201 at the four corners and the positioning bolts 2011. The four positioning guide rods 2013 at the bottom of the cover plate mechanism 2 are inserted into the positioning holes 301 of the balance bracket 3 to achieve precise positioning of the balance bracket 3. The pressure block assembly 2014 on the outer periphery of the positioning guide rod 2013 presses and limits the balance bracket 3 to ensure that it remains stable during transmission.

[0042] In summary, this device can effectively limit the movement of the balance support 3 by utilizing the positioning guide rod 2013.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
