Technical Field

[0001] This utility model relates to a guide sleeve structure for machining planetary carrier bearing holes, belonging to the technical field of bearing guide sleeves. Background Technology

[0002] The planetary carrier is one of the main components of the planetary gear transmission device, and the planetary carrier bearing hole is a key component on the planetary carrier, used to install the planetary gear shaft or bearing. When the planetary gear is used as a basic component, it is the part that bears a large external torque in the mechanism. The guide sleeve is a precision part used in mechanical equipment to guide and support moving parts. Its core function is to ensure coaxiality and smooth movement.

[0003] Currently, in planetary gear transmission devices, a guide sleeve is installed on the axial side of the planetary carrier bearing. The guide sleeve is located axially between the bearing end cover and the bearing. The guide sleeve supports and guides the shaft in the planetary carrier bearing to prevent shaft deviation and ensure axial and radial stability. However, as a component of the equipment, the guide sleeve is frequently worn and replaced. However, the guide sleeve is relatively heavy and, due to its installation position, is often restricted and difficult to disassemble and assemble. Therefore, there is an urgent need for a guide sleeve structure for machining planetary carrier bearing holes to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a guide sleeve structure for machining planetary carrier bearing holes, so as to solve the problems mentioned in the background technology. The structure of this utility model is reasonable, which can not only prevent the guide shaft connected to the bearing from deviating and ensure axial and radial stability, but also optimize the disassembly and assembly of the guide sleeve and reduce the difficulty of replacement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide sleeve structure for machining planetary carrier bearing holes, comprising a guide sleeve body, a left half guide sleeve, a right half guide sleeve, a top port, a base, a disassembly / assembly assembly, an outer thread, an internal clamping groove, an inner ring of the guide sleeve, a fastening protrusion, and a sealing ring. The guide sleeve body can be divided into two parts: a left half guide sleeve and a right half guide sleeve. Disassembly / assembly assemblies are provided at the top and bottom of the left half guide sleeve and the right half guide sleeve. An outer thread is provided on the upper middle part of the outer surface of the guide sleeve body. A top port is provided at the top of the guide sleeve body, and a base is provided at the bottom of the guide sleeve body. The upper middle section of the inside of the guide sleeve body... A ring of internal clamping grooves is provided at the position, and sealing rings can be installed in the internal clamping grooves. Multiple fastening protrusions are provided on the middle part of the inside of the guide sleeve body, and the fastening protrusions are located above the inner ring of the guide sleeve body. The disassembly and assembly components include two parts: a top disassembly and assembly component and a bottom disassembly and assembly component. The top disassembly and assembly component includes a protruding plate and a through hole. The protruding plate is provided at the top of the left half guide sleeve and the right half guide sleeve, and each protruding plate also has two through holes in the middle. The bottom disassembly and assembly component includes an alignment block and a threaded hole. The alignment block is provided at the base position of the left half guide sleeve and the right half guide sleeve, and each alignment block has a threaded hole in the middle.

[0006] Furthermore, the protruding plates at the top of the left and right half guide sleeves and the alignment blocks on the chassis are symmetrically configured.

[0007] Furthermore, the connection and fixation of the left and right half guide sleeves in the bottom disassembly component requires the use of bolts that are compatible with the threaded holes to screw the alignment block.

[0008] Furthermore, the connection and fixation of the left and right half guide sleeves in the top-level disassembly component requires the use of matching pins passing through the through holes for fixation.

[0009] Furthermore, the width of multiple fastening protrusions inside the guide sleeve body is flush with the inner ring of the guide sleeve.

[0010] Furthermore, the inner diameter of the sealing ring filled in the built-in groove is perpendicular and flush with the bottom opening of the guide sleeve body.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a guide sleeve structure for machining planetary carrier bearing holes, including a guide sleeve body 1, a left half guide sleeve 11, a right half guide sleeve 12, a top port 2, a base 3, a disassembly and assembly assembly 4, an outer thread 5, an internal clamping groove 6, a guide sleeve inner ring 7, a fastening protrusion 8, and a sealing ring 9. The guide sleeve body 1 can be divided into two parts: the left half guide sleeve 11 and the right half guide sleeve 12. Disassembly and assembly assemblies 4 are provided at the top and bottom of the left half guide sleeve 11 and the right half guide sleeve 12. An outer thread 5 is provided in the upper middle part of the outer surface of the guide sleeve body 1. A top port 2 is provided at the top of the guide sleeve body 1, and a base 3 is provided at the bottom of the guide sleeve body 1. An internal clamping groove 6 is provided in the upper middle section of the interior of the guide sleeve body 1. The built-in groove 6 can be used to install the sealing ring 9. Multiple fastening protrusions 8 are provided on the middle part of the guide sleeve body 1, and the fastening protrusions 8 are located above the guide sleeve inner ring 7 of the guide sleeve body 1. The disassembly and assembly component 4 includes two parts: the top disassembly and assembly component 41 and the bottom disassembly and assembly component 42. The top disassembly and assembly component 41 includes a protruding plate 411 and a through hole 412. The protruding plate 411 is provided at the top of the left half guide sleeve 11 and the right half guide sleeve 12, and each protruding plate 411 also has two through holes 412 in the middle. The bottom disassembly and assembly component 42 includes an alignment block 421 and a threaded hole 422. The alignment block 421 is provided at the base 3 of the left half guide sleeve 11 and the right half guide sleeve 12, and each alignment block 421 has a threaded hole 422 in the middle.

[0020] As the first embodiment of this utility model: the inner diameter of the sealing ring 9 after filling the built-in groove 6 is perpendicular and flush with the bottom opening of the guide sleeve body 1, and the width of the multiple fastening protrusions 8 inside the guide sleeve body 1 is flush with the inner ring 7 of the guide sleeve. This design, by adding a sealing ring 9 with the same inner diameter as the bottom opening of the guide sleeve body 1 to the guide sleeve, helps to enhance the tightness of the connection between the guide sleeve and the output shaft on the bearing, and can prevent shaft offset during rotation to a certain extent. The setting of multiple fastening protrusions 8 can enhance the contact surface between the guide sleeve itself and the output shaft. The protrusions 4 at the top of the left half guide sleeve 11 and the right half guide sleeve 12 The alignment block 421 on chassis 3 and 11 are symmetrically configured. This design uses two sets of symmetrical disassembly and assembly methods at the top and bottom to disassemble and assemble the guide sleeve, which reduces the difficulty of replacing the guide sleeve at the planetary carrier bearing position. The connection and fixation of the left and right half guide sleeves in the top disassembly and assembly component 41 requires the use of matching pins to pass through the through hole 412 for fixation. The connection and fixation of the left and right half guide sleeves in the bottom disassembly and assembly component 42 requires the use of bolts that are compatible with the threaded hole 422 to screw the alignment block 421.

In addition, the bottom layer disassembly piece corresponding to the bottom of the left half guide sleeve 11 and the right half guide sleeve 12 is also fixedly connected. 42 also needs to be fixedly connected. The left half guide sleeve 11 and the right half guide sleeve 12 bottom alignment block 421 are screwed together with the threaded hole 422 by bolts that are compatible with the threaded hole 422. In this way, the left half guide sleeve 11 and the right half guide sleeve 12 can be combined to form a complete guide sleeve body 1. A sealing ring 9 can be arranged in the built-in groove 6 inside the guide sleeve body 1 to enhance the fit between the guide sleeve and the output shaft. Then, the guide sleeve body 1 is installed along the output shaft of the bearing to the axial side of the bearing hole position of the star carrier. The outer thread 5 on the outer surface of the guide sleeve body 1 allows the guide sleeve body 1 to be connected to the surrounding area, which further ensures the stability of the guide sleeve itself.
