Description

Technical Field

[0001] This utility model relates to the field of gear technology, and more specifically, to a detachable gear assembly. Background Technology

[0002] Cylindrical gears are an important type of gear in mechanical gears, and also the most common type of gear. Based on the direction of the teeth, cylindrical gears can be divided into spur gears, helical gears, and herringbone gears.

[0003] Most existing cylindrical gears are integral structures. If a part wears out during long-term use, the entire gear often needs to be scrapped and replaced. This not only wastes materials but also increases the cost of use and maintenance.

[0004] Therefore, a detachable gear assembly is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a detachable gear assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable gear assembly, including a long gear, a gear sleeve adapted to be fitted on the outside of the long gear, and a pressing block symmetrically slidingly arranged inside the long gear. Multiple plug-in components are supported between two pressing blocks, and each of the plug-in components passes through the long gear and is connected to the gear sleeve. Each of the pressing blocks is provided with a locking plug that is screwed onto the long gear on the outside.

[0007] Preferably, the long gear has multiple through-holes in a ring shape in the middle, and the corresponding gear sleeve has multiple slots on its inner wall.

[0008] Preferably, the inner wall of the gear sleeve is provided with multiple tooth grooves, and the tooth grooves mesh with the teeth of the long gear.

[0009] Preferably, one end of the extrusion block is provided with a conical extrusion section, and the conical extrusion sections of the two extrusion blocks cooperate to form an adjustable clamping groove with a V-shaped cross section.

[0010] Preferably, the plug-in assembly includes a plug plate, a stop block, and a sliding part. The stop block is welded to both sides of the bottom end of the plug plate, and two sliding parts are inclinedly arranged at the bottom of the plug plate.

[0011] Preferably, the two sliding parts form a V-shaped force-bearing structure, and the V-shaped force-bearing structure is disposed in a V-shaped adjustable clamping groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. When the long gear or gear sleeve is worn, only the worn part needs to be replaced, and the entire cylindrical gear assembly does not need to be scrapped;

[0014] 2. The gear sleeve can be fixed and disassembled by rotating the locking plug, which is convenient and saves time and labor costs;

[0015] 3. The combination of the plug-in assembly and the extrusion block forms a robust structure that ensures stability during transmission. Furthermore, the inner wall grooves of the gear sleeve mesh with the teeth of the long gear, ensuring synchronous rotation and improving transmission accuracy. Attached Figure Description

[0022] 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.

[0023] As attached Figure 1-5 The detachable gear assembly shown includes a long gear 1, with a gear sleeve 2 adapted to fit the outside of the long gear 1. A pressing block 4 is symmetrically slidably arranged inside the long gear 1. Multiple plug-in components 5 are supported between the two pressing blocks 4. Each of the plug-in components 5 passes through the long gear 1 and is connected to the gear sleeve 2. Each of the pressing blocks 4 is provided with a locking plug 3 that is screwed onto the long gear 1.

[0024] In practical implementation, by fitting the gear sleeve 2 onto the corresponding position of the long gear 1, and by rotating the locking plug 3, the locking plug 3 is pressed against the extrusion block 4, causing the extrusion block 4 to move closer to the middle of the long gear 1. This lifts up each insertion component 5, allowing each insertion component 5 to be ejected from the long gear 1 and embedded into the gear sleeve 2, thus fixing the gear sleeve 2. This allows the long gear 1 and gear sleeve 2 to form a robust structure, thus forming a combined cylindrical gear assembly. When the long gear 1 or gear sleeve 2 becomes worn, only the long gear 1 or gear sleeve 2 needs to be replaced, without causing the entire cylindrical gear to be scrapped. This reduces the use and maintenance costs of the cylindrical gear, and the whole assembly is easy to disassemble, simple to assemble, and has strong fixation.

[0025] The long gear 1 has multiple through-holes in a ring shape in the middle, and the corresponding gear sleeve 2 has multiple slots on its inner wall.

[0026] In practice, the gear sleeve 2 is fixed to the long gear 1 by the insertion component 5 being pushed out from the through-hole into the slot.

[0027] The inner wall of the gear sleeve 2 is provided with multiple tooth grooves, and the tooth grooves mesh with the teeth of the long gear 1.

[0028] In practice, by meshing the gear sleeve 2 onto the long gear 1, the long gear 1 and the gear sleeve 2 can rotate synchronously, thereby improving the transmission accuracy.

[0029] One end of the extrusion block 4 is provided with a conical extrusion section, and the conical extrusion sections of the two extrusion blocks 4 cooperate to form an adjustable clamping groove with a V-shaped cross section.

[0030] In practice, by moving the two pressing blocks 4 closer together or further apart, the included angle of the V-shaped adjustable clamping groove can be adjusted, thereby enabling the pressing adjustment of the plug-in assembly 5.

[0031] The plug-in assembly 5 includes a plug plate 501, a stop block 502 and a sliding part 503. The stop block 502 is welded to both sides of the bottom end of the plug plate 501, and two sliding parts 503 are inclinedly arranged at the bottom of the plug plate 501.

[0032] The two sliding parts 503 form a V-shaped force-bearing structure, and the V-shaped force-bearing structure is disposed in a V-shaped adjustable clamping groove.

[0033] In practice, by bringing the two conical extrusion parts closer together, the included angle of the V-shaped adjustable clamping groove becomes smaller. The conical extrusion parts extrude and press against the sliding part 503. The sliding part 503 is subjected to force and relative sliding occurs between it and the conical extrusion parts, causing the insert plate 501 to be pushed out from the through-hole and then inserted into the slot, thereby fixing the gear sleeve 2. After fixing the gear sleeve 2, the included angle of the V-shaped adjustable clamping groove is the same as the included angle of the V-shaped force-bearing structure, thereby improving the support connection surface of the sliding part 503, increasing the support strength, and further improving the firmness of fixing the gear sleeve 2.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
