Description

Technical Field

[0001] The present application relates to the technical field of reduction gearbox assembly, and in particular to a reduction gearbox that is easy to disassemble. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.

[0003] The housing of the existing reducer is usually assembled by a large number of bolts or welding. When the housing of the reducer is disassembled, a matching wrench is required to disassemble it, and the thread is long, so disassembly is time-consuming and laborious, and it is impossible to disassemble quickly.

[0004] Therefore, it is necessary to provide a reduction gearbox that is easy to disassemble to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a reduction gearbox that is easy to disassemble, thereby solving the problem of inconvenient assembly and disassembly of the reduction gearbox.

[0007] The technical solution adopted by the present application to solve the technical problem is: a reduction box that is easy to disassemble, comprising two end shells, a connecting shell and a connecting assembly, wherein the connecting shell is located between the two end shells and is clamped with the end shells on the inner side; the connecting assembly passes through the end shells and is clamped with the connecting shell;

[0008] A plurality of right-angle rings are fixedly installed on the outer side of the end shell, and the plurality of right-angle rings are evenly arranged; a plurality of connecting seats are arranged on the outer side of the end shell, and the plurality of connecting seats are evenly arranged, and one connecting seat is spaced between two connecting seats;

[0009] The connecting assembly includes a built-in rod and a sliding seat; the end face of the sliding seat and the built-in rod are clearance-matched, and one end of the built-in rod passes through the sliding seat and is plugged into the connecting shell; the outer side of the sliding seat is connected to the inner wall of the connecting seat by a thread; thus, the right-angle ring facilitates the operator to control the end shell and reduces the workload of loading and unloading; the connecting shell cooperates with the end cover to install the gear set, and the connecting assembly replaces most of the threaded connections with a pin to strengthen the fixed connection between the end cover and the connecting shell, indirectly reducing the time of loading and unloading.

[0010] Furthermore, the outer side of the connection shell is evenly provided with connection parts, the connection parts are arranged circumferentially on the end surface of the connection shell, and the end of the connection part faces the adjacent end cover; the connection part is provided with a placement cavity and two limit cavities inside, the cavity bodies of the two limit cavities are connected with the placement cavity, and the end surfaces are perpendicularly staggered with the axial surface of the placement cavity, and the cavity bodies of the two limit cavities are located on the same straight line with the placement cavity;

[0011] A cap is provided at the placement cavity, and two limit plates are sleeved on the outer side of the cap, and the end faces of the two limit plates are parallel to each other and do not contact each other; the limit plates correspond to the limit cavities one by one, and the outer sides of the limit plates are slidably connected to the inner walls of the corresponding limit cavities; a spring is provided on one side of the limit plate, and one end of the spring away from the limit plate is fixedly connected to the end wall of the limit cavity; thereby, the spring keeps the limit plate in the middle section of the limit cavity and provides a driving force for the subsequent resetting of the cap.

[0012] Furthermore, the end surface of the connecting part is provided with two movable cavities, the placement cavity is located between the two movable cavities, and the cavity body and the movable cavity are connected; the built-in rod passes through one end of the connecting seat and extends into the placement cavity, and the end surface and the adjacent movable cavity are clearance-matched.

[0013] Furthermore, the built-in rod is provided with a plurality of arc-shaped plates at one end of the placement cavity, and the plurality of arc-shaped plates are circumferentially arranged in an umbrella shape, and the arc-shaped plates are made of metal leaf springs; the built-in rod is provided with a fixing ring on the outer side of the movable cavity, and the end face of the fixing ring is clearance-matched with the movable cavity; a second spring is fixedly installed on the side of the fixing ring away from the arc-shaped plate, and the end of the second spring away from the arc-shaped plate is fixedly connected to the sliding seat; thus, when the built-in rod with the arc-shaped plate passes through the connecting seat, it is squeezed and retracted to pass through the movable cavity and unfold at the placement cavity; then the thrust on the built-in rod is removed, and the second spring recovers from the stretched state, and pulls the built-in rod to move toward the sliding seat through the fixing ring, at which time the umbrella-shaped arc-shaped plate abuts against one end of the placement cavity, and cooperates with the sliding seat to fix the corresponding end shell with the connecting shell.

[0014] Furthermore, an annular groove is provided at one end of the sliding seat, a bearing member is installed at the annular groove, and one end of the bearing member is located outside the annular groove; the outer wall of the bearing member is fixedly connected to the large circular wall at the annular groove, and the inner wall of the bearing member located outside the annular groove is fixedly connected to the second spring; thus, when the sliding seat rotates at the connecting seat, it will not cause torsional fatigue to the second spring.

[0015] Furthermore, both ends of the cap member are provided with cap openings, and the inner wall of the cap openings is slidably connected to the outer side of the arc plate; therefore, when disassembly is required, the sliding seat is first rotated to loosen; the built-in rods corresponding to the two end covers are squeezed to make the corresponding umbrella-shaped arc plates gradually enter the cap openings and shrink, and then the two built-in rods are moved synchronously, and the cap member drives the limit plate to move in the limit groove to squeeze the spring one; after the arc plate facing the moving direction enters the active cavity, the corresponding built-in rod is taken out; the taken-out built-in rod is reversed, so that the straight rod (the end without the arc plate) extends into the vacant active cavity and abuts against the cap member, so that the built-in rod and the straight rod are kept relative to each other and move in another direction, and the corresponding retracted arc plate enters the adjacent active cavity, and then the built-in rod is taken out; thereby, the connecting shell and the end shell are no longer fixedly connected.

[0016] The beneficial effects of the present application are as follows: the present application provides a reducer that is easy to disassemble, which is convenient for operators to control the end shell by providing a right-angle ring, thereby reducing the workload of loading and unloading; it is also provided with a connecting assembly, which replaces most of the threaded connections with a latch to achieve a fixed connection between the end cover and the connecting shell, thereby indirectly reducing the time for loading and unloading, and does not require matching disassembly tools to work, thereby solving the problem of inconvenient loading and unloading of the reducer.

[0017] In addition to the above-described purposes, features and advantages, the present application also has other purposes, features and advantages. The present application will be further described in detail with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS
