Description

Technical Field

[0001] The utility model belongs to the technical field of reducers and relates to a reducer, in particular to a flange reducer. Background Art

[0002] A flange reducer is a transmission device enclosed in a rigid housing. Composed of several gears, shafts, bearings, and other components, it is used to vary the speed and torque between the input and output shafts. Therefore, it is widely used in mechanical transmissions. Flange reducers are particularly effective in applications requiring precise and repeatable positioning, such as industrial robots and automated equipment. They are also a crucial component in CNC machine tools, printing machinery, and packaging machinery.

[0003] A search revealed a flange-type planetary reducer disclosed in Chinese patent literature [Application Number: 202222582242.9; Publication Number: CN219221167U]. This type of output shaft can be connected to external equipment via a flange connection. This connection structure occupies little installation space and offers excellent load capacity, allowing the flange-type planetary reducer of this invention to drive external equipment more stably and powerfully.

[0004] Although the flange-type planetary reducer disclosed in this patent is convenient for driving external equipment, the existing flange reducer requires a lead screw to be connected to a string shaft in order to achieve the lifting and lowering of the equipment, resulting in the reduction performance being limited by a single reducer. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a flange reducer. The technical problem to be solved by this utility model is: how to achieve the deceleration of the equipment while leaving a connection end to further connect the reducer in series to optimize the speed control function.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A flange reducer comprises a housing, a second flange being fixed on the right side of the housing, a transmission shaft being fixed in the second flange, a worm being rotatably connected to the left end of the transmission shaft, a turbine being meshed with the outer surface of the worm, a fixing ring being embedded in the turbine, a bump being integrally formed in the turbine, a groove being formed on the outer wall of the fixing ring to match the bump, and a lead screw being vertically fixed to the inner wall of the fixing ring;

[0008] The worm rotates in the shell, and a string shaft is fixed on one end of the worm away from the transmission shaft.

[0009] The working principle of the present invention is as follows: a transmission shaft, a string shaft, a worm, a turbine, and a housing constitute a reducer. In this process, the first bearing, the second bearing, and the first flange all play a supporting role for the turbine to improve stability, and a lead screw is arranged therebetween. The external motor fixes the outer surface on the second flange, the output end of the motor is fixed to the transmission shaft, the input shaft of the motor drives the worm to rotate, and the worm drives the turbine engaged with it to rotate. The turbine drives the lead screw to rotate through the limitation between the protrusion and the groove. An external lifting device is installed on the lead screw below the housing and is installed through a nut. The lead screw rotates through the threaded transmission between the lead screw and the equipment installation position and the external limiting rod or track to achieve lifting and lowering. The string shaft can be connected in series with the reducer for speed regulation.

[0010] The turbine and the top end of the lead screw are both arranged in the shell, the left end of the second flange is fixedly connected to the right side of the shell outer wall, the left side of the shell is fixed with a flange, and the string shaft passes through the flange and extends to the left side of the shell.

[0011] With the above structure, the lead screw and the housing are connected through the second flange, and the housing is installed in a fixed position through the mounting hole thereon, thereby increasing support for the lead screw and making the rotation of the lead screw more stable.

[0012] A first bearing is fixed on the inner wall of the shell, a movable end of the first bearing is fixedly connected to the lead screw, and a top end of a fixing ring is fixedly connected to a bottom end of the movable end of the first bearing.

[0013] With the above structure, the lead screw drives the movable end of the first bearing to rotate, the fixed ring connected to the bottom of the movable end of the first bearing rotates synchronously with the turbine, and the fixed end of the first bearing contacts the housing, so that the housing supports the lead screw and the turbine, making the rotation more stable.

[0014] A first flange is fixed to the bottom of the shell, and the first flange is rotatably connected to the lead screw via a connecting bearing.

[0015] With the above structure, the movable end of the connecting bearing rotates with the lead screw, and the fixed end of the connecting bearing maintains a fixed connection with the housing through the first flange, which supports the bottom end of the turbine and makes the internal structure of the reducer more stable as a whole.

[0016] A connecting ring is fixed at the bottom of the inner wall of the first flange, a through hole for passing the lead screw is opened in the middle of the top of the connecting ring, and a connecting bearing is arranged above the connecting ring.

[0017] With the above structure, the lead screw does not contact the housing during rotation, thus avoiding wear caused by relative movement.

[0018] Compared with the existing technology, this flange reducer has the following advantages:

[0019] 1. By setting a lead screw in the turbine, the worm drives the turbine to rotate and the lead screw rotates at the same time, realizing the synchronous lifting and lowering of the equipment or platform by the thread transmission. By setting the lead screw in the center of the turbine, the original output shaft of the reducer is freed up and can be used to connect an external reducer in series, thereby enriching the deceleration performance.

[0020] 2. By setting bearings and connecting rings on the upper and lower parts of the turbine to connect the outer shell and the turbine worm, the support for the turbine worm and the lead screw is increased, making its rotation more stable. BRIEF DESCRIPTION OF THE DRAWINGS
