Abstract
The utility model belongs to a speed reducer, which in detail is a decelerating cylinder formed by a double-cycloid gear speed reducer installed on the inner wall of a cylinder. The decelerating cylinder is characterized in that the speed reducer installed in the cylinder is a double-cycloid speed reducer, the output end of the speed reducer is directly connected with the inner wall of the cylinder, and the inside of the cylinder is also provided with a non-return device.
Description
The utility model belongs to a kind of speed reduction gearing, specifically a kind of speed-reducing drums that constitutes in the cylindrical shell that the double cycloid gear reductor is installed in.
In existing speed-reducing drums, a kind of speed-reducing drums (seeing ZL90206675.7) that constitutes in the cylindrical shell that cycloidal planetary gear speed reducer is contained in is arranged, its constructional feature is that the mouth of reductor utilizes tens bolts to be connected with the end cap of cylinder, during action, eccentric bushing in the motor drives cycloidal planetary gear speed reducer rotates, and makes the Cycloidal Wheel swing, after the pin wheel housing deceleration transmission, drive end cap by bolt and rotate, thereby make cylinder make slow rotation.The shortcoming of this structure is, because the transmission of power is that therefore, the stressing conditions of cylindrical shell is relatively poor by the rotation of cylindrical shell end drive cylindrical shell, next, the pinwheel working accuracy of this structure is higher, the assembling difficulty, and the 3rd, when running into fault, can not check.
The purpose of this utility model is that a kind of transmission of power of design is more suitable, convenient processing and manufacture, the speed-reducing drums of check voluntarily.
Its main technical schemes is this speed-reducing drums, comprise speed reduction gearing, a cylindrical shell (30) and a left side thereof, right end cap (52), (31), the left bearing pin frame (9) of hollow is installed in a left side respectively with bolster (24), in right end cap (52) and (31), right bearing pin frame (44) is fastened on the other end of bolster (24), after input shaft (1) passes the hollow parts of left bearing pin frame (9), at the fastening eccentric bushing in its end (49), eccentric bushing connects cycloid external gear (46) outward, speed reduction gearing is the double cycloid gear reductor, cycloid inner gear (19) is fastened on the inwall of cylindrical shell (30), cycloid external gear (46) and cycloid inner gear (19) engagement utilize Xiao's axle (47) to connect left bearing pin frame (9) and right bearing pin frame (44) respectively in the both sides of cycloid external gear (46); Tighten the inner ring of gauge member holdback (26) at bolster (24), the outer ring of holdback is fastened on the inwall of cylindrical shell (30); Bolt (20) with articulation between cycloid inner gear (19) and the cylindrical shell (30) is connected, and bolt (20) is positioned on the face of joint of cycloid inner gear (19) and cylindrical shell (30).
The utility model has the advantages that during work, the stressing conditions of barrel is better because the mouth of speed reduction gearing is connected with the middle part of cylinder inboard wall; Secondly, speed reduction gearing is the double cycloid gear reductor, compares with cycloidal planetary gear speed reducer, and its processing request is lower, and is easy to process easy; 3rd, the gauge member holdback is housed in cylindrical shell, on the transport plane in case break down, will check, phenomenon can not appear reversing, relatively safety.
