Description
Technical Field
The utility model relates to a safety reducer, in particular to harmonic reduction gear with manual protection.
Background
At present, the harmonic gear reducer has the advantages of high precision, high bearing capacity and the like, so the harmonic gear reducer is widely used in the field of safety equipment, particularly valve switches of oil fields, deep wells, ships and the like.

The utility model provides a harmonic speed reducer ware with manual protection is in order to solve the unable normal use's of speed reducer ware under the outage condition the condition.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a harmonic speed reducer ware with manual protection solves the unable normal use's of reduction gear under the outage condition the condition.
The technical scheme is as follows: the harmonic reducer with manual protection of the utility model comprises a wave generator, a flexible bearing, a flexible wheel, a rigid wheel and a shell in sequence, wherein the rigid wheel is in threaded connection with the shell; the outer surface of the rigid wheel is connected with a rotating assembly in a meshing mode, the rotating assembly comprises a rotating gear meshed with the rigid wheel and an auxiliary shaft arranged concentrically with the rotating gear, and the auxiliary shaft can rotate relative to the shell.
By adopting the technical scheme, after power failure or other emergency occurs, the bolt between the shell and the rigid wheel is detached, then the auxiliary shaft is manually rotated, the auxiliary shaft drives the rotary gear to rotate, the rotary gear drives the rigid wheel to rotate, the rigid wheel drives the flexible wheel to rotate, the flexible wheel drives the main shaft to rotate, and the main shaft is used for outputting main power for opening or closing the door, so that the main shaft can be finally rotated to close the door in a manual mode.
Furthermore, a hand wheel is arranged on one transverse side of the auxiliary shaft and is positioned outside the shell.
Furthermore, the wave generator is embedded into the flexible wheel through the flexible bearing, the flexible wheel and the wave generator are arranged concentrically, and the axial depth of the flexible wheel is greater than that of the wave generator.
Furthermore, a boss is arranged at one end of the flexible wheel, which is far away from the wave generator.
Further, the edge of the wave generator is provided with a convex edge for limiting the axial movement of the flexible bearing.
Has the advantages that: compared with the prior art, the utility model: the door has two driving modes of manual driving and automatic driving, has better applicability, and can solve the problem of opening or closing the door under the condition of no electricity; the flexible wheel is lengthened to be stably fixed with the main shaft.
Drawings
FIG. 1 is a schematic diagram of a harmonic reducer with manual protection.
Detailed Description
As shown in fig. 1, a harmonic reducer with manual protection comprises a wave generator 1, a flexible bearing 2, a flexible wheel 3, a rigid wheel 4 and a shell (not shown in the figure) in sequence, wherein the rigid wheel 4 is in threaded connection with the shell; the outer surface of the rigid wheel 4 is connected with a rotating assembly 6 in a meshing manner, the rotating assembly 6 comprises a rotating gear 61 meshed with the rigid wheel 4 and an auxiliary shaft 62 arranged concentrically with the rotating gear 61, the auxiliary shaft 62 can rotate relative to the shell, and the hand wheel 7 is positioned outside the shell.
For better driving the auxiliary shaft 62, a hand wheel 7 is provided on one lateral side of the auxiliary shaft 62, and the hand wheel 7 is rotated to drive the auxiliary shaft 62 to rotate.
In order to maintain stable connection strength between the flexible wheel 3 and the main shaft, the wave generator 1 is embedded in the flexible wheel 3 through the flexible bearing 2, the flexible wheel 3 is arranged concentrically with the wave generator 1, and the axial depth of the flexible wheel 3 is greater than that of the wave generator 1.
In order to better match the flexible wheel 3 with the shell during assembly, one end of the flexible wheel 3, which is far away from the wave generator 1, is provided with a boss 8, and the boss 8 is embedded into an opening of the shell, so that the flexible wheel 3 is convenient to position.
During assembly, the flexible bearing 2 is firstly installed on the wave generator 1, and the wave generator 1, the flexible bearing 2 and the flexible wheel 3 are installed, so that the position of the flexible bearing 2 on the wave generator 1 can deviate, and therefore the edge of the wave generator 1 is provided with a convex edge 9 for limiting the axial movement of the flexible bearing 2.
The working process is as follows: after power failure or other emergency situations occur, the bolt between the shell and the rigid wheel 4 is detached, then the hand wheel 7 is manually rotated, the hand wheel 7 drives the auxiliary shaft 62 to rotate, the auxiliary shaft 62 drives the rotary gear 61 to rotate, the rotary gear 61 drives the rigid wheel 4 to rotate, the rigid wheel 4 drives the flexible wheel 3 to rotate, the flexible wheel 3 drives the main shaft to rotate, and the main shaft is used for outputting main power for opening or closing the door, so that the main shaft can be finally rotated in a manual mode to close the door.
