Abstract
The utility model relates to a mechanical stepless speed regulator whose gear is installed on a transmission shaft, and a plurality of moving tooth slices installed in a speed regulating disk are arranged below the transmission shaft whose shaft line and the shaft line of the tooth slice form 90 DEG to enable the gear is engaged and driven with the moving tooth slices; the stepless speed regulation is carried out through the gear sliding on the transmission shaft. The utility model has the advantages of dynamic speed regulation, reliable transmission and simple structure, having the wide application to the mechanical transmission systems of industries such as motor vehicles, machinery, mines, textiles, food products, etc.
Description
The utility model relates to a kind of mechanical stepless speed-regulating device, is used for the stepless speed regulation of various mechanical transmission.
At present, known mechanical stepless transmission has the engagement except that the toothed-chain type speed changer, and majority all is to utilize the frictional force of master driver and driven member contacting point to come transmitting movement, and realizes stepless change by the radius of clean-up that changes its contacting point.But the pretightening force that this mechanism needs is very big, in case load torque during greater than its output torque, generation is skidded, and the input power of prime mover can not be made full use of.Be difficult for skidding though gear chain type stepless variable speed unit has engagement, structure is complicated, and volume is big, and speed governing is slower.
The purpose of this utility model is that a kind of mechanical stepless arrangements for speed regulation will be provided, and has both adopted the tooth engagement to be difficult for skidding, and makes speed governing light again, and speed governing is fast.And simple in structure, volume is little.
The purpose of this utility model is achieved in that loads onto gear on transmission shaft, the speed disk that several motion gear pieces are housed is arranged on the below of transmission shaft, and the speed disk axis becomes 90 degree with drive shaft axis, and the motion gear piece surrounds 360 degree in speed disk.These motion gear pieces are supported by spring and contact with gear, and the between cog that embeds gear meshes, and when gear rotates, just drive speed disk and rotate.Gear is radially slided at transmission shaft upper edge speed disk, and the rotating speed of speed disk just changes continuously, reaches the purpose of stepless speed regulation.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is an embodiment's of the utility model a tectonic maps.
Among Fig. 1, gear (2) is contained on the transmission shaft (1), uses key connecting between gear (2) and transmission shaft (1), and gear (2) is rotated with transmission shaft (1) and slip thereon.Speed disk (3) is arranged on the below of transmission shaft (1), and its axis becomes 90 degree with the axis of transmission shaft (1), and motion gear piece (4) is contained in the speed disk (3), surrounds 360 degree.Be drilled with a hole in the bottom of motion gear piece (4), spring is loaded on that supporting movement gear piece (4) contacts with gear (2) in the hole, makes motion gear piece (4) embed the between cog engagement of gear (2).
Claims (2)
1, a kind of mechanical stepless arrangements for speed regulation, gear is loaded on the transmission shaft, several motion gear pieces are housed in the speed disk are arranged on the below of transmission shaft, the speed disk axis becomes 90 degree with drive shaft axis, it is characterized in that: the motion gear piece is supported by spring and contacts with gear, embed the between cog engagement of gear, gear radially slides at transmission shaft upper edge speed disk.
2, mechanical stepless arrangements for speed regulation according to claim 1 is characterized in that: several motion gear pieces surround 360 degree in speed disk.
