Abstract
A novel disc type overrun clutch is composed of a driving disc, a steel ball, a steel ball bracket, a compression spring, an adjusting plug screw, an end cover, an end cover bolt and a driven shaft. A hole belt is arranged on the driving disc along the radial direction, the compression spring and the steel ball bracket are arranged in the hole belt, the steel ball is arranged on the steel ball bracket, the adjusting plug screw is arranged on a hole opening of the driving disc, the end cover is arranged on the outside of the driving disc, and the bolt is arranged on the end cover. A groove is distributed on the external diameter of the driven shaft along the radial direction. The novel disc type overrun clutch is characterized by being short in mounting distance and simple in structure, has various functions of a friction overrun clutch in adjusting transmission torsion, is particularly suitable to use under circumstances where mounting space is narrow and the length of a traditional overrun clutch can not meet requirements.
Description
Technical field
The utility model relates to a kind of novel disc type free wheel device, belongs to field of mechanical technique.
Background technique
Free wheel device in the market has various ways, the installing space broad though the general diameter of shaft type free wheel device is less.
The model utility content
The purpose of the utility model is in order to overcome deficiency of the prior art, thereby a kind of novel disc type free wheel device is provided.
Novel disc type free wheel device is made up of driving disc, steel ball, steel ball carriage, pressure spring, adjusting plug screw, end cap, bolts and driven shaft; Said driving disc prolongs and radially has hole system, is provided with pressure spring and steel ball carriage in the system of hole, and the steel ball carriage is provided with steel ball, and said driving disc aperture is provided with the adjusting plug screw, and said driving disc is provided with end cap outward, which is provided with screw; Prolong the axial distribution groove on the said driven shaft external diameter.
Said groove size is identical with steel ball size.
Adopt the beneficial effect of technique scheme to be:
1, the utlity model has mounting distance weak point, characteristic of simple structure, have each item function that friction overdrive clutch is regulated the driving torque size.
2, it is narrower that the utility model is particularly suitable for installing space, and use under the situation that traditional free wheel device length can't satisfy.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-driving disc, 2-steel ball, 3-steel ball carriage, 4-pressure spring, 5-regulate plug screw, 6-end cap, 7-screw, 8-driven shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain:
Novel disc type free wheel device forms 8 by driving disc 1, steel ball 2, steel ball carriage 3, pressure spring 4, adjusting plug screw 5, end cap 6, bolts 7 and driven shaft; Said driving disc 1 prolongs and radially has hole system, and the quantity of hole system is looked the load rating of driving torque and decide, and driving disc 1 hole system can arrange row, also can be according to the needs layout multiple row of driving torque; Be provided with pressure spring 4 and steel ball carriage 3 in the system of hole, steel ball carriage 3 is provided with steel ball 2, and the size of driving torque is regulated through the turnover of the adjusting plug screw 5 in driving disc 1 aperture, is provided with end cap 6 outside the said driving disc 1, which is provided with screw 7; Prolong the axial distribution groove on driven shaft 8 external diameters, groove is neglected steel ball 2 diameters greatly and is decided, and does not limit the concrete size of driven shaft.
The utility model is regulated the pressure of pressure spring 4 through regulating plug screw 5; This pressure is pressed in steel ball 2 in driven shaft 8 corresponding grooves through steel ball carriage 3, and when the moment of torsion of this free wheel device transmission surpassed setting value, pressure spring 4 pressure can not be resisted the reaction force of drawing back from steel ball 2; At this moment steel ball 2 moves to regulating plug screw 5 directions; Leave driven shaft 8 grooves, also just cut off the transmission of moment simultaneously, play overload protective function.
The utility model is mainly used in the proper functioning of mechanical transmission fields protection transmission part, prevents that the driving force overload from causing unforeseen security incident or equipment failure.
