Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates to a kind of shaft coupling, specifically a kind of rolling
Bead safety coupling.
Background technology
Shaft coupling is connection parts the most frequently used in the transmission of axle system, couples two axles in different institutions
(driving shaft and driven shaft), is allowed to jointly rotate, and is used for transmitting torque.Under normal circumstances, shaft coupling
With connected compcnent synchronous revolving and not disengaging, do not change the size of torque.But, set at wind-power electricity generation
In Bei, shaft coupling, in addition to the requirement in terms of driving torque to be met, rotating speed, also wants emphasis to consider connection
The security of axial organ and insulating properties, have the shaft coupling of security and insulating properties, structure the most on the market concurrently
The most complicated and expensive, so needing a kind of simple in construction of design, having security and absolutely concurrently
The safety coupling of edge, this case thus produces.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, has the rolling of security and insulating properties concurrently
Bead safety coupling.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of ball-type safety coupling, inserts from two ends respectively including axle sleeve, driving shaft and driven shaft
In axle sleeve, between described driven shaft and the inner surface of axle sleeve, it is connected transmission, described master by spline
It is provided with insulation sleeve between moving axis and axle sleeve, between described insulation sleeve inner surface and driving shaft, passes through spline
Connect transmission；
Described insulation sleeve outer surface is evenly distributed with eight hemispherical projections, described axle sleeve inner surface
Correspondence position is evenly distributed with four circular holes, is provided with spring, described spring one end in described circular hole
Connecting the inwall of circular hole, the other end connects ball, and it is any that described ball falls into insulation sleeve outer surface
Between two hemispherical projections.
Further, end cap seal is passed through at described axle sleeve two ends, has through hole in the middle part of the end cap at two ends.
Further, it is provided with insulating trip between described driving shaft and driven shaft end.
Further, described insulation sleeve uses the high-strength insulating material such as nylon to make.
The beneficial effects of the utility model: the utility model is by arranging absolutely between driving shaft and axle sleeve
Spline is all used to connect transmission, absolutely between edge set, driving shaft and insulation sleeve and driven shaft and axle sleeve
Edge set outer surface arranges hemispherical projections, has circular hole at axle sleeve correspondence position, arranges bullet in circular hole
Spring connects steel ball, by the hemispherical projections on steel ball safety clutch insulation sleeve, it is achieved safe transmission,
When torque is excessive, skidding, make transmission interrupt between axle sleeve and insulation sleeve, big torque is released,
Thus protect the strength member on driven shaft to be unlikely to damage；Meanwhile, between driving shaft and driven shaft
Insulating trip, driving shaft and shaft room are set and are also provided with insulation sleeve, make shaft coupling have security and insulation concurrently
Property, and simple in construction, production cost are low.
Accompanying drawing explanation
With specific embodiment, the utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the utility model front section view.
Fig. 2 is the utility model side sectional view.
Detailed description of the invention
As shown in Figure 1-2, the utility model provides a kind of ball-type safety coupling, including axle sleeve
1, axle sleeve 1 two ends are sealed by end cap 2, reduce external environment to the pollution within shaft coupling.Two ends
End cap 2 in the middle part of have a through hole, driving shaft 3 and driven shaft 4 enter in axle sleeve 1 through through hole, main
Being provided with insulating trip 5 between moving axis 3 and driven shaft 4 end, insulating trip 5 is for cutting off connecing between two axles
Touch, reach the purpose of insulation.
Be connected transmission by spline between driven shaft 4 and the inner surface of axle sleeve 1, be positioned at driving shaft 3 with
Being provided with insulation sleeve 6 between axle sleeve 1, insulation sleeve 6 uses the high-strength insulating material such as nylon to make, absolutely
Edge overlaps and is connected transmission by spline between 6 inner surfaces with driving shaft 3, and insulation sleeve 6 outer surface uniformly divides
It is furnished with eight hemispherical projections 7, is positioned at axle sleeve 1 inner surface correspondence position and is evenly distributed with four circular holes 8,
Being provided with spring 9 in circular hole 8, spring 9 one end connects the inwall of circular hole 8, and the other end connects ball
10, time at spring 9 with nature, ball 10 stretches out circular hole 8, falls into insulation sleeve 6 outer surface
Between any two hemispherical projections 7.
Utility model works principle: when driving shaft 3 drives insulation sleeve 6 to rotate, on insulation sleeve 6
Hemispherical projections 7 extrude ball 10, ball 10 tangentially provides circumference turning moment, drives axle sleeve 1
Rotating, and then drive driven shaft 4 to rotate, ball 10 radial component is by the thrust-balancing of spring 9；When
When the torque of driving shaft 3 transmission is excessive, ball 10 radial component is more than the pressure of spring 9, then ball
10 are moved radially outwards, when the torque of driving shaft 3 transmission big the most to a certain extent time, ball 10 quilt
In press-in circular hole 8 so that skid between insulation sleeve 6 and axle sleeve 1, now, the torque of driving shaft 3
Can not be delivered to driven shaft 4 up, big torque is released, thus protects the part on driven shaft 4
Being unlikely to damage, when load recovers normal, ball 10 is released circular hole 8 by spring 9, again can be again
Transmission torque.
The utility model by arrange between driving shaft and axle sleeve insulation sleeve, driving shaft and insulation sleeve with
And between driven shaft and axle sleeve, all use spline to connect transmission, hemispherical is set at insulation sleeve outer surface convex
Rise, have circular hole at axle sleeve correspondence position, spring is set in circular hole and connects steel ball, pacified by steel ball
Hemispherical projections on full clutch insulation sleeve, it is achieved safe transmission, when torque is excessive, axle sleeve is with exhausted
Skid between edge set, make transmission stage casing, big torque be released, thus protect on driven shaft important
Part is unlikely to damage；Meanwhile, insulating trip, driving shaft and axle are set between driving shaft and driven shaft
Inner room is also provided with insulation sleeve, makes shaft coupling have security and insulating properties, and simple in construction, production concurrently
Low cost.
Above content is only to the utility model structure example and explanation, and this technology affiliated is led
Described specific embodiment is made various amendment or supplements or use similar by the technical staff in territory
Mode substitute, without departing from the structure of utility model or surmount defined in the claims
Scope, all should belong to protection domain of the present utility model.
