Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figures 1 to 3, a kind of compact unidirectional torque overload protective device, the outer ring (3) including being equipped with special-shaped arc slot,
Described outer ring (3) the integral barrel shape, outer ring inner hole have been evenly arranged 6-12 special-shaped arc slot, the special-shaped arc of the outer ring (3)
Slot is connected by first straight line section (7), second straight line section (8) and arc section (9), is serrated, the first straight line section (7)
The gradient of side is big, and the gradient of second straight line section (8) side is small, is equipped with driving shaft (1) in the outer ring (3), the driving shaft (1)
6-12 blind hole of 1-5 row's even circumferential arrangement is uniformly arranged along the circumference in outer circle；It is equipped in the blind hole oppositely oriented
And concentric small pressure spring (B1) and big pressure spring (B2), the blind hole top are provided with sliding pin (4), sliding pin (4) end is located at
It in the special-shaped arc slot of outer ring (3) and contacts, on the right side of the outer ring (3) and terminal pad (5) pass through seam allowance positioning welding, the connection
The seam allowance of size identical as outer ring (3) bore circular arc is equipped on the left of disk (5), right side is equipped with seam allowance and spiral shell with user's gear matches
Line connecting hole, the sliding bearing (6) are mounted in the inner hole of terminal pad (5), pass through circlip on the outside of the driving shaft (1)
(C1) special-shaped retaining ring (2) are fixed with.
As shown in Figure 4, Figure 5, the sliding pin (4) top set there are two inclined-plane constitute step, the inclined-plane of step side
Identical as the gradient of outer ring (3) first straight line section (7) side, the inclined-plane of the step other side is than outer ring (3) second straight line section (8) side
Gradient it is 5~10 ° big.
On the axis of user, terminal pad right end outer circle can install the gear or chain of user for the utility model integral installation
Wheel, and compressed with screw from shaft end, external impetus drives inverse (suitable) hour hands of outer ring to rotate, the elastic potential energy stored by pressure spring,
It drives sliding pin that inverse (suitable) hour hands of driving shaft is driven to rotate, by the axis and key being mounted in driving shaft centre bore, outputs power
It is gone to subsequent transmission and executing agency, when driving shaft (backend load) becomes larger, sliding pin is oblique along straightway in special-shaped arc slot
Face sliding, pressure spring further compressed, and increases torque value, if load further increases, when being more than rated moment value, sliding pin will be by
It squeezes completely to the hole of driving shaft, unidirectional torque overload protective device, which skids, realizes safety protection function；Complete machine is hampered when walking
Power, terminal pad (front end) reduction of speed drive special-shaped arc slot outer ring is synchronous to slow down, and driving shaft continues under load inertia effect with original
Speed is simultaneously rotated with inverse (suitable) clockwise, and sliding pin is driven easily to slide simultaneously from the small gradient straightway and arc section of zigzag slot
Rotation, sliding bearing rotate on user's axis, have not only saved installation space, but also the steady reliably working of energy, have reduced transmission system
Impact.
