Description
Technical field
The present invention relates to diesel engine speed regulator technical field, specifically a kind of diesel engine speed regulator Speed sensing device.
Background technique
At present, for ensureing the stable operation of diesel engine, the Injection Pump of diesel engine is all equipped with speed regulator, speed regulator is a kind of automatic control tegulatingdevice, can according to the change of diesel load, automatically increase or decrease the fuel delivery of Injection Pump, thus under realizing different load situation, the confession of oil mass plays and regulates, ensure that the stabilization of speed of motor changes in very little scope.Speed regulator divides by function two speed governor, all-speed regulator, constant speed governer and comprehensive speed regulator, divides have pneumatic governor, mechanical speed governor, hydraulic speed governor and the centrifugal and vacuum governor such as mechanical-pneumatic, mechanical-hydraulic by revolution speed sensing.
Mechanical speed governor is comparatively extensive with the application of mechanical centrifugal formula, its structure usually as shown in Figure 1, it comprises cam shaft for diesel engine 1, connecting body 2, push rod 3, centrifugally fly block 5, Returnning spring 7 and fuel-flow control lever 6, it balances each other according to spring force and centrifugal force and carries out speed governing, during work, cam shaft for diesel engine 1 drives the centrifugal block 4 that flies to rotate by connecting body 2, centrifugally fly block 5 because the work of centrifugal force rotates for axially outer in order to the centrifugal block pin 4 that flies, after rotating speed reaches certain speed, the centrifugal the other end flying block 5 is by push rod 3 jack-up, compression reseting spring 7, Returnning spring 7 drives fuel-flow control lever 6, Fuel Delivery for Diesel Engines is reduced, reduce rotating speed, otherwise, when diesel engine speed low to certain rotating speed time, centrifugal block 5 centrifugal force that flies diminishes, Returnning spring 7 resilience, drive fuel-flow control bar 6, increasing oil mass supplies, improve rotating speed, speed regulator is exactly automatically regulate according to speed conditions like this, diesel engine is made to be in one section of stable rotary regimes.In FIG, usually by connecting body 2, push rod 3, centrifugally flies block 5, and the mechanism assembly that Returnning spring 7 forms is referred to as Speed sensing device, and the Speed sensing device of this structure also also exists following defect:
1, work time, the centrifugal block 5 that flies rotates around the centrifugal block pin 4 that flies, and easily causes Speed sensing device vibrate, centrifugal fly block pin wearing and tearing aggravate, affect the speed regulator life-span;
2, the foreign matter such as grease, grinding enters and centrifugally flies block pin 4 and centrifugally fly near block 5, easily causes the centrifugal block 5 that flies can not normally opening and closing, or centrifugal to fly block 5 opening and closing inconsistent, causes speed governing ineffective, even loses efficacy.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of speed governing to be quick on the draw, vibration abrasion is little, the diesel engine speed regulator Speed sensing device of long service life.
The technical solution adopted in the present invention is: provide a kind of diesel engine speed regulator Speed sensing device, comprise camshaft and Returnning spring, described camshaft is socketed with the seal chamber of truncated cone shape, described seal chamber is built with flow equilibrium medium, connecting key is provided with between seal chamber and camshaft, seal chamber and connecting key are slidably connected, sidewall and its central axis of seal chamber acutangulate, described Returnning spring is socketed on camshaft, and one end of Returnning spring and the small end of seal chamber offset.
After adopting above structure, diesel engine speed regulator Speed sensing device of the present invention due at seal chamber built with flow equilibrium medium, seal chamber and connecting key are slidably connected, camshaft drives seal chamber to rotate by connecting key, the centrifugal action that flow equilibrium medium in seal chamber is subject to is on sidewall, because the sidewall of seal chamber and central axis acutangulate, centrifugal force resolves into component forward, when rotating speed reaches certain degree, this centrifugal component promotes seal chamber and moves forward, pressed home spring, oil mass is reduced by the adjustment of fuel-flow control bar, reach the object of reduction speed, otherwise, after speed declines, centrifugal component reduces to some extent, Returnning spring resets, oil mass is increased by the adjustment of fuel-flow control bar, reach the object gathered way, flow equilibrium media flow performance of the present invention is good, dynamic balancing is rapid, single unit system is quick on the draw, solve vibration large, the problem of serious wear, increase substantially working life.
As preferably, described flow equilibrium medium is water, mercury or sand, can effectively reduce costs.
As preferably, the acute angle that the sidewall of described seal chamber becomes with central axis is 35
0~ 65
0, be preferred embodiment.
As preferably, the sidewall of described seal chamber is provided with gusset, and described gusset extends to small end by the large end of seal chamber, and gusset can play the effect of flow-disturbing, accelerates the self balancing of flow equilibrium medium.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 3, diesel engine speed regulator Speed sensing device of the present invention, comprise camshaft 1 and Returnning spring 7, camshaft 1 is socketed with the seal chamber 9 of truncated cone shape, seal chamber 9 is built with flow equilibrium medium 11, connecting key 8 is provided with between seal chamber 9 and camshaft 1, seal chamber 9 and connecting key 8 are slidably connected, specifically camshaft 1 and seal chamber 9 are provided with keyway, connecting key 8 is located in the keyway of camshaft 1 and seal chamber 9, be located at connecting key 8 part in camshaft 1 keyway and its tight fit connection, be located at connecting key 8 part in seal chamber 9 keyway and its recessed bond ing, seal chamber 9 is kept to slide, sidewall and its central axis of seal chamber 9 acutangulate, Returnning spring 7 is socketed on camshaft 1, one end of Returnning spring 7 and the small end of seal chamber 9 offset.
The present invention in the specific implementation, camshaft 1 and seal chamber 9 can be set as a keyway, also can be set as multiple keyway, flow equilibrium medium 11 can adopt water, mercury or sand, and the acute angle that the sidewall of seal chamber 9 becomes with the central axis of seal chamber 9 is 35
0~ 65
0, the sidewall of seal chamber 9 is provided with gusset 10, and gusset 10 is held greatly by seal chamber 9 and extended to small end, and gusset 10 is set as multiple, is evenly distributed on the sidewall of seal chamber 9.
The present invention is when specific works, camshaft 1 drives seal chamber 9 to rotate by the connecting key 8 in keyway, in seal chamber 9, flow equilibrium medium 11 and then rotates, due to the effect of centrifugal force, flow equilibrium medium 11 acts on the sidewall of seal chamber 9, sidewall is skewed, therefore the component of centrifugal force drives seal chamber 9 to slide on camshaft 1, when speed acquires a certain degree, centrifugal component is greater than the elastic force of Returnning spring 7, Returnning spring 7 is driven to compress, Returnning spring 7 is connected with fuel-flow control bar 6, by fuel-flow control bar 6, adjusting oil mass, and then reach the object of governing speed, the present invention is quick on the draw, overcome vibration large, the shortcoming that life-span is short.
