Description
Technical field
The utility model relates to retarder, but is specifically related to a kind of speed reducer of intermittently-driving.
Background technique
The characteristics of existing gear reduction unit are: its input shaft behind the power source (like motor, internal-combustion engine), through gearing down, makes output shaft turn round continuously with constant rotating speed in succession, gives work mechanism with transmission of power.As require speed reducer output shaft to make intermittent running, and two kinds of methods are arranged usually: the one, timing turning off one is connected power source, and the 2nd, between power source and speed reducer input shaft, add clutch.Its deficiency is that the former must frequently stop and starting power source, causes adverse effect to dynamic power machine; The latter has increased outside transmission link, makes whole system complicated.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, a kind of compact structure, reliable, beautiful shape is provided, can realizes the dynamic intermittent running speed reducer of control automatically.
For realizing above-mentioned purpose; But the technological scheme of the utility model is the speed reducer of a kind of intermittently-driving of design; Comprise speed reducer input gear shaft, one-level gearing down gearwheel and double reduction driving gearshaft; Said one-level gearing down gearwheel is meshed with the gear that speed reducer is imported on the gear shaft, and said gearwheel is enclosed within on the double reduction driving gearshaft through the rolling bearing sky; It is characterized in that between said one-level gearing down gearwheel and double reduction driving gearshaft, be provided with and can control combined clutch/break that both combine or separate its, said gear is helical gear or is spiral gear.
Wherein, it is affixed that the wheel acies of said combined clutch/break passes through attachment screw and locating stud and one-level gearing down gearwheel; Center hole on said combined clutch/break is connected with the double reduction driving gearshaft through flat key; Combined clutch/break is by hydraulic driving.
The peripheral member of said combined clutch/break comprises by welding cylinder body, oil sealing, pressing plate and bolt and constitutes a sealing isolation zone, is used for the gear oil entering combined clutch/break of lubricated reducer gear and bearing with prevention.
The advantage and the beneficial effect of the utility model are: but speed reducer that should intermittently-driving is compared with prior art, owing between inner one-level gearing down gearwheel of speed reducer and double reduction driving gearshaft, be provided with hydraulic driving, can control combined clutch/break that both combine or separate its.Its compact structure, reliable, beautiful shape, can realize the automatic control of intermittent running; Adopt hydraulic driving, stable working, do not have rigid impact.Overcome the frequent starting power source of existing technology or between power source and speed reducer input shaft, add outside transmission link and make the complicated defective of whole system.
Description of drawings
But Fig. 1 is the structural representation of the utility model intermittently-driving retarder.
Among the figure: 1, rolling bearing; 2, screw; 3, straight pin; 4, one-level gearing down gearwheel; 5, double reduction gearwheel; 6, output shaft; 7, welding cylinder body; 8; Oil sealing; 9; Pressing plate; 10, bolt; 11, flat key; 12, double reduction driving gearshaft; 13, combined clutch/break; 14, input gear shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
Embodiment 1:
As shown in Figure 1; But the utility model is a kind of speed reducer of intermittent running; Comprise speed reducer input gear shaft 14, one-level gearing down gearwheel 4 and double reduction driving gearshaft 12; One-level gearing down gearwheel 4 is meshed with the gear that speed reducer is imported on the gear shaft 14, and gearwheel 4 is enclosed within on the double reduction driving gearshaft 12 through rolling bearing 1 sky; Be provided with the combined clutch/break 13 that to control its both combinations or separate between the two at one-level gearing down gearwheel 4 and double reduction driving gearshaft 12.Wheel acies at combined clutch/break 13 is affixed with locating stud 3 and one-level gearing down gearwheel 4 through attachment screw 2; Center hole on combined clutch/break 13 is connected with double reduction driving gearshaft 12 through flat key 11, and double reduction transmission gearwheel 5 fixedly connects with the output shaft 6 of speed reducer; Combined clutch/break 13 can be avoided rigid impact by hydraulic driving.Constitute a sealing isolation zone for comprising outside combined clutch/break 13, be used for lubricating the gear oil entering combined clutch/break of reducer gear and bearing with prevention by welding cylinder body 7, oil sealing 8, pressing plate 9 and bolt 10.
Working principle: when system start-up; Input gear shaft 14 receives the driving entry into service of power source; Drive one-level gearing down gearwheel 4 and rotate, at this moment, because of clutch disk is in disengaged position under the spring force effect; Can not give second level under drive gear axle 12 with transmission of power, speed reducer output shaft 6 remains static.When control system is sent work order; Pressure oil gets into working oil chamber, promotes the clutch disk contact that piston makes combined clutch/break 13, and the brake friction dish is thrown off; One-level gearing down gearwheel 4 combines with double reduction driving gearshaft 12; Drive second level under drive gear axle 12 rotation together, pass motion to speed reducer output shaft 6 by the double reduction Transmitted chains again, work mechanism gets into working state.When control system is sent " stopping " instruction, the working oil chamber release, and it is communicated with fuel tank; Piston reversing motion under the spring force effect; Clutch disk disengages, and oppresses the contact of brake friction dish simultaneously, realizes braking; Make double reduction driving gearshaft 12 stall immediately, eliminate the kinematic error that inertia causes.One-level gearing down gearwheel 4 is in idling conditions again, and the double reduction Transmitted chains is cut off once more, and output shaft shuts down, and work mechanism ends work.
Embodiment 2:
The friction disk of the hydraulic driving combined clutch/break 13 in the utility model must be worked under " wet type " state of cooling; Work fluid is hydraulic oil: and the lubricant oil of gear and bearing is gear oil; For avoiding both to mix, the utility model is provided with the isolation zone in combined clutch/break 13 peripheries.
The advantage of the utility model: the one, compact structure, beautiful shape; The 2nd, input shaft will be in rotation status all the time; The 3rd, adopt hydraulically powered combined clutch/break, stable working, reliable does not have rigid impact; The 4th, can realize the automatic control of intermittent running easily; The 5th, applied widely, market prospects are wide.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
