Description
The utility model is a kind of mechanical reducer, relates to gear drive.
General gear reducer Heavy Weight volume is big, for example the manufacturing processing technic of gear box casing is more complicated for component.The retarder of planetary gear mechanism has the big advantage of the little speed ratio of volume in light weight, but the requirement on machining accuracy height." machine-building " magazine the 7th phase of nineteen eighty-three the 44th page of report U.S. Allan newton company invention a kind of " novel superelevation retarder " (selecting from Design News82 February 15, P.74～75).The simple structure major part of this retarder is external gear, ring gear, control panel.
The effect of " novel superelevation retarder " control panel is to make driving gear do translational motion around the axle center of retarder, can not rotation.X-axis direction on its plane has two bumps to be slidingly matched with the standing part of retarder, and the Y direction vertical with X-axis has two pins on two grooves and the driving gear to be slidingly matched on the plane.
The eccentric little axle of input shaft end cooperates with the center hole of driving gear, driving gear for example external gear since the restriction of control panel can only on orthogonal X-Y both direction, move, promptly with the axle center of retarder be the center of circle, with the side-play amount of eccentric shaft be the radius translation make circular movement.
Ring gear and external gear engagement, and can drive second level reducing gear by the eccentric shaft that is arranged on the side simultaneously, therefore this retarder can be connected into compound speed reducer.
The advantage of above-mentioned retarder is that the stressed of gear obtains an equitable breakdown, and the internal structure compactness can be connected into compound speed reducer.But it must have casing or the shell and the coupling of a retarder.
The primary purpose of the utility model is to provide a kind of retarder without casing; Next purpose of the utility model is to provide a kind of retarder that is directly installed on power such as motor or transmission device output shaft end, omits the coupling between retarder and the power input mechanism; It is to simplify the part of retarder that the utility model also has a purpose, utilizes the shell of power plant or end cap as the fixedly end cap of supporting retarder, directly exports language power by means of the outer ring of rotating.
Design proposal of the present utility model comprises the axis setting of the part of (1) retarder along input shaft; (2) by the direct outputting power of ring gear that rotates; (3) fixedly end cap is connected with power take-off; (4) adopt the gear with small teeth difference driving mechanism that comprises translational motion control panel device; (5) adopt machine oil or grease lubrication.
The utility model retarder is axial along power input shaft, is provided with fixedly end cap, control panel, external gear, ring gear and axle head end cap.The axis hole of external gear cooperates with the eccentric journal of power input shaft axle head inboard.The internal tooth of ring gear and the engagement of the external tooth of external gear, its outer rim both sides stretch out along the direction of central axis, and ring gear rotates outputting power.
One end of input shaft is equipped with fixedly end cap, and the other end is that axle head is equipped with the axle head end cap.The axis hole of axle head end cap is by the overhang bracket of input shaft.One end of ring gear is by fixedly end cap supporting, and the other end is connected with the axle head end cap.Control panel is fixedly between end cap and the external gear, it two pairs of orthogonal chutes of axis are radially arranged, a pair of chute cooperates with fixing pin and guide that fixed end covers, another cooperates with pin and guide on the external gear chute.Under the effect of fixing pin and control panel and input shaft eccentric journal, external gear can only prolong mutually perpendicular chute center line movement on the control panel, therefore external gear with the offset distance e of eccentric journal be the radius translation make circular movement, driven ring gear is outside outputting power.The velocity ratio of retarder equals the merchant of the ring gear number of teeth divided by the ring gear number of teeth and external gear number of teeth difference gained, and velocity ratio can reach 40:1～100:1.
Between input shaft and two the end cap axis holes, between eccentric journal and the external gear and fixedly between end cap and the ring gear bearing or bearing shell are being installed respectively.Retarder adopts machine oil or grease lubrication, fixedly between end cap and the ring gear, oil sealing is housed between oil cap and the axle head end cap.
When the utility model retarder is used for motor and other power or transmission device, the pto of motor can be used as input shaft of speed reducer, this moment, the fixedly end cap of retarder can be integrated with the end cap or the shell of power plant, retarder promptly is directly installed on the end of power plant, and the ring gear of rotation is by direct outputting power such as belt pulley, gear, sprocket wheel.
The structure of the utility model retarder is simple and direct, the output shaft of power plant and reducer input shaft become one, and retarder can omit bearing and the coupling that is connected with pto, and has dwindled the installing space that occupies.
The volume in light weight of the utility model retarder is little, only be equivalent to same reduction speed ratio worm speed reducer 1/10,1/5 of general gear reducer not only is applicable to general condition but also also can be suitable under the demanding specific condition of the little speed ratio of installing space.
The component of the utility model retarder are few, the part majority is common axle class, dish class shape, the manufacturing facility, do not need special machining accuracy, especially complicated casing casting and cutting have relatively been omitted with the conventional machinery speed reducer, save many machining periods and metallic material, reduced carrying or communications and transportation workload, work and economic benefit are improved.
In sum, the utility model retarder can be applied in many departments industry equipment, driving mechanism or detection, the testing apparatuss such as metallurgy, mine, building, chemical industry, weaving, light industry, electronics, in product specification, the aspect such as manufacture and install and use and obtain good benefit.
