Abstract

The present invention relates to a balancer for piston machine, such as cross head diesel motor. The equaliser uses at least two weights which are lain side by side at the motor's base housing via parallel shafts (5,6). They are driven by a gear (7,8) from the crankshaft, counterrotating at twice its speed. The weights' turning circles intersect in side by side lying planes along the engine's longitudinal axis. So that it is compact and light in weight by arranging the device in the longitudinal direction of an engine.

Description

Inertial force balancing device
The present invention relates to the Equilibrator of a kind of large-scale motor such as cross-head diesel motor second level inertial force, have two counterweights, this counterweight is installed on the motor base side by side by parallel axes, and is driven with double revolution subtend by a bent axle speed changer by actuation gear respectively.
The cross-head diesel motor that has this kind pattern device disclosed in DE-PS 27 57 332.Each counterweight herein is contained between the supporting of two bearings, and this bearing is bearing on the gear shaft of expansion bearing and has special wheel hub.Whole width between this approximately fan-shaped counterweight is supported through bearing.Minimum separable between the counterweight is to determine like this, and promptly they must not pass through the other side in the running mutually with touching, and, by between the cycle circle of retouching out from axle outer surface farthest certain intervals being arranged also.Since the desired balancing mass of internal combustion (IC) Engine Design, the counterweight that this structure must be bigger, thus vertically require sizable space at motor.
The object of the invention is, designs a kind ofly vertically to require the smaller device in space at motor.
By being installed in the motor parallel longitudinal plane with the crossing form of its cycle circle, counterweight realizes in this class device by this purpose of the present invention.
Take this structural type, under the certain situation of given actuation gear spacing and second level trimming moment, counterweight quality and particularly thickness can reduce, because the change of quality can be the mean radius that changes Mass Calculation very simply and relied on, and when the desired centrifugal force of calculated mass balance will with this radius square.Use this invention, because the quality of counterweight thereby reducing of its thickness make counterweight vertically also reduce in shared space at machine.
According to a kind of advantageous embodiments, each counterweight comprises two partial equilibrium counterweights that are installed in the actuation gear both sides of respectively attaching troops to a unit.This makes structure very simple and compact.Advantageously the partial equilibrium counterweight does not require special wheel hub herein, because actuation gear can be played a supporting role.
Actuation gear preferably is installed between two bearings that are fixed on the motor base.This measure makes structure save the space, has avoided using the actuation gear of expansion bearing simultaneously, and this helps improving the rigidity that can reach.
Other favourable measures are provided by following illustrating by diagram.
Following being illustrated as:
The front view of Fig. 1 device provided by the present invention, it is based on a vertical cross-section of admitting in the large cross-head diesel motor between two support walls that the invention provides device
Fig. 2 the invention provides the horizontal section of device.
At this large-sized diesel motor that starts described pattern, can be the wheel boat motor, its basic structure and working principle are well known.Whole whole motor base by 1 representative has and stands on the underframe that comprises bent axle and perpendicular to the support wall 2 of the motor longitudinal axis.The Equilibrator of second level inertial force has been installed in zone between a support wall 2 that forms the support wall 2 of a motor end face and be adjacent.Thereby this device comprises and is fixed in the bearing 3,4 that is fixed on the so-called support wall 2 on the motor base 1, is parallel to motor axle 5,6 longitudinally in order to support two, and actuation gear 7,8 has been installed respectively on the axle.
Actuation gear 7,8 constitute the part of speed changer, this speed changer also has a gear 9 that is contained on the bent axle in addition, a gear 10 that is contained on the camshaft, a Tension gear 12 (spannzahnrad) that is bearing on the rocking arm 11, and one and two actuation gears 7,8, the chain 13 that gear 9,10 and balance gear 12 are meshed.Here two actuation gears 7,8 have at interval each other, do not intermesh.Chain 13 here is multistage chain.Has corresponding a plurality of parallel teeth schedule with the coefficient gear 7 to 10 and 12 of chain.The diameter of actuation gear 7,8 is half of gear 9, thereby with double revolution rotation.Also can replace described chain drive with gear-shift transmission, its form is that gear 7 to 10 and 12 interconnects by gear.
Be balance second level moment, as shown in Figure 2, connect the partial equilibrium counterweight 18,19 of two same types by bolt 16,17 flanges in actuation gear 7 outsides.Two counterweights 14,15 are fixed on the actuation gear 8 by bolt 20,21 in the same way.For this reason, partial equilibrium counterweight 14,15,18,19 has flange, and the bolt 16,17,20,21 on each counterweight screws in the flange.Pei Dui partial equilibrium counterweight 14,15 or 18,19 respectively constitutes total calculated equilibrium counterweight each other. Partial equilibrium counterweight 14,15,18,19 is installed in the adjacent plane, and like this, they can surpass half of distance between axle 5,6 axis with the cycle shown in dot and dash line circle 22,23 radiuses in Fig. 1, thereby can intersect, as clearly shown in Figure 1.
Partial equilibrium counterweight 14,15 should be installed on the actuation gear 7, be positioned at inboard plane, and partial equilibrium counterweight 18,19 be installed on the actuation gear 8, is positioned at outer side plane, partial equilibrium counterweight 14,15 opposed like this, that be positioned at the inboard is held.The gap that exists between adjacent two partial equilibrium counterweights 14,18 and 15,19 enables to avoid the contact of opposing side.Adjacent partial equilibrium counterweight 14,18 and 15,19 has the edge recessed portion (RANDNISCH) of mutual configuration, and each relative partial equilibrium counterweight stretches into wherein.Thereby the external lateral portion counterweight 18,19 that holds inside part counterweight 14,15 has the edge recessed portion that is arranged in its inner side surface, and 14,15 of inside part counterweights are provided with the edge recessed portion at its outer side surface.
Install side by partial equilibrium counterweight 14,15 relative partial equilibrium counterweights 18,19, makes the described counterweight of beginning can extend the zone of opposed gear 8, and kindred circumstances is applicable to the partial equilibrium counterweight 18,19 of gear 7.Thus, the mean radius that partial equilibrium counterweight 14,15,18,19 is calculated institute's foundations increases, and during this radius calculation with a square substitution, so partial equilibrium counterweight 14, thereby 15 quality especially thickness can reduce because it is the linear ratio relation in calculating.
In addition, this kind structural type can be by the quality of removable parts counterweight 14,15,18,19 simply, make it to be easy to special motor on need the inertial force of balance to be complementary.Obviously, when not being separated as if counterweight, its quality also can reduce.In this case, the monolithic counterweight is installed in parallel plane on the axle 5 and 6 as the driving gear drives by being contained in the bearing support outside.
The Equilibrator of pattern provided by the present invention can be contained in the one or both ends of motor.
Shown in the explanation, the present invention is not limited to illustrated embodiment as described above.
