Abstract
The utility model discloses a power terminal pad of a fuel injection pump of an engine. The power terminal pad comprises a first through groove, a second through groove, a third through groove and a fourth through groove. The power terminal pad is characterized in that the middle of the pad is provided with a circular hole, and the first through groove, the second through groove, the third through groove and the fourth through groove are formed in the quadrilateral axes of the circular hole, the first through groove and the second through groove are formed in the same axis as the center of the circular hole, the third through groove and the fourth through groove are formed in the same axis as the center of the circular hole, the axis of the first through groove and the second through groove is mutually vertical and crossed to the axis of the third through groove and the fourth through groove, and the openings of an upper hole and a lower hole of the circular hole are provided with chamfer angles. The first through groove, the second through groove, and the third through groove and the fourth through groove are rectangular and are formed in a pad body between the circular hole and the side wall of the outer ring of the pad, and the pad is made of textolite. The pad has the advantages of little transmitting torque, simple structure, easiness in installation and low cost. The pad has the certain vibration damping performance, and therefore the pad is rich in tenacity and elasticity due to the usage of the textolite.
Description
Technical field
The utility model relates to engine fuel oil system field, particularly a kind of injection pump of engine power tie-plate.
Background technique
Conventionally, Injection Pump is directly installed to by several construction bolts in the gear chamber of motor, on the power input shaft of Injection Pump, actuation gear is installed.But some motor, due to the reason of complete machine layout, as air compressor and the shared power input shaft of Injection Pump, maybe need to consider Injection Pump position, so that maintenance, like this, oil injection pump driving gear axle cannot directly be passed to Injection Pump, need by passing to Injection Pump after middle component (as air compressor, bearing support), this kind of drive, needs power tie-plate transferring power again.Such transmission of power has many modes, installs and adjusts complexity, and some is rigidly connected and only plays the effect of transmitting torque, there is no damping effect, more or less Injection Pump is had to certain damage.For mini engine or low-powered engine, the required driving torque of Injection Pump is little, although the scheme transmitting torque that model utility provides is limited, under the prerequisite that meets transmission of power, the most simple, also has damping effect.
Summary of the invention
The technical problem that the utility model solves be to provide a kind of transmitting torque little, simple in structure, install easy, with low cost and have an Injection Pump tie-plate of certain damping property.
Technical solution of the present utility model is such, a kind of injection pump of engine power tie-plate, comprise the first groove, the second groove, the 3rd groove, four-way groove, it is characterized in that there is disk (5) at disk (5) center, on (5) four jiaos of shaft axiss of disk, there is the first groove (1), the second groove (2), the 3rd groove (3), four-way groove (4), the first groove (1), the center of circle of the second groove (2) and circular hole (6) is on same shaft axis, the 3rd groove (3), the center of circle of four-way groove (4) and circular hole (6) is on same shaft axis, its first groove (1), the second groove (2) and the 3rd groove (3), the mutual square crossing of shaft axis of four-way groove (4), the upper and lower nose end mouth of circular hole (6) has chamfering (7).
The first groove (1), the second groove (2), the 3rd groove (3), four-way groove (4) are rectangular groove, open at circular hole (6) to the disk body between the wall of disk (5) limit, outer ring.
Disk (5) is manufactured with masonite.
The beneficial effects of the utility model are: tie-plate is made discoid, opened four rectangular slots of uniform distribution on tie-plate, two grooves are connected with Injection Pump, and the part (as transmission shaft etc.) that another two grooves give over to power intake connects.The thickness of tie-plate is determined according to the torque of transmitting, and generally needs 12-20mm left and right, and transmitting torque is not more than 30N.m.Materials'use take into account toughness and flexible masonite, with low cost, damping property is high, easy to install.
Accompanying drawing explanation
Fig. 1 is that a kind of injection pump of engine power tie-plate master of the present utility model looks schematic diagram.
Fig. 2 is a kind of injection pump of engine power tie-plate vertical view cutaway drawing of the present utility model.
reference character: the first groove (1), the second groove (2), the 3rd groove (3), four-way groove (4), disk (5), circular hole (6), chamfering (7).
Embodiment
Below in conjunction with accompanying drawing, the embodiment of model utility is described in detail, but is to be understood that the protection domain of model utility is not subject to the restriction of embodiment.
Disclosed is above only a specific embodiment of the present utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
Claims (3)
1. an injection pump of engine power tie-plate, comprise the first groove, the second groove, the 3rd groove, four-way groove, it is characterized in that there is circular hole (6) at disk (5) center, upwards there is the first groove (1) in (6) four jiaos of shaft axis footpaths of circular hole, the second groove (2), the 3rd groove (3), four-way groove (4), the first groove (1), the center of circle of the second groove (2) and circular hole (6) is on same shaft axis, the 3rd groove (3), the center of circle of four-way groove (4) and circular hole (6) is on same shaft axis, its first groove (1), the second groove (2) and the 3rd groove (3), the mutual square crossing of shaft axis of four-way groove (4), the upper and lower nose end mouth of circular hole (6) has chamfering (7).
2. a kind of injection pump of engine power tie-plate according to claim 1, it is characterized in that the first groove (1), the second groove (2), the 3rd groove (3), four-way groove (4) are rectangular groove, open at circular hole (6) to the disk body between the wall of disk (5) limit, outer ring.
3. a kind of injection pump of engine power tie-plate according to claim 1, is characterized in that disk (5) manufactures with masonite.
