Abstract
The utility model provides a combined engine snubber suitable for front power takeoff, comprising a snubber and a crankshaft belt pulley, wherein the snubber and the crankshaft belt pulley are independent structures; a first group of corresponding connection holes are arranged on the snubber and the crankshaft belt pulley; through a first group of bolts, the crankshaft belt pulley is connected with the snubber; a second group of connection holes are arranged on the crankshaft belt pulley and the snubber; the second group of connection holes are used as connection holes of a front takeoff adapter; a group of countersinks are arranged on the front power takeoff adapter; the positions of the countersinks are corresponding to the second group of connection holes on the crankshaft belt pulley and the snubber; through a second group of bolts, the front power takeoff adapter is connected with the crankshaft belt pulley and the snubber; the first and second groups of connection holes are arranged at intervals; and the groove top and groove bottom of a belt groove on the crankshaft transit by a filleted corner with the R being 0.5mm. The combined engine snubber suitable for front power takeoff is good in structural strength, high in production efficiency and high in material utilization rate and has the effects of increasing the harshness and containment with belts and reducing the risks of belt dropping and tearing.
Description
Technical field
The utility model belongs to technical field of engines, is specifically related to a kind of composite engine vibration damper that is suitable for preceding power taking.
Background technique
At present, engine snubber and crank pulley adopt integrated design more, and power taking is not used before not considering simultaneously; Unusual difficulty when causing that power taking is used before follow-up the installing additional, integrated molding production difficulty is big, and quality conformance is relatively poor; Need change assembly during local damage, cause user's maintenance cost high.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, processing and composite engine vibration damper easy to assembly, that reduce power taking before being used for of user's maintenance cost.
The technological scheme of the utility model: the composite engine vibration damper of power taking comprises vibration damper, crank pulley before a kind of being suitable for of the utility model; Its vibration damper and crank pulley are absolute construction separately; First group of corresponding attachment hole arranged on vibration damper and the crank pulley, crank pulley is connected with vibration damper through first group of bolt; Also be provided with second group of attachment hole on crank pulley and the vibration damper; Second group of attachment hole is as the attachment hole of preceding power taking ABAP Adapter; On the preceding power taking ABAP Adapter one group of counterbore is arranged; The position of counterbore is corresponding with second group of attachment hole on crank pulley and the vibration damper, by second group of bolt preceding power taking ABAP Adapter is connected with vibration damper with crank pulley.
Described first group of attachment hole and second group of attachment hole separation.
The round-corner transition that belt grooves groove top on the described crank pulley and bottom land adopt R=0.5mm.
The technique effect of the utility model: the utility model first Application is on engine snubber, and the combined type design is produced in batches simple, and quality conformance is good, and the commutativity of single part has reduced user's maintenance cost.Crank pulley adopts the processing of cold-stamped spinning process, and belt grooves groove top and bottom land adopt the round-corner transition of R=0.5mm, and structural strength is good, manufacturing efficiency and stock utilization height; The flute profile of crank pulley is a fillet, increases the smoothness and the containment of itself and belt, the risk of reduce belt dropping, tearing.

Embodiment
Fig. 1 is the general structure schematic representation of the utility model:
The composite engine vibration damper that is suitable for preceding power taking of the utility model; Comprise vibration damper 1, crank pulley 2; Its vibration damper 1 is an absolute construction separately with crank pulley 2; Corresponding first group of attachment hole 1b, 2b are arranged on vibration damper 1 and the crank pulley 2, crank pulley 2 is connected with vibration damper 1 through first group of bolt 4; Also be provided with second group of attachment hole 1a, 2a on crank pulley 2 and the vibration damper 1; Second group of attachment hole is as the attachment hole of preceding power taking ABAP Adapter 3; On the preceding power taking ABAP Adapter 3 one group of counterbore 3a is arranged; The position of counterbore 3a and crank pulley 2 is corresponding with second group of attachment hole 1a, 2a on the vibration damper 1, by second group of bolt 5 preceding power taking ABAP Adapter 3 is connected with vibration damper 1 with crank pulley 2.
Fig. 2 is an attachment hole distribution schematic diagram on the crank pulley 2: described first group of attachment hole 2b and second group of attachment hole 2a separation.On the vibration damper 1 attachment hole distribute with crank pulley 2 on identical.
Fig. 3 is the crank pulley structural representation of the utility model: the round-corner transition that belt grooves groove top on the described crank pulley 2 and bottom land adopt R=0.5mm.
General first group of attachment hole has four, and bolt 4 connects both through the attachment hole 2b of crank pulley 2, the attachment hole 1b of vibration damper 1; Six of second group of attachment holes, bolt 5 is connected with crank pulley 2 preceding power taking ABAP Adapter 3 through the counterbore 3a of preceding power taking ABAP Adapter 3, the attachment hole 2a of crank pulley 2, the attachment hole 1a of vibration damper 1 with vibration damper 1.
When before the needs during power taking, the utility model is connected as a single entity crank pulley 2, vibration damper 1 and bent axle through bolt 4; Through bolt 5 preceding power taking ABAP Adapter 3, crank pulley 2, vibration damper 1 and bent axle are connected as a single entity again.During power taking, only need crank pulley 2, vibration damper 1 and bent axle are connected as a single entity before do not need through bolt 4.When single part is damaged, only need to change the single part that damages.
