The content of the invention
The invention aims to solve the difficulty that crankshaft timing sprocket can not dismantle by interference fit and caused by it is whole The problem that individual bent axle is scrapped, there is provided " a kind of crankshaft sprocket provision for disengagement ", the present apparatus is reasonable in design simply, cost is cheap, Convenient disassembly, easy, time saving and energy saving and less manpower, it is ensured that crankshaft sprocket does not influence bent axle precision and quality when dismantling, and saving is returned Accomplish this, improve economic benefit.
To achieve these goals, the present invention is achieved through the following technical solutions:A kind of crankshaft sprocket dismounting dress Put, main technical scheme is, including pneumatic impact spanner, left support plate 3 and right support plate 5 combine with two semi-circular connecting plates 6 Into dismounting component.
The dismounting component includes the outer-hexagonal bolt 1 that sets gradually from left to right and screw thread is matchedly connected therewith
Left support plate 3, three spiral shells that diameter is adapted therewith are passed through in three unthreaded holes divided equally on the circumference of the left support plate 3 Bar 2, the end of thread of screw rod 2 are directed at connection by matching screwed hole with right support plate 5 and screwed in, six of the right support plate 5 Respectively pass through the six roots of sensation soket head cap screw 4 that diameter is adapted therewith in unthreaded hole, the soket head cap screw 4 is semicircular with two again The corresponding screw-in connection that matches of screwed hole on connecting plate 6.
Further technical scheme is to be provided with what is matched with crankshaft sprocket in the center of two semicircle connecting plates 6
Ladder semicircle orifice 61, make the sprocket wheel on the right of semicircle orifice 61 and 72 tooth right side of sprocket wheel 721 is cylindrical to be engaged and cause chain Gear teeth right side 721 is in contact with the connecting plate left surface 62 of connecting plate 6.
Further technical scheme is that the center of the right support plate 5 is provided with unthreaded hole 51 and causes crankshaft group 7
Left-half smoothly can be passed through with the external diameter of sprocket wheel 72 from hole center.
The invention has the advantages that:
The present apparatus is reasonable in design simply, cost is cheap, convenient disassembly, easy, time saving and energy saving and people from province
Work, it is ensured that crankshaft sprocket dismantles quality and bent axle precision, and efficiency is reprocessed in raising, and cost is reprocessed in saving, improves the performance of enterprises.

Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, a kind of crankshaft sprocket provision for disengagement, including pneumatic impact spanner, left support plate 3 and The dismounting component that right support plate 5 combines with semi-circular connecting plate 6.
The dismounting component includes the outer-hexagonal bolt 1 that sets gradually from left to right and screw thread is matchedly connected therewith
Left support plate 3, three spiral shells that diameter is adapted therewith are passed through in three unthreaded holes divided equally on the circumference of the left support plate 3 Bar 2, the end of thread of screw rod 2 are directed at connection by matching screwed hole with right support plate 5 and screwed in, six of the right support plate 5 Respectively pass through the six roots of sensation soket head cap screw 4 that diameter is adapted therewith in unthreaded hole, the soket head cap screw 4 is semicircular with two again The corresponding screw-in connection that matches of screwed hole on connecting plate 6.
The ladder semicircle orifice 61 to match with crankshaft sprocket is provided with the center of two semicircle connecting plates 6, makes semicircle
Hole 61 with the right side position sprocket wheel of 72 tooth right side of sprocket wheel 721 is cylindrical is engaged, and cause sprocket right side 721 with even The connecting plate left surface 62 of fishplate bar 6 is in contact.
The center of the right support plate 5 be provided with unthreaded hole 51 enable crankshaft group 7 left-half and the external diameter of sprocket wheel 72 Smoothly passed through from hole center.
Specific disassembling section method:
