Fan-shaped cam gear
Technical field
The oil pump of using when the utility model relates to a kind of production and processing.
Background technology
Now use the worm-drive pay-off, transmission efficiency is low, weares and teares more serious, and heating is serious, and especially this defective of process at high velocity ram machine is more obvious.Concrete shortcoming is as follows:
1, processed complex, cost is high, maintainability is poor
2, feeding is unstable, and shake is large, efficient is low
3, feeding time is long, and transmission efficiency is low
When 4, cooperating mould to use, poor stability easily breaks mould
The utility model content
The utility model provides a kind of fan-shaped cam gear, and it is simple in structure, compact, design is convenient, can realize any desired movement of driven member, and product type can arbitrarily be regulated.
A kind of fan-shaped cam gear, comprise the feeding firm banking, be installed in the feeding correcting plate on described feeding firm banking both sides, two rollers are installed on the feedblock, be provided with in the middle of described two rollers and rotate fan-shaped cam, described fan-shaped cam drives described two rollers as circular motion and rotates, and drives simultaneously described feedblock and make to come and go rectilinear motion in the zone of described feeding firm banking and the restriction of feeding correcting plate.
Described feedblock is arranged on the centre of two blocks of feeding correcting plates, and the regional movement according to feeding correcting plate limits increases stability, and described feedblock one end also is connected with the feeding guide contiguous block.
The advantage that the utlity model has is as follows:
1, guarantees feeding transmission process stability
2, the summit can be used at a high speed without impact, and accelerating curve is continuous
3, product type can be compatible
4, reduced cost of manufacture, maintenanceability improves, and processing is simple
Description of drawings
Fig. 1 is the fan-shaped cam gear structural representation that the utility model provides.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of fan-shaped cam gear that the utility model embodiment provides, comprise feeding firm banking 1, be installed in the feeding correcting plate 2 on described feeding firm banking both sides, two rollers 4 are installed on the feedblock 3, be provided with in the middle of described two rollers and rotate fan-shaped cam 5, described fan-shaped cam is made circular motion, driving described two rollers rotates, drive simultaneously described feedblock and in the zone of described feeding firm banking and the restriction of feeding correcting plate, make to come and go rectilinear motion, the i.e. direction of arrow among the figure.
Described feedblock is arranged on the centre of two blocks of feeding correcting plates, and the regional movement according to two blocks of feeding correcting plates limit increases stability, and described feedblock one end also is connected with feeding guide contiguous block 6.
The utility model provides a kind of fan-shaped cam gear, and it is simple in structure, compact, design is convenient, can realize any desired movement of driven member, and product type can arbitrarily be regulated.
