Description
Technical Field
The utility model relates to a diesel engine part technical field especially relates to a gear of subdivision formula.
Background
At present, an intermediate flange and a crankshaft of a high-power diesel engine on the market are basically designed in an integrated mode, a crankshaft gear is an integrated metal gear, the integrated metal gear is sleeved on the shaft surface of the crankshaft, interference fit is adopted, and the crankshaft drives the crankshaft gear to rotate. However, this construction is problematic in installation and use.
However, in the prior art, the metal gear on the large diesel engine needs to be installed on the crankshaft, the manufacturing precision is high, the deformation in the machining process is difficult to control, and due to the interference fit between the crankshaft gear and the crankshaft, special tools are needed for assembly and disassembly, so that not only is the operation troublesome, but also the crankshaft and the gear are damaged by the assembly and disassembly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a gear of subdivision formula to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a gear of subdivision formula, includes the bent axle, install meshing gear on the bent axle, meshing gear includes subdivision gear and lower subdivision gear, every two draw-in grooves have all been seted up on last subdivision gear and the lower subdivision gear, every the draw-in groove semicircular in shape sets up, every be equipped with the snap ring on the draw-in groove, every two from top to bottom run through connection has the bolt, every threaded connection has the nut on the bolt.
As a further improvement scheme of the technical scheme: two bolts are fixedly connected to the side wall of each lower split gear, and two bolt grooves are formed in the side wall of each upper split gear.
As a further improvement scheme of the technical scheme: and each bolt is sleeved with a rubber ring.
As a further improvement scheme of the technical scheme: the crankshaft is made of hard alloy materials.
Compared with the prior art, the beneficial effects of the utility model are that:
firstly, insert the bolt on the lateral wall of lower subdivision gear in the bolt slot on the lateral wall of upper subdivision gear, can align last subdivision gear and lower subdivision gear and link together, after last subdivision gear and lower subdivision gear were installed on the bent axle, install every two upper and lower snap rings on the draw-in groove again, make the bolt run through two snap rings from top to bottom, tighten the nut again on the bolt, can make two snap rings fix last subdivision gear and lower subdivision gear on the bent axle, the device reasonable in design, the design is ingenious, through faling into last subdivision gear and lower subdivision gear with the meshing gear, greatly reduced the preparation degree of difficulty of meshing gear, be convenient for more control the deformation in the course of working, be convenient for dismouting meshing gear more simultaneously, high practicality.

fig. 2 is a schematic side view of the split gear according to the present invention.
In the figure: 1 meshing gear, 2 bent axles, 3 snap rings, 4 bolts, 5 bolts, 6 nuts, 7 draw-in grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-2, in the embodiment of the present invention, a gear of subdivision formula, including bent axle 2, install meshing gear 1 on bent axle 2, meshing gear 1 includes subdivision gear and lower subdivision gear, has all seted up two draw-in grooves 7 on every last subdivision gear and the lower subdivision gear, and every draw-in groove 7 semicircular in shape sets up, is equipped with snap ring 3 on every draw-in groove 7, and through connection has bolt 4 between every two upper and lower snap ring 3, and threaded connection has nut 6 on every bolt 4.
Referring to fig. 1, two bolts 5 are fixedly connected to the side wall of each lower split gear, two bolt grooves are formed in the side wall of each upper split gear, and the upper split gear and the lower split gear can be connected together in an aligned manner by inserting the bolts 5 on the side wall of the lower split gear into the bolt grooves on the side wall of the upper split gear.
Referring to fig. 1, each bolt 4 is sleeved with a rubber ring, the rubber ring is located between the snap ring 3 and the nut 6, and the nut 6 is more firmly fixed on the bolt 4 by the rubber ring.
Referring to fig. 1, the crankshaft 2 is made of a hard alloy material having excellent red hardness, high hardness, good wear resistance, high elastic modulus, and high compressive strength.
The utility model discloses a theory of operation is:
firstly, insert the bolt 5 on the lower subdivision gear lateral wall in the bolt inslot on the last subdivision gear lateral wall, can align last subdivision gear and lower subdivision gear and link together, after last subdivision gear and lower subdivision gear install on bent axle 2, install snap ring 3 on draw-in groove 7 about per two again, make bolt 4 run through upper and lower two snap rings 3, tighten the nut on bolt 4 again, can make two snap rings 3 fix last subdivision gear and lower subdivision gear on bent axle 2, the device reasonable in design, the design is ingenious, through dividing meshing gear 1 into last subdivision gear and lower subdivision gear, the preparation degree of difficulty of meshing gear 1 has been greatly reduced, be convenient for more control the deformation in the course of working, be convenient for dismouting meshing gear 1 more simultaneously, high practicality.
