The utility model discloses a reaming hole bolted connection differential mechanism left side shell and driven gear, the effect of the big moment of torsion of transmission is good.
Description
Technical Field
The utility model belongs to the differential mechanism field, more specifically relates to a coupling mechanism of differential mechanism casing and driven gear.
Background
In the prior art, a differential shell inside a main speed reducer is generally connected with a driven gear through a connecting bolt through a common bolt, and the effect of the common bolt is poor for the main speed reducer with compact structural arrangement and large output torque.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a connecting mechanism of a differential shell and a driven gear,
in order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a coupling mechanism of differential mechanism casing and driven gear, includes differential mechanism left side shell and differential mechanism right side shell, differential mechanism left side shell and differential mechanism right side shell fixed connection still include first reamed hole bolt and driven gear, differential mechanism left side shell and driven gear are through first reamed hole bolt fixed connection.
Further, the first reamed hole bolt is in clearance fit,
furthermore, the differential left shell and the differential right shell are fixedly connected through a second hinged hole bolt.
Further, the second reamed hole bolt is in clearance fit.
Compared with the prior art, the invention has the beneficial effects that:
1. the utility model discloses a first reaming bolted connection differential mechanism left side shell and driven gear, joint strength is high, can transmit big moment of torsion.
2. The connection strength between the differential shell bodies can be enhanced by fixing the differential left shell body and the differential right shell body through the second hinged hole bolts, so that the differential is more compact.
3. The mode of clearance fit can avoid the unable assembly of reamed hole bolt.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;
in the drawings, the components represented by the respective reference numerals are listed below:
1. differential left side shell, 2, differential right side shell, 3, first reamed hole bolt, 4, driven gear, 5, second reamed hole bolt.
Detailed Description
The principles and features of the present invention are described below in conjunction with specific embodiments, which are set forth only for the purposes of explanation and not limitation of the scope of the present invention.
Example 1
As shown in fig. 1, a connecting mechanism of a differential shell and a driven gear comprises a differential left shell 1 and a differential right shell 2, wherein the differential left shell 1 is fixedly connected with the differential right shell 2, the connecting mechanism further comprises a first hinged hole bolt 3 and a driven gear 4, and the differential left shell 1 is fixedly connected with the driven gear 4 through the first hinged hole bolt 3.
Adopt first reamed hole bolt 3 to connect differential mechanism left side shell 1 and driven gear 4, can rely on the shearing strength of reamed hole bolt 3 self to transmit the moment of torsion, joint strength is high, transmits the effectual of big moment of torsion.
First reamed hole bolt 3 is clearance fit, avoids leading to the unable assembly of first reamed hole bolt 3 because of transition fit or interference fit.
Differential left side shell 1 passes through second reamed hole bolt 5 fixed connection with differential right side shell 2, can strengthen the joint strength of differential left side shell 1 and accelerator right side shell 2 like this to make the differential casing compacter.
The second reamed hole bolt 5 is in clearance fit, and the situation that the second reamed hole bolt 5 cannot be assembled due to transition fit or interference fit is avoided.
The first hinged hole bolt 3, the second hinged hole bolt 5 and the circle center of the differential left shell 1 are positioned on the same straight line.
Example 2
The present embodiment differs from embodiment 1 only in the arrangement positions of the first and second hinge- hole bolts 3 and 5.
Specifically, in this embodiment, a plurality of first hinge hole bolts 3 and a plurality of second hinge hole bolts 5 are uniformly distributed on the differential left case 1, and the first hinge hole bolts 3 and the second hinge hole bolts 5 are distributed in a staggered manner; namely, in embodiment 1, a straight line where the first hinge hole bolt 3 and the center of the differential left case 1 are located forms a certain included angle with a straight line where the second hinge hole bolt 5 and the center of the differential left case 1 are located.
The mechanisms, assemblies and components of the present invention that are not described with respect to specific structures are conventional structures that exist in the prior art. Can be purchased directly from the market.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
