Abstract
The boom hoisting of a kind of gravity-center adjustable, is used for assisting differential assembly to be assembled to speed reducer assembly.The groove opened on mandrel coordinates with suspension hook, and mandrel is connected with suspension hook, and mandrel and differential assembly inner hole, the crotch of suspension hook coordinates with differential assembly step, and crotch is hooked on differential assembly step, and suspension ring are connected with suspension hook；Mandrel can rotate around bearing pin one, and after differential assembly is sling, suspension hook can catch on differential assembly, and mandrel and differential assembly are in level, are not affected by suspension hook angle；Have multiple for loss of weight and the hole that adjusts suspension ring position on suspension hook, by adjusting the position of suspension ring between hole, differential assembly center of gravity can be found, make differential assembly be in level when slinging.This utility model solve the lifting of existing differential assembly suspender exist the risk that comes off and cannot the problem of level lifting, do not affect the installation of bearing outer ring, and be avoided that security incident, it is simple to assembling, simple in construction, easy to use, low cost of manufacture.
Description
Technical field
This utility model relates to auto parts and components mounting technology field, specifically one and is used for assisting differential assembly to assemble
Instrument on speed reducer assembly.
Background technology
During the assembling of vehicle bridge speed reducer assembly, need differential assembly is lifted into the enterprising luggage of speed reducer assembly
Join, but differential assembly structure is special, do not have preferable Heave Here, to hang the big of differential assembly with hinge type suspender all the time
Wheel both sides, at Heave Here, step is little, there is the potential safety hazard come off, simultaneously because be not the center of gravity of differential assembly at bull wheel,
It cannot be guaranteed that differential assembly is in level after lifting, add assembly difficulty.
Summary of the invention
For overcoming the deficiency of existing suspender, goal of the invention of the present utility model is to provide rising of a kind of gravity-center adjustable to lift
Put, with solve original differential assembly suspender dangerous and can not level lifting differential assembly problem.
For achieving the above object, the groove that mandrel of the present utility model is opened coordinates with suspension hook, and mandrel passes through with suspension hook
Bearing pin one, split pin one connect, mandrel and differential assembly inner hole, and the crotch of suspension hook coordinates with differential assembly step,
Crotch is hooked on differential assembly step；Suspension ring are connected with suspension hook.
Described mandrel can rotate around bearing pin one, and after differential assembly is sling, suspension hook can catch on differential assembly, mandrel and difference
Speed device assembly is in level, is not affected by suspension hook angle.
Have multiple for loss of weight and the hole that adjusts suspension ring position on described suspension hook, described Kong Weiwu to ten, by
Adjust the position of suspension ring between hole, differential assembly center of gravity can be found, make differential assembly be in level, suspension ring when slinging
It is connected with suspension hook by bearing pin two and split pin two.
This utility model is first to be enclosed within bearing inner race by bearing outer ring, then by mandrel and differential assembly inner hole,
Suspension hook coordinates with differential assembly step, and finds the center of gravity of differential assembly (first to look for the when of debugging by the hole on suspension hook
Good), lift by crane differential assembly, the crotch of suspension hook hook up to differential assembly step, it is ensured that lifts by crane safe and reliable, simultaneously mandrel
Level it is under gravity with differential assembly, then after the bearing outer ring of opposite side is set on bearing inner race,
Differential assembly is lifted on speed reducer assembly assembling.
This utility model compared with prior art, solve the lifting of existing differential assembly suspender exist the risk that comes off and
Cannot the problem of level lifting, though with differential assembly endoporus as Heave Here, but the installation affecting bearing outer ring, and
It is avoided that security incident, it is simple to assembling, simple in construction, easy to use, low cost of manufacture.Can be widely applied to the difference of all size
The lifting of speed device assembly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is application sketch of the present utility model.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the groove 7 that mandrel 4 of the present utility model is opened coordinates with suspension hook 1, mandrel 4 and suspension hook 1
Being connected by bearing pin 1, split pin 1, mandrel 4 can rotate around bearing pin 1, can guarantee that differential assembly 11, after slinging, hangs
Hook 1 can catch on differential assembly 11, and mandrel 4 the same with differential assembly 11 can be in level, not by suspension hook 1 angle simultaneously
Impact；Mandrel 4 coordinates with the endoporus 8 of differential assembly 11, and the crotch 5 of suspension hook 1 coordinates with differential assembly 11 step 10,
During lifting differential assembly 11, crotch 5 is hooked on differential assembly 11 step 10；Suspension ring 6 are by bearing pin 2 13, split pin 2 14
Be connected with suspension hook 1, suspension hook 1 have eight holes 12, for loss of weight, simultaneously as the irregular structure of differential assembly 11 and
Center of gravity is not placed in the middle, by adjusting the position of suspension ring 6 between these eight holes 12, can find the center of gravity of differential assembly 11.
During lifting, first bearing outer ring 9 is enclosed within bearing inner race, then mandrel 4 is joined with differential assembly endoporus 8
Closing, suspension hook 1 coordinates with differential assembly step 10, and is found the center of gravity (debugging of differential assembly 11 by the hole 12 on suspension hook 1
When first find), lift by crane differential assembly 11, the crotch 5 of suspension hook 1 hook up to the step 10 of differential assembly 11, it is ensured that
Lifting by crane safe and reliable, mandrel 4 and differential assembly 11 are in level, under gravity then by opposite side simultaneously
After bearing outer ring is set on bearing inner race, differential assembly 11 is lifted on speed reducer assembly assembling.
