Abstract
A kind of bent axle and gear connection structure, it includes bent axle and gear, is arranged on bent axle by interference connected mode after the heated insulation of gear, and the heating-up temperature of gear is 180 220 DEG C, and soaking time is 50 70 minutes, and bent axle is H7/u6 with the tolerance fit of gear.By adopting the above-described technical solution, compared with prior art, the utility model takes small volume；Transmitting torque reliability, uniform force.
Description
Technical field
The utility model belongs to geological prospecting apparatus field, it particularly relates to a kind of bent axle and gear connection structure.
Background technology
In geological drilling industry, piston high-density pump is essential equipment.With advances in technology, slush pump
To miniaturization, in order to airborne supporting.In the power power end structure of slush pump, power passes to bent axle by gear
And convert rotational motion into linear reciprocating motion.In view of easy to process, gear is parts processing with bent axle, is then reconnected
To together.
As shown in figure 1, this is a kind of bent axle and gear connection structure the most frequently used on existing slush pump, including：Gear
1st, bent axle 2, bolt 3 and spring washer 4；Multiple connects bent axle 1 and gear 2 along the uniform bolt 3 of circumference of gear and spring washer 4
Pick up and, power passes to bent axle 2 through gear 1.This kind of structure is disadvantageous in that：1st, the necessary headspace of bolt connection,
Diameter dimension is big, causes the sufficiently bulky of whole power end；2nd, when slush pump overloads, because bolt strained uneven grade is former
Cause, is easily caused bolt fracture.
The content of the invention
One of the purpose of this utility model is the above-mentioned deficiency for overcoming prior art, and provides a kind of bent axle and be connected with gear
Structure.
Realizing the technical scheme of the utility model above-mentioned purpose is：A kind of bent axle and gear connection structure, including bent axle and
Gear, is arranged on bent axle after the heated insulation of gear by interference connected mode.
The further technical scheme of the utility model is：The heating-up temperature of gear is 180-220 DEG C, and soaking time is 50-
70 minutes.
Further technical scheme is the utility model：Bent axle is H7/u6 with the tolerance fit of gear.
The two of the purpose of this utility model are the above-mentioned deficiencies for overcoming prior art, and provide a kind of bent axle and be connected with gear
Method.
Realizing the technical scheme of the utility model above-mentioned purpose is：A kind of bent axle and gear connection method, its step include：
Step one：Heating：Gear is heated to temperature for 180-220 DEG C；
Step 2：Insulation：The gear that will have been heated in step one does isothermal holding, and soaking time is 50-70 minutes；
Step 3：Install：The gear that isothermal holding will have been done in step 2 is mounted on bent axle；
Step 4：Cooling：The bent axle that will be assembled and gear air cooling.
The further technical scheme of the utility model is：The heating-up temperature of gear be 180-220 DEG C, preferably 185-215 DEG C,
More preferably 190-210 DEG C, further preferably 195-205 DEG C；Soaking time is 50-70 minutes, more preferably preferably 52-68 minutes, 55-65
Minute, further preferably 58-62 minutes.
The further technical scheme of the utility model is：Bent axle is H7/u6 with the tolerance fit of gear.
By adopting the above-described technical solution, compared with prior art, the utility model takes small volume；Transmitting torque
It is reliable, uniform force.
Brief description of the drawings
Fig. 1 is the structural representation of existing bent axle and gear connection structure；
Fig. 2 is structural representation of the present utility model.
Specific embodiment
Embodiment
As shown in Fig. 2 a kind of bent axle and gear connection structure, including bent axle 1 and gear 2, after the heated insulation of gear 2
It is arranged on bent axle 1 by interference connected mode.
The utility model is not limited to above-mentioned preferred embodiment, and anyone should be learnt in enlightenment of the present utility model
Under the structure change made, it is every have with the utility model it is same or similar as technical scheme, belong to this practicality newly
The protection domain of type.
Claims (3)
