Abstract
A turbocharger bearing antiskid structure belongs to the technical field of engine parts and comprises an aluminum alloy seat and a deep groove ball bearing. One to three annular grooves are arranged on the outer circumference of the deep groove ball bearing, expansion compensation nylon arranged inside the annular grooves is fixedly connected with the annular grooves, the widths of the annular grooves are 2-3mm of the axial height of the deep groove ball bearing, and the depths of the annular grooves range from 0.5 millimeter to 1.5 millimeters. Compared with the prior art, the turbocharger bearing antiskid structure has the advantages that the deep groove ball bearing cannot slip relatively to a bearing block due to temperature rise of a system, the nylon can constantly guarantee combination of the deep groove ball bearing with the aluminum alloy seat to maintain an internal backlash after assembly, and the service life of a turbocharger can be prolonged from sixty thousand kilometers to 150 thousand kilometers.
Description
Technical field
The utility model relates to a kind of turbosupercharger, and particularly a kind of turbo-charger bearing anti-skid structure belongs to the engine components technical field.
Background technique
The effect of turbosupercharger is to provide powerful air pressure to motor to automobile when just starting, thereby increases the power output of motor, so automobile can start fast.Bearing is installed on this turbocharger rotor exactly, bears radial load, also controls the axial displacement of rotor simultaneously.
Well-known motor does work at combustor inner cylinder by fuel and produces power, because the fuel quantity of input is subjected to sucking air quantitative limitation in the cylinder, therefore the power that motor produced also can be restricted, if the ride quality of motor has been in the optimum state, increasing output power again can only enter cylinder and increase fuel quantity by the compression more air, thereby improves the burning capacity for work.Therefore under present technical specifications, turbosupercharger is the only mechanical device that can make motor increase output power under the constant situation of working efficiency.Our usual said turbo charging installation is exactly a kind of air compressor in fact, increase the air inflow of motor by pressurized air, in general, turbosupercharging all is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the interior turbine of turbine chamber, turbine drives coaxial impeller again, the air that the impeller force feed is sent here by the air-strainer pipeline makes it supercharging and enters cylinder.When engine speed speeds, the waste gas velocity of discharge and secondary speed also speed synchronously, impeller just compresses more air and enters cylinder, the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and adjust the rotating speed of motor just can increase the output power of motor.But after having passed through pressurized machine, the temperature of system will raise greatly, so this just proposes very high requirement to bearing, otherwise the life-span of system will reduce greatly.
As shown in Figure 1, 2, in actual use, because the turbo charger speed height, temperature rise is fast, and the aluminum alloy bearing seat is easy to be heated, thereby the size in seat hole becomes big, and the linear expansion coeffcient of bearing is less relatively, and bearing and aluminum alloy bearing seat are just skidded easily, causes bearing early failue, just very fast loss of function of turbosupercharger causes automobile to start fast.
The model utility content
The purpose of this utility model is in the above-mentioned prior art, bearing and aluminum alloy bearing seat skid easily, cause bearing early failue, turbosupercharger is the defective of very fast loss of function just, a kind of turbo-charger bearing anti-skid structure is provided, can not skid with bearing support, can guarantee combining of bearing and aluminum alloy seat all the time, thereby prolong the life-span that turbine increases depressor greatly because of the temperature rise of system.
The technological scheme taked of the utility model is to achieve these goals: a kind of turbo-charger bearing anti-skid structure, comprise aluminum alloy seat and deep groove ball bearing, described deep groove ball bearing external diameter is provided with 1 to 3 road circular groove, expansion compensation type nylon is arranged in the circular groove, and expansion compensation type nylon and circular groove are for fixedlying connected.
Described circular groove is 2 roads.
Described expansion compensation type nylon is that injection moulding is connected with circular groove.
The width of described circular groove is the 2-3mm of deep groove ball bearing axial height.
The width of described circular groove is 2.5mm.
The degree of depth of described circular groove is 0.5-1.5mm.
The degree of depth of described circular groove is 1mm.
In actual use, turbine increases actuator temperature and raises, because nylon has good thermal expansion coefficient, so in use, nylon ring can guarantee combining of deep groove ball bearing and aluminum alloy seat all the time, also can make the inside play bearing is kept original assembling after temperature raises after simultaneously.Thereby prolong the life-span that turbine increases depressor.
Compared with prior art, the beneficial effects of the utility model are:
(1) deep groove ball bearing can not skid with bearing support because of the temperature rise of system, and nylon ring can guarantee combining of deep groove ball bearing and aluminum alloy seat all the time, thereby prolongs the life-span that turbine increases depressor, is increased to 150,000 kilometers from 60,000 kilometers.
(2) can make inside play deep groove ball bearing is kept original assembling after temperature raises after, have high temperature resistantly, high-revolving feature can guarantee that turbine increases the depressor proper functioning.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Shown in Fig. 3,4, a kind of turbo-charger bearing anti-skid structure comprises aluminum alloy seat 1 and deep groove ball bearing 2, and deep groove ball bearing 2 external diameters are provided with 2 road circular grooves 21, expansion compensation type nylon 22 is arranged in the circular groove 21, and expansion compensation type nylon 22 is connected for injection moulding with circular groove 21.The width of circular groove 21 is 2.5mm.The degree of depth of circular groove is 1mm.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
