Embodiment
The core of the utility model provides a kind of oil sump sealing configuration, and this oil sump sealing configuration makes that the sealing effect between oil sump and the cylinder body is better.Another core of the utility model provides a kind of motor with above-mentioned oil sump sealing configuration.
In order to make those skilled in the art understand the technological scheme of the utility model better, will combine accompanying drawing and specific embodiment that the utility model is done further to specify below.
Shown in Fig. 1-4, the oil sump sealing configuration that the utility model embodiment provides is connected between oil sump 1 and the cylinder body, comprises localization frame and rubber weather strip 3.The sidewall of oil sump 1 can form the top flanged surface 11 that is connected with cylinder body, and this top flanged surface 11 is connected with the cylinder body of motor, can collect and store the lubricant oil that is flowed back to by each rubbing surface of motor, with this in-engine part heat that leaves; The outer surface of rubber weather strip 3 can be the plane; And has the parcel groove 31 that is positioned at horizontal plane on this rubber weather strip 3; After being placed in the top flanged surface 11 of oil sump 1 in this parcel groove 31; Can oil sump 1 and rubber weather strip 3 be fixedly connected on the cylinder body lower end through localization frame, at this moment, rubber weather strip 3 can be realized being tightly connected of oil sump 1 and cylinder body.Above-mentioned localization frame can adopt general metallic material to process integral structure, and its shape is roughly the angular structure that rubber weather strip 3 can be placed in the inboard.
Can know through foregoing description; The content of being introduced in the background technique; The oil sump sealing configuration that the utility model provides is realized being tightly connected of oil sump 1 and cylinder body through rubber weather strip 3; The parcel groove 31 that has on this rubber weather strip 3 is the top flanged surface of oil sump 11 parcels, and then the upper and lower surface of flanged surface 11 all forms elastic force on the top of oil sump 1, enlarges the scope that it can bear pressure with this; Thereby guarantee the elastic deformability of rubber weather strip 3, reach the purpose that improves the sealing effect between oil sump 1 and the cylinder body.
In addition, the rubber weather strip 3 in the above-mentioned oil sump sealing configuration can be oil sump 1 vibration that engine luggine causes comparatively stable cushion effect is provided, thereby plays the effect of noise reduction, and prolongs the working life of oil sump 1 and oil sump sealing configuration.
Further in the technological scheme, the surface that contacts with localization frame on the rubber weather strip 3 that the utility model embodiment provides is a corrugated surface.With respect to plane structure, corrugated surface can make the bigger elastic force of formation between rubber weather strip 3 and the cylinder body, thereby prolongs the effective time of rubber weather strip 3.In like manner, the surface that contacts with cylinder body on can rubber weather strip 3 is set to corrugated surface.
Because the top flanged surface 11 of oil sump 1 is after the flange impact briquetting; Though can carrying out deburring, its end handles; But the edge is still comparatively sharp, and oil sump 1 is being fixed in the process of cylinder body, this part power that can be squeezed; Thereby downward distortion takes place, and this might cause scuffing to rubber weather strip 3.In order to address the above problem, the utility model embodiment is provided with to the surplus groove 311 that extends below in parcel groove 31, and the end of the top flanged surface 11 of oil sump 1 then is positioned at this surplus groove 311.Obviously; This surplus groove 311 provides certain space for the deformation of top flanged surface 11; Thereby the damage that the deformation of avoiding top flanged surface 11 causes rubber weather strip 3, the operating life of assurance rubber weather strip 3 avoids rubber weather strip 3 to damage the generation of the oil leakage phenomenon that is brought.
In the technological scheme further; The localization frame that the utility model embodiment provides specifically comprises first localization frame 21 and second localization frame 22; First localization frame 21 removably is fixedly connected with second localization frame 22, and both end-to-ends, at this moment; The part of rubber weather strip 3 is connected with cylinder body through first localization frame 21, and another part then is connected with cylinder body through second localization frame 22.It is understandable that localization frame is set to split-type structural, be convenient to the processing and the installation of localization frame, help the maintenance of localization frame simultaneously, thereby reduce the maintenance cost of oil sump sealing configuration.
On the basis of such scheme, can first localization frame 21 and/or the manufactured materials of second localization frame 22 be set to aluminium, and adopt the processing method of die cast.Aluminium is a kind of strong but pliable in texture, ductility is better, thermal conductivity is more excellent lightweight material; Its casting manufacturability is better, and surface roughness is lower, does not need secondary machine; Therefore; Adopt the localization frame of aluminum can improve the workability of localization frame, and reduce the weight of this motor, be beneficial to oil sump 1 heat in the lubricant oil in the motor that leaves simultaneously.
In the optimized technical scheme; The lower end of above-mentioned rubber weather strip 3 also can be provided with stretch flange formability 32; This stretch flange formability 32 can wrap up the sidewall of oil sump 1, and when localization frame was fixedly connected with cylinder body, stretch flange formability 32 separated the sidewall of localization frame and oil sump 1; Avoid localization frame to receive after the external force and contact the sidewall that the back scratches oil sump 1 with the sidewall of oil sump 1, thereby guarantee the integrity of oil sump 1.
During practical implementation, localization frame can realize that with being fixedly connected also of cylinder body a plurality of bolts 4 distribute along the top flanged surface 11 of oil sump 1, are the fastening force that provides enough that is connected of oil sump 1 and cylinder body through bolt 4.This scheme adopts bolted means of fixation, is convenient to the dismounting and the maintenance of the component in oil sump 1 and the cylinder body, and the number of bolt 4 is then definite according to the concrete size of motor and operating mode etc.
The motor that the utility model provides comprise oil sump, cylinder body and be arranged at oil sump and cylinder body between the oil sump sealing configuration, this oil sump sealing configuration is the described oil sump sealing configuration of above-mentioned arbitrary scheme.Because above-mentioned oil sump sealing configuration has above-mentioned technique effect, the motor with this oil sump sealing configuration also should have the corresponding techniques effect, no longer describes in detail here.
More than motor and oil sump sealing configuration thereof that the utility model provided have been carried out detailed introduction.Used concrete example among this paper the principle and the mode of execution of the utility model are set forth, above embodiment's explanation just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
