Description
Technical field
This utility model relates to a kind of cylinder, more particularly, it relates to the cylinder of a kind of good heat dissipation effect.
Background technology
Traditional cylinder divides wet type cylinder and dry cylinder.In wet type cylinder outside wet liner then directly with
Engine cooling water contacts, so 2～3 roads being all machined with dress O type rubber seal on all of wet liner cylindrical are recessed
Groove, to prevent from cooling down water entrance crankcase.Wet liner sealing principle is to reach the closeest by rubber ring elasticity interference fit
Envelope.The shortcoming of the wet liner above-mentioned sealing structure of employing is: the rubber magnitude of interference is difficult to accurately control, excessive, is difficult to assemble,
Rubber ring easily cuts off so that it is lose sealing function, too small, easily causes and leaks；The machining accuracy of cylinder jacket and cylinder-bore is wanted
Ask the highest；O-shaped rubber ring is the most aging, just follows the string once aging, then must tear greatly electromotor open, bother very much.
Though therefore O-shaped rubber ring is little, but the biggest to the reliability effect of electromotor.
Through retrieval, the existing technical scheme disclosure improved for the problems referred to above, such as China Patent No.
ZL200920255775.8, authorized announcement date is on August 11st, 2010, and invention and created name is: cylinder, and this application case relates to one
Planting cylinder, including cylinder sleeve and cylinder body, cylinder sleeve outer ring has supporting bable tops, and the support that cylinder body inner ring has support supporting bable tops is convex
Rising, between cylinder sleeve and cylinder body, junction is provided with water shutoff circle, and supporting bable tops is arranged on the middle lower end of cylinder sleeve, and water shutoff circle is fixed on cylinder
Set and the junction of cylinder body upper end, be provided with cylinder sleeve packing ring between supporting bable tops and support protrusion.Owing to supporting in this application case
Table top is arranged at the middle lower end of cylinder sleeve, is not only different from wet liner in prior art and uses O type rubber seal rings for seal, only
By realizing coordinating between supporting bable tops with support protrusion sealing, good sealing effect, and achieve expansion cylinder so that start
Machine can obtain bigger power on the premise of same volume, same weight；But this application case ignores to be positioned in cylinder sleeve and props up
Mounting or dismounting and the problem of heat radiation between part and cylinder body below support table top.
Summary of the invention
1. utility model to solve the technical problem that
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that the cylinder of a kind of good heat dissipation effect, uses this
The technical scheme of utility model, simple in construction, design ingenious, easy accessibility between cylinder jacket and cylinder body, and seal reliable.
2. technical scheme
For reaching above-mentioned purpose, the technical scheme that this utility model provides is:
The cylinder of a kind of good heat dissipation effect of the present utility model, including cylinder jacket and cylinder body, the outer ring of described cylinder jacket
There is supporting bable tops；Described supporting bable tops is arranged at the middle and lower part of cylinder jacket；Described cylinder jacket is positioned on supporting bable tops
Side's part is upper shell, and being positioned at supporting bable tops section below in cylinder jacket is lower shell；The lateral surface processing of described lower shell
Become male and fomale(M&F)；The inner ring of described cylinder body has the support protrusion supporting supporting bable tops.
Further, it is connected by arc structure between the concave surface of described male and fomale(M&F) and convex surface.
Further, it is provided with gasket seal 3 between the described support protrusion supporting supporting bable tops.
Further, the thickness of described upper shell is more than the thickness of lower shell.
3. beneficial effect
The technical scheme using this utility model to provide, compared with existing known technology, has the advantages that
(1) cylinder of a kind of good heat dissipation effect of the present utility model, the outer ring of its cylinder jacket has supporting bable tops, supports platform
Face is arranged at the middle and lower part of cylinder jacket, and when cylinder jacket is pressed into cylinder body, supporting bable tops and support protrusion closely cooperate and can form end
Face seal, seals reliable, and seal pressure is controlled, solves and uses O in prior art between wet liner middle and lower part and cylinder body
RunddichtringO seals the deficiency problem such as aging easily occur, simultaneously under guaranteeing same cylinder body, the external diameter of cylinder jacket can be made to expand
Greatly, when for electromotor, the discharge capacity of electromotor can be increased, thus increase engine horsepower；
(2) cylinder of a kind of good heat dissipation effect of the present utility model, the lateral surface of its lower shell is processed into male and fomale(M&F) so that
Easy accessibility between lower shell and cylinder body, adds the area of dissipation outside cylinder jacket, beneficially cylinder jacket internal heat simultaneously
It is pulled away in time by male and fomale(M&F)；
(3) cylinder of a kind of good heat dissipation effect of the present utility model, is arranged between the support protrusion of its support supporting bable tops
There is gasket seal, be beneficial to guarantee for a long time to seal reliably；
(4) cylinder of a kind of good heat dissipation effect of the present utility model, the thickness of its upper shell is more than the thickness of lower shell, on
Cylinder is thicker to bear bigger lateral pressure, and lower shell is relatively thin to adapt to less lateral pressure, saves material.
