Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of support for van cooler compressor.
Background technology
Van cooler is used to the closed van transporter of transport frozen or fresh-keeping goods, is the fridge equipment of refrigerating unit and the refrigeration special transport automobile in the heat insulation railway carriage or compartment of polyurethane are housed, and is usually used in transport frozen food, dairy products, vegetable and fruit, vaccine medicine etc.The appearance of van cooler and the development freezing and refrigeration of goods in circular flow easily greatly.
Refrigerating machine of refrigerated truck group is for van cooler counter provides endlessly the visual plant of " cold ", can be divided into dependent refrigerating unit and independent cooling unit.General vehicle all adopts external cold, is generally all installed at the forward top of counter, has the profile as air-conditioning, but has stronger refrigerating capacity than the air-conditioning of same volume, and common is exactly refrigerating unit is exactly compressor.
Compressor is all by support installing on van cooler often, in vehicle travel process, needs the stationarity ensureing compressor, under compressor operation pulsation-free precondition, provides stable cryogenic conditions.
The existing supporting structure for installing compressor is more single, and bearing capacity is not high, and period of service is short, needs frequently to change.So the poor stability of compressor in transportation, is unfavorable for the carrying out of refrigeration work.
In sum, for solving existing deficiency on the supporting structure of van cooler compressor, need to design a kind of reasonable in design, good stability and the high support for van cooler compressor of intensity.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of reasonable in design, good stability and the high support for van cooler compressor of intensity.
Object of the present invention realizes by following technical proposal: a kind of support for van cooler compressor, comprising:
Bearing, L-shaped setting for installing compressor;
Support arm, is set to two and two support arms are symmetricly set on bearing both sides, and the curved shape of described support arm arranges and support arm two ends are connected with bearing respectively.
In above-mentioned a kind of support for van cooler compressor, described support arm comprises the head, middle part and afterbody and the three that set gradually and is connected as a single entity, described head, afterbody are connected with bearing respectively, described middle part bends towards internal stent, described head, afterbody to bend and the curvature of head is less than the curvature of afterbody towards bracket outer respectively, and described middle part seamlessly transits respectively to head, afterbody.
In above-mentioned a kind of support for van cooler compressor, be also symmetrically arranged with sub-arm in bearing both sides, one end and the bearing of sub-arm are connected, and the middle part of the other end and support arm is connected.
In above-mentioned a kind of support for van cooler compressor, the back plate that described bearing comprises horizontally disposed connecting panel and vertically arranges, connecting panel being also installed with the adapter plate for installing compressor, offering some mounting holes at adapter plate.
In above-mentioned a kind of support for van cooler compressor, described sub-arm and connecting panel are connected, and described head and connecting panel are connected, and described afterbody and back plate are connected, and head, afterbody arc transition is extremely corresponding respectively connecting panel, back plate.
In above-mentioned a kind of support for van cooler compressor, described bearing is made up of ferrormanganese, described ferrormanganese is become to be grouped into by following parts by weight: iron 100-300 part, manganese 200-500 part, silicon 50-80 part, carbon 20-30 part, titanium carbide 20-30 part, molybdenum 10-20 part, scandium 5-10 part, lanthanum 5-10 part.
Iron powder and manganese powder are the main materials of ferrormanganese, both need to sieve, guarantee that iron powder is roughly consistent with the granularity of manganese powder, when ferrous powder granules size is between 200-400 order and when manganese powder grain size is between 300-400 order, iron powder and manganese powder can form austenite when vacuum-sintering, and carbon is coated on iron atom, the contact of starvation and iron atom, when ferrous powder granules is excessive, the alloy that cannot sinter alloy or sintering with manganese powder into very easily ruptures; When ferrous powder granules is too small, carbon will be difficult to be coated on iron atom, and iron atom is very easily oxidized or corrode; Equally when manganese powder particle is excessive or too small time, the alloy that cannot sinter alloy or sintering with iron powder into very easily ruptures.
Fault in ferrormanganese is formed by the slippage on slipping area of Shockley imperfect dislocation, and ε martensite is also with fault forming core, by imperfect dislocation expansion and grow up, from crystal structure, theoretical according to dislocation motion, ferromanganese ratio is in this application best.
In above-mentioned a kind of support for van cooler compressor, the preparation method of described ferrormanganese material is:
Iron powder is sieved, ferrous powder granules size is between 200-400 order, manganese powder is sieved, make manganese powder grain size be between 300-400 order;
