Abstract
The utility model discloses a wear resistant cooling type gear case which comprises a gear case body, a case cover and a transmission system which is arranged in the gear case body, wherein an installing opening is formed in the gear case body, the case cover is arranged on the installing opening, a cooling liquid cavity is arranged in a cavity at the bottom of the transmission system, an input end of the cooling liquid cavity is a cooling liquid inlet, the other end of the cooling liquid cavity is a cooling liquid outlet, cooling fins are fixedly arranged at the inner side of the gear case body, an aluminum alloy layer and a ceramic coating are outward sequentially arranged on the surface of the gear case body, the thickness of the ceramic coating is 0.2 millimeter to 0.3 millimeter, a viewing window which is formed by a polypropylene film stretched in two directions and used for observing the transmission system is formed in the gear case body, wherein a composite bush is arranged between the case cover and the installing opening. The wear resistant cooling type gear case has the advantages of being capable of avoiding corrosion in various places and prolonging service life of the gear case.
Description
Technical field
The utility model relates to a kind of gear-box, especially a kind of gear-box that can initiatively cool off.
Background technique
It is one of capital equipment that the lathe of prior art is produced the middle gear case, and can produce a large amount of heat during train wheel operation in the gear-box and cause the rising of gear-box temperature, under the effect that heat is transmitted, to make the component generation thermal distortion that is in contact with it, this thermal distortion will have a strong impact on the equipment machining accuracy in precision machining.
The model utility content
The thermal distortion that heating produces when working in order to reduce gear-box the utility model proposes a kind of wear-resisting type cooling type gear-box.
For achieving the above object, the technical solution adopted in the utility model is: a kind of wear-resisting type cooling type gear-box, comprise gear housing, case lid and place the interior transmission system of gear housing, described gear housing is provided with mount inlet, described case lid is installed in the mount inlet place, be provided with the cooling liquid chamber in the chamber of transmission system bottom, the input end of cooling liquid chamber is cooling liquid inlet, and the other end is cooling liquid outlet; Described box inside is installed with radiating fin, described gear housing surface outwards is provided with aluminium alloy layer, ceramic coating successively, described thickness of ceramic coating reaches 0.2～0.3mm, has the sight of making and be used for to observe transmission system by bidirectional stretching polypropylene film on the described casing and shows window;
Wherein, be provided with composite bush between described case lid and the mount inlet, described composite bush comprises rubber sleeve and the abaculus of being made by urethane foam, is provided with circular groove in the described rubber sleeve, described abaculus embeds in the described circular groove, also is filled with polyurethane sealant between abaculus and the circular groove.
Urethane foam is called hard polyurethane foam again and belongs to hard material.Rubber sleeve is conventional lining, it is flexible structure completely, lack inner skeleton, rubber sleeve under traffic condition or motion (such as the conventional apparatus motion of box house herein, must make casing shake by a small margin, also make case lid shake then) environment is big with the distortion that motion produces, cause sealing effect not good, the long-term use, the distortion that produces will be difficult to recover, and influence using effect and life-span; Composite bush in the utility model adds has abaculus as the hard inner frame, and abaculus embeds in the described circular groove, also be filled with polyurethane sealant (avoiding both gap affects sealing effects) between abaculus and the circular groove, like this when keeping composite bush periphery flexibility, can play the purpose of better restriction composite bush bulk deformation amount, reach better sealing effect, working life is also long like this.
Ceramic coating has stronger wear-resisting and anti-corrosion property energy forming on the aluminium alloy layer after differential arc oxidation method is handled, make casing of the present utility model can adapt to comparatively bad working environment, and long service life.
Having on the casing to be made to see by bidirectional stretching polypropylene film and show window, is whether observe gear operation for the ease of the operator normal, and bidirectional stretching polypropylene film has the characteristic of transparent high temperature resistant simultaneously.
The utility model is when work, machine tool coolant is introduced from the import of cooling liquid chamber, in the cooling liquid chamber, absorb the heat of gearbox drive system, be back to the tank for coolant of lathe from the outlet of cooling liquid chamber, utilize the circulation of machine tool coolant, the heat that produces when taking away gear-box work, the temperature of reduction gear-box, make the component generation thermal distortion that is in contact with it thereby reduce, and then guarantee machine finish; Described box inside is installed with radiating fin simultaneously, the efficiently radiates heat of the casing that can superpose, the radiating effect of increase casing.
