Abstract

The utility model discloses a durable cooling gear case, which comprises a gear case body, a case cover, and a transmission system arranged inside the gear case body, wherein a mounting mouth is formed in the gear case body; the case cover is mounted at the mounting mouth; a coolant liquid cavity is formed inside a cavity at the bottom of the transmission system; the input end of the coolant liquid cavity is the inlet of the coolant liquid, and the other end is the outlet of the coolant liquid; heat dissipating fins are fixedly arranged on the inner sides of the box body; an aluminium alloy layer and a ceramic coating layer are arranged outwards sequentially on the surface of the gear case body; the thickness of the ceramic coating layer reaches 0.2-0.3 mm; and a composite bush is arranged between the case cover and the mounting mouth. The durable cooling gear case provided by the utility model overcomes the defect in the prior art that the transmission system in the gear case body cannot be observed conveniently by operators, and provides a durable cooling gear which can bring convenience to the operators for observing the transmission system, so as to judge whether the operation of the system is normal.

Description

A kind of durable type cooling gear-box

Technical field

The utility model relates to a kind of gear-box, especially a kind of durable type cooling gear-box.

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 durable type cooling gear-box.

For achieving the above object, the technical solution adopted in the utility model is: a kind of durable type cooling 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, and described gear housing surface outwards is provided with aluminium alloy layer, ceramic coating successively, and described thickness of ceramic coating reaches 0.2～0.3mm;

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.

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.

Embodiment

Shown in Fig. 1,2,3, the utility model is a kind of durable type cooling gear-box, comprise gear housing 1, case lid 6 and place transmission system 2 in the gear housing 1, described gear housing 1 is provided with mount inlet 8, described case lid 6 is installed in mount inlet 8 places, be provided with cooling liquid chamber 3 in the chamber of transmission system 2 bottoms, the input end of cooling liquid chamber 3 is cooling liquid inlet 4, and the other end is cooling liquid outlet 5; Described casing 1 inboard is installed with radiating fin 9, and described gear housing 1 surface outwards is provided with aluminium alloy layer 14, ceramic coating 15 successively, and described ceramic coating 15 thickness reach 0.2～0.3mm;

Wherein, be provided with composite bush 7 between described case lid 6 and the mount inlet 8, described composite bush 7 comprises rubber sleeve 10 and the abaculus of being made by urethane foam 11, be provided with circular groove 12 in the described rubber sleeve 10, described abaculus 11 embeds in the described circular groove 12, also is filled with polyurethane sealant 13 between abaculus 11 and the circular groove 12.

Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
