Abstract
The utility model discloses a wear resistant type actively cooling gear case which comprises a gear case body and a transmission system which is arranged in the gear case body. 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, and 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, and 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. Due to the fact that the cooling fins are fixedly arranged at the inner side of the gear case body, effective cooling of the gear case body can be repeatedly accumulated in an overlying mode, and the cooling effect of the gear case body can be increased.
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 and initiatively cools off gear-box.
For achieving the above object, the technical solution adopted in the utility model is: a kind of wear-resisting type initiatively cools off gear-box, comprise gear housing and place the interior transmission system of gear housing, in the chamber of transmission system bottom, be provided with the cooling liquid chamber, 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.
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.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local enlarged diagram of A among Fig. 1.
Embodiment
As shown in Figure 1, 2, the utility model is that a kind of wear-resisting type initiatively cools off gear-box, comprise gear housing 1 and place the interior transmission system 2 of gear housing, in the chamber of transmission system 2 bottoms, be provided with cooling liquid chamber 3, the input end of cooling liquid chamber 3 is cooling liquid inlet 4, and the other end is cooling liquid outlet 5; Described box inside is installed with radiating fin 6, described gear housing 1 surface outwards is provided with aluminium alloy layer 8, ceramic coating 9 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 7.
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.
