Abstract
The utility model discloses an active cooling type gear box comprising a gear box body, a box cover and a transmission system arranged in the gear box body. An installation opening is formed in the gear box body, the box cover is arranged on the installation opening, a cooling liquid cavity is disposed in a cavity at the bottom of the transmission system, the 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. A composite bush is arranged between the box cover and the installation opening, and comprises a rubber sleeve and an embedded block made of polyurethane foaming plastic. An annular groove is arranged in the rubber sleeve, the embedded block is embedded in the annular groove, and polyurethane sealing adhesive is filled between the embedded block and the annular groove. The active cooling type gear box has strong anti-abrasion and anti-corrosion performance so that the gear box can adapt to severe work environment and service life is prolonged.
Description
Technical field
The utility model relates to a kind of gear-box, especially a kind of active cooling type 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 active cooling type gear-box.
For achieving the above object, the technical solution adopted in the utility model is: a kind of active 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;
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.
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.
Description of drawings
Fig. 1 is initiatively cooling type gear-box embodiment's schematic representation of the utility model;
Fig. 2 is the schematic representation of composite bush among Fig. 1.
Embodiment
As shown in Figure 1, 2, the utility model is a kind of active cooling type 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;
Wherein, be provided with composite bush 7 between described case lid 6 and the mount inlet 8, described composite bush 7 comprises rubber sleeve 9 and the abaculus of being made by urethane foam 10, be provided with circular groove 11 in the described rubber sleeve 9, described abaculus 10 embeds in the described circular groove 11, also is filled with polyurethane sealant 12 between abaculus 10 and the circular groove 11.
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.
