Abstract
The utility model discloses an improved cooling type gear box which comprises a gear box body, a box cover and a transmission system arranged in the gear box body. An installation port is arranged on the gear box body, the box cover is arranged at the position of the installation port, a cooling liquid chamber is arranged in a chamber at the bottom of the transmission system, the input end of the cooling liquid chamber serves as a cooling liquid inlet, the other end of the cooling liquid chamber serves as a cooling liquid outlet, a composite bush is positioned between the box cover and the installation port, the composite bush 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 into the annular groove, polyurethane sealing glue is filled between the embedded block and the annular groove, an observation window manufactured by bidirectionally stretching polypropylene film is arranged on the box body, the observation window is used for observing the transmission system, and a radiation fin is further fixedly arranged on the inner side of the box body. The improved cooling type gear box is strong in radiation, stable in installation of the box body and the box cover and can solve the problem that the box body moves to generate vibration to enable the box cover to be loose relatively.
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 modified model cooling type gear-box.
For achieving the above object, the technical solution adopted in the utility model is: a kind of modified model 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; Have the sight of making and be used for to observe transmission system by bidirectional stretching polypropylene film on the described casing and show window, described box inside also is installed with radiating fin.
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.
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 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
Shown in Fig. 1,2, the utility model is a kind of modified model cooling type gear-box, comprise gear housing 1, case lid 6 and place the interior transmission system 2 of gear housing, 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 11 and the abaculus of being made by urethane foam 12, be provided with circular groove 13 in the described rubber sleeve 11, described abaculus 12 embeds in the described circular groove 13, also is filled with polyurethane sealant 14 between abaculus 12 and the circular groove 13; Have the sight of making and be used for to observe transmission system by bidirectional stretching polypropylene film on the described casing 1 and show window 10, described box inside also is provided with radiating fin 9 admittedly.
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.
