Abstract
The utility model discloses an active cooling type gear box with low noise. The active cooling type gear box with the low noise comprises a gear box body, a box cover, and a drive system which is arranged in the gear box body. A mounting mouth is formed in the gear box body. The box cover is arranged at the position of the mounting mouth. A cooling fluid chamber is arranged in a cavity at the bottom of the drive system. An input end of the cooling fluid chamber is a cooling fluid inlet, and the other end of the cooling fluid chamber is a cooling fluid outlet. Composite lining is arranged between the box cover and the mounting mouth. A view window which is made of biaxially oriented polypropylene film and used for observing the drive system is formed in the gear box body. An acoustic panel is mounted on the inner wall of the gear box body. The active cooling type gear box with the low noise has the advantages that noise in gear box body running process can be reduced, and the drive system inside the gear box body can be observed.
Description
Technical field
The utility model relates to a kind of gear-box, especially a kind of active cooling type gear-box of low noise.
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, the component generation thermal distortion that is in contact with it will be made, this thermal distortion will have a strong impact on the equipment machining accuracy in precision machining, after the transmission system in the gear housing started simultaneously, the sound of operation was excessive, befouling environment, certain stimulation that brings of also giving operator's health.
The model utility content
Can to reduce noise in order reducing when gear-box is worked, to the utility model proposes a kind of active cooling type gear-box of low noise.
For achieving the above object, the technical solution adopted in the utility model is: a kind of active cooling type gear-box of low noise, 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, on the described cabinet wall acoustic board is installed.
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.
Acoustic board belongs to prior art, is to process according to the Principles of Acoustics exquisiteness, is made up of facing, core and sound-absorbing mat.Wooden acoustic board divides two kinds of the wooden acoustic boards of groove wood acoustic board and hole.At cabinet wall acoustic board is installed, is had noise reduction, the noise that can as far as possible reduce in the utility model gear-box diffuses to the external world.
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 the active cooling type gear-box embodiment's of the utility model low noise schematic representation;
Fig. 2 is the schematic representation of composite bush among Fig. 1.
Embodiment
Shown in Fig. 1,2, a kind of active cooling type gear-box of low noise, 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, on described casing 1 inwall acoustic board 9 is installed.
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.
