Description
Technical field
The present invention relates to gear box arrangement technical fields, determining beam gantry cnc boring and milling machine clearance elimination gear more particularly, to a kind of
Case.
Background technology
Due to mismachining tolerance and installation error etc. between transmission gear between gear-box so that pitch wheel it
Between there are gaps, generate noise during the work time so as to cause gear-box, or even the phenomenon that mutually killing between gear occur,
And during stage-geared, the gap between gear can be progressively amplified, and larger gear clearance can make gear
Engagement generates reverse movement, and equipment damage phenomenon is caused when serious；The gear in said gear case generates gap in order to prevent, leads to
It crosses and spring is installed in gear-box one end and axial thrust is applied to transmission shaft so that transmission shaft axial displacement, to eliminate phase
Gap between the helical gear mutually engaged, while in the one end of transmission shaft far from spring be mutually sequentially connected with motor, motor
Be mounted on gear-box, when need to helical gear carry out it is axial push come when eliminating gap, since installation site and space have
When the one end of relationship or gear-box far from motor of limit is interfered, people, which are merely able to stand, is located at the one of motor in gear-box
Side, staff's hand reach the position of spring, and are difficult that spring is adjusted, and are inconvenient, or gear-box is existed
It is disassembled in equipment, it is time-consuming in this way, reduce working efficiency.
Invention content
The technical problem to be solved by the present invention is to：In order to solve due to the limited relationship of installation site and space or gear
When the one end of case far from motor is interfered, people, which are merely able to stand, is located at the side of motor in gear-box, and staff's hand is enough not
To the position of spring, and it is difficult that spring is adjusted, is inconvenient, or gear-box is disassembled in equipment, this
Sample is time-consuming, the problem of reducing working efficiency, now provides and a kind of determining beam gantry cnc boring and milling machine clearance elimination gear case.
The technical solution adopted by the present invention to solve the technical problems is：It is a kind of to determine beam gantry cnc boring and milling machine clearance elimination gear
Case, including babinet further include the first transmission shaft, the first driving gear and the first driven gear being arranged in babinet, the case
Driving device is provided on body, first driving gear and first driven gear are helical gear, first transmission
The both ends of axis are rotatably arranged on the babinet, and first driven gear is arranged on first transmission shaft, and described first
Driving gear and the first driven gear are intermeshed, and clearance elimination gear are provided on first driving gear, described first actively
Gear and the clearance elimination gear are helical gear in the same direction, and the clearance elimination gear is intermeshed with first driven gear, described
First driving gear and the output end of the driving device are sequentially connected, and one end that the driving device is located on the babinet is set
It is equipped with pressing plate, the pressing plate is located at one end of first transmission shaft, is provided between the pressing plate and first transmission shaft
Plane bearing is provided with spring, is rotated in the babinet and be provided with second driving shaft between the pressing plate and the plane bearing,
First transmission shaft and second driving shaft are arranged in parallel, and the second driving gear, institute are provided on first transmission shaft
It states and is provided with the second driven gear on second driving shaft, second driving gear and second driven gear intermeshing,
Second driving gear and second driven gear are helical gear.Disappeared by first principal and subordinate's gear and clearance elimination gear cooperation
Gap when in addition to being engaged with the first driven gear, while spring is squeezed by pressing plate so that spring applies pretightning force and pushes the
One transmission shaft axial displacement, since the second driving gear and the second driven gear are helical gear, to eliminate second actively
The gap that gear and the second driven gear generate when engaging, the two, which combines, reaches the gap for eliminating generation step by step, final so that pressure
Plate is located at driving device in the same end of babinet, thus staff is facilitated to operate pressing plate and spring, improves work
Make efficiency.
When spring this body length is longer, the meeting of the centre of spring bends, when pressing again to spring, spring
It will bend, so instead so that spring does not have the effect of pressure, spring bends and deviates in order to prevent, into one
Step ground is provided with mandril between the pressing plate and the plane bearing, one end of the mandril, which is supported, to be located on the plane bearing,
The other end of the mandril is contacted with the spring, and locating rod is provided on the mandril, and the spring is set in the positioning
On bar.By the way that spring to be set in the locating rod on mandril, the position-limiting action to spring is played, ensures that spring compression stabilization can
It leans on.
Reliable and stable in order to ensure to press to the first transmission shaft, further, the spring is butterfly spring.Due to spring
For butterfly spring, butterfly spring rigidity is big, and buffering vibration absorption ability is strong, can bear big load with small deformation, be suitable for axial space
It is required that small occasion, while there is butterfly spring variation rigidity characteristic, this spring to have wide range of nonlinear characteristic, use
Long lifespan ensure that reliable and stable to the first transmission shaft pressure.
The beneficial effects of the invention are as follows：The present invention determines beam gantry cnc boring and milling machine clearance elimination gear case when in use, passes through
One principal and subordinate's gear and clearance elimination gear cooperation eliminate gap when being engaged with the first driven gear, while squeezing bullet by pressing plate
Spring so that spring applies pretightning force and pushes the first transmission shaft axial displacement, since the second driving gear and the second driven gear are equal
For helical gear, to the gap for eliminating the second driving gear and when the second driven gear engages generates, the two combine reach by
Grade eliminates the gap generated, finally so that pressing plate is located at driving device in the same end of babinet, thus facilitates staff couple
Pressing plate and spring are operated, and are improved work efficiency, and are avoided due to the limited relationship of installation site and space or gear
When the one end of case far from motor is interfered, people, which are merely able to stand, is located at the side of motor in gear-box, and staff's hand is enough not
To the position of spring, and it is difficult that spring is adjusted, is inconvenient, or gear-box is disassembled in equipment, this
Sample is time-consuming, the problem of reducing working efficiency.
