Abstract

The utility model discloses a spindle box body with the functions of noise reduction and shock absorption. Two side surfaces parallel to a transmission shaft of the spindle box body are both in a double-layer wall structure formed by an inner wall and an outer wall, wherein the inner wall is in a fully-closed structure without a square window, the outer wall is connected with the inner wall by a reinforcing plate, the reinforcing plate is provided with casting sand removal square windows with different sizes, and the inner wall and the outer wall best share the same thickness. The spindle box body with the functions of noise reduction and shock absorption has the beneficial effects that noises of a spindle box in a working state can be efficiently reduced and the vibration phenomenon is reduced as the double-layer wall structure is adopted in the spindle box body.

Description

Main spindle box casing with noise reduction shock-absorbing function
Technical field
The utility model main spindle box relates to a kind of main spindle box casing with noise reduction shock-absorbing function, is specially adapted to install on heavy horizontal lathe.
Background technology
In the design process of main spindle box, casing all has only one deck tank wall usually, when the load of casing excessive, when rotating speed is too high, tends to occur excessive noise, even can shake, it is particularly outstanding that this phenomenon seems on heavy horizontal lathe, seriously influenced the normal use of lathe.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of main spindle box casing with noise reduction shock-absorbing function, and is excessive with the noise that solution main spindle box casing occurs in the course of the work, or micro-vibration problem.
The technical solution adopted in the utility model is: the double-wall structures of being made up of inner and outer wall are adopted in main spindle box casing two sides parallel with power transmission shaft, and inwall wherein is the full-closed structure of window not properly.Be connected by gusset between outer wall and the inwall, have the casting sand removal side window that varies in size on the gusset.Inner and outer wall preferably adopts identical thickness.
The beneficial effects of the utility model are: the main spindle box casing can effectively reduce the noise under the main spindle box duty owing to adopted double-wall structure, reduces the generation of oscillation phenomenon.The utility model is under the jurisdiction of the great special problem 2009ZX04002-042 of country.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Number in the figure:
1, inwall 2, outer wall 3, sound insulation chamber 4, gusset 5, main shaft 6, power transmission shaft.
The specific embodiment
As shown in Figure 1, the design's main spindle box casing is made up of following element: inwall 1, outer wall 2, sound insulation chamber 3, gusset 4.
Inwall 1 is the topmost skeleton part of main spindle box, and inwall 1 thickness is even, is the ground floor noise reduction components, simultaneously inner body is played containing, supporting, the effect of sealing, inwall 1 is the evolution window not, and inner driving member is isolated fully in noise district occurred frequently, casing both sides and outside.
Outer wall 2 is last one deck noise reduction components of main spindle box, and thickness is suitable with inwall 1 usually, and is connected by gusset 4 with inwall 1, forms the sound insulation chamber 3 with good result.
Sound insulation chamber 3 is the cavitys with soundproof effect that form between inwall 1 and the outer wall 2, and it is main shaft 5, and the noise that power transmission shaft 6 produces at work drops to bottom line.
Gusset 4 is the excessive parts in centre that connect inwall 1 and outer wall 2, and gusset 4 has the square window that varies in size, and is used to cast sand removal.

Claims (2)

1. main spindle box casing with noise reduction shock-absorbing function, it is characterized in that: the double-wall structure of being made up of inwall (1) and outer wall (2) is adopted in main spindle box casing two sides parallel with power transmission shaft, inwall wherein (1) is a full-closed structure, be connected by gusset (4) between outer wall (2) and the inwall (1), have the casting sand removal side window that varies in size on the gusset (4).
