Description
Technical field
Before the present invention relates to a kind of gear part can the assembling in dispatching from the factory, handle, have running-in machine the precision quality-improving of gear part by the processing that sees through quick running-in machine ahead of time.
Background technology
Be generally used in the gear part of mechanical transmission structure, its tooth portion needs numerous and diverse procedure usually, dispatches from the factory immediately after being made as finished product and assembles, and by the engagement of gear teeth portion and tooth portion, reaches the purpose of mechanicalness transmission.
Yet because of the trueness error in the gear manufacturing processing, two mutual meshed gears tooth portions cause easily slightly at the use initial stage and interfere, and this situation makes the loss of transmission of power and easy phenomenon such as generation noise.Therefore, one group of gear teeth transmission mechanism of newly organizing structure needs just can reach optimum state one period running-in period, on the other hand, owing to the abrasion slightly of gear teeth face running-in period, and produce material powder significantly, these material powders very easily are mixed in the lubricating oil, easily cause the bad wearing and tearing of the flank of tooth for a long time and the gear part life-span is greatly reduced, so the common methods that overcomes this problem also only can be early oil change more, remove a little material powders fully as for whether using, be difficult to certainly in fact.
Summary of the invention
Main purpose of the present invention, be to solve the above problems and a kind of gear running-in device of object is provided, before this gear part assembled in dispatching from the factory, the tooth portion processing that sees through together quick running-in machine is ahead of time handled, with the precision of lifting gear part, and then make the new system gear need not to bring into play running-in period its transmission performance and reduction transmission noise.
For achieving the above object, the present invention system comprises:
Two are located at the fixed gear of Y direction fixed position side by side, and this two fixed gears external diameter becomes suitable spacing, and wherein a fixed teeth train is driven rotation by an actuating unit.
One free gear is located at the outside of two gears arranged side by side, and is positioned on the X-axis of the OC mid point phase of two fixed gears arranged side by side quadrature, and it is subjected to a driving mechanism to promote to be the reciprocal shift movement of X-direction.
This driving mechanism comprises one in the slide of the reciprocal shift movement of X-direction and promote a hydraulic cylinder of this slide, is hubbed on the U-shaped seat of slide adjacent fixed gear one side for this free gear, and is provided with two inductive switches in the side of contiguous slide.
Z-direction tool one fore-set between this two fixed gear and free gear articulates a bearing in fore-set is terminal, and is provided with slide in the bottom of fore-set, and the side of contiguous slide is provided with an adjusting device.
Aforementioned two fixed gears and free gear are module (diametral pitch) condition for the treatment of the break-in object that is same as, and two fixed gears and free gear case hardness are all greater than the gear surface hardness for the treatment of the break-in object.

The specific embodiment
See also the example structure of Fig. 1 to Fig. 5, only for the usefulness of explanation, in patent application, be not subjected to the restriction of this kind structure at this.
It is to comprise for a present embodiment:
Have two fixed gears 11,12 of being located at the Y direction fixed position side by side in a board 1 top, this two fixed gears external diameter becomes suitable spacing, and this fixed gear 12 is to be driven rotation by an actuating unit (not shown) in this example.
One free gear 2 is located at the outside of two fixed gears 11,12 arranged side by side, and is positioned on the X-axis of the OC mid point phase of two fixed gears arranged side by side quadrature, and it is subjected to a driving mechanism 3 to promote to be the reciprocal shift movement of X-direction;
This driving mechanism 3 comprises one in the slide 31 of the reciprocal shift movement of X-direction and promote a hydraulic cylinder 32 of this slide, this slide is located on the slide rail 13, be hubbed on the U-shaped seat 33 of slide 4 adjacent fixed gears one side for this free gear 2, and the side in contiguous slide 31 is provided with two inductive switches 34, and mat one control device 4 is awarded and got the shift motion of inductive switch signal with restriction slide 31.
Be provided with a pedestal 5 on the extended position of aforementioned slide rail 13 in this two fixed gear 11,12 and 2 of free gears, tool one fore-set 51 on the pedestal 5 of Z-direction, in the terminal bearing 511 that articulates of fore-set, the side of pedestal 5 is provided with one and adjusts screw group 52, uses and adjusts pedestal in the position of slide rail.
In view of the above, see also Fig. 4 to shown in Figure 5, gear workpiece 8 placed on the fore-set 51, restart driving mechanism 3 and make free gear 2 be the X-direction displacement and towards gear workpiece 8 against; Drive fixed gear 12 when actuating unit makes, make that all 8 engagements form run-in synchronism to fixed gear 11 with the gear workpiece because of tooth portion with free gear 2, utilize hydraulic cylinder 32 to continue to exert pressure, impel to reach quick break-in gear workpiece 8.
Operation principle of the present invention, system is module (diametral pitch) condition that is same as gear workpiece 8 by two fixed gears 11,12 and free gear 2, and, two fixed gears 11,12 and free gear 2 case hardnesses are all carried out break-in work greater than the gear surface hardness for the treatment of the break-in object, the hardness number of general gear workpiece 8 is about HRC57～HRC58, so the hardness number on this two fixed gear and free gear surface is between HRC62～HRC63, cooperate the operating pressure of the hydraulic cylinder 32 of driving mechanism, so can reach the effect of quick break-in work easily.
In addition, the present invention also can further design as Fig. 7, with each fixed gear radially each profile of tooth 121,122 of an end form a taper angles A to other end convergent, and two fixed gear taperings system is reverse each other.When the gear workpiece is meshed with fixed gear, each fixed gear is respectively to the single guiding of gear workpiece tooth portion break-in tapering, so finally cause the profile of tooth 81 of gear workpiece 8 as shown in Figure 8 to lie in axial stage casing, help lowering the transmission noise of gear workpiece to two ends convergent one taper angles A.
Because the gear set specifications size range of various workpiece is extensive, the size range that can insert and put between fixed gear and free gear is for can do suitable reply for this reason, so as shown in Figure 3, the diameter dimension of fixed gear 11,12 is greater than the diameter dimension of free gear 2, and shown in Figure 6 be another example, the diameter dimension of its fixed gear 91,92 is less than the diameter dimension of free gear 93.In addition, the operating pressure of the hydraulic cylinder 32 of driving mechanism system can be set and adjust according to specification of workpieces, and for example this operating pressure scope is between 12kg/cm
2～35kg/cm
2Between.
In addition, the internal gear type workpiece also can be used gear running-in device provided by the present invention and do fast in advance break-in processing processing, as the workpiece 8 of Fig. 9.
In sum, provided by the present invention this gear part is assembled in dispatching from the factory before, fast break-in processing is handled in advance, promoting the precision of gear part, and then makes the new system gear need not can bring into play running-in period its transmission performance and reduces the transmission noise.
