Abstract
The invention discloses a synchronous belt retarding mechanism for the grinding wheel trimming of a bearing grinder. The synchronous belt retarding mechanism comprises a two-hole oil cylinder, a chain wheel, a chain, an arciform rack and a diamond pen, wherein, the diamond pen is installed on the arciform rack; and two piston rods of the two-hole oil cylinder are connected and installed at two ends of the chain of the chain wheel. The synchronous belt retarding mechanism is characterized in that the chain wheel is installed between the arciform rack and the two-hole oil cylinder; a drive pulley linked with the chain wheel is installed on one side of the chain wheel, and the drive pulley is installed on the side of the chain wheel in a coaxial manner; a timing belt pulley is installed on the arciform rack correspondingly; a synchronous belt is connected between the drive pulley and the timing belt pulley; and the diameter of the timing belt pulley is greater than that of the drive pulley. The synchronous belt retarding mechanism with a simple structure is easy to achieve, and eliminates the polygon effect problem when the chain is trimmed; and in addition, the synchronous belt adopts flexible connection, so that the polygon effect of the chain can be eliminated naturally during the transmission process, and the perfect effect that a finisher rotate at a uniform speed can be achieved.
Description
Technical field
The present invention relates to the bearing grinder technical field, relate in particular to a kind of bearing inner race that is used for and comprise: the synchronous band reducing gear of crushing during orthodrome ditch raceway grindings such as inner ring raceway, spherical roller.
Background technology
In the grinding of bearing inner race raceway, generally all be to adopt crush grinding method, like Fig. 1 and shown in Figure 2; Fig. 1 is a bearing inner race raceway crush grinding sketch map, and Fig. 2 is the driving sketch map of the diamond pen of traditional crushing, is trimmed to emery wheel 1 outer rim the shape that needs; Crush grinding lasso raceway is if the radius R of ditch (rolling) is less, because diamond pen 2 can not rotate a circle; For this reason; All use diplopore oil cylinder 10 to drive generally speaking, diplopore oil cylinder 10 drives the rotation that segmental support 13 is accomplished diamond pen 2 through chain 11 and sprocket wheel 12, and diamond pen 2 is installed on segmental support 13.This cover finishing to the rotation requirement of diamond pen is: low speed, evenly, nothing is creeped, otherwise will directly influence the grinding quality in ditch (rolling) road.
If the radius R in ditch (rolling) road is bigger; During such as grinding self-aligning bearing inner ring raceway or spherical roller, the radius of turn of its diamond pen 2 is compared with the radius of turn of common ball bearing diamond pen, can differ to reach tens times even more; If traditional improvement of breed; At this moment, under the certain situation of the speed of oil cylinder piston, the rotating speed of diamond pen 2 will be original tens times even more.This is unallowed, the reduction of speed of must trying every possible means.Because the diameter of sprocket wheel 12 must be consistent with the pitch-row of diplopore oil cylinder 10, otherwise oblique tension state will appear in piston, causes damage, thus change the diameter of the necessary corresponding change diplopore oil cylinder 10 of diameter of sprocket wheel 12, pretty troublesome! And basic sometimes just the change do not come! So the rotating speed that reduces diamond pen 2 generally has only by reducing the movement velocity of oil cylinder piston.
But if only by reducing the movement velocity of oil cylinder piston, when the pressure of hydraulic system was adjusted to a certain degree, serious low speed jerking motion state will appear in diamond pen 2, when serious even can't revise emery wheel.This is unallowed in the finishing of bearing emery wheel, for this reason, occurs diversified deceleration scheme on the market, but ubiquity complex structure and the shortcoming that can't eliminate the polygon effect of chain when repairing.
Summary of the invention
The object of the present invention is to provide a kind of synchronous band reducing gear that is used for the bearing grinder crushing; It has characteristics simple in structure, that be easy to realize and can eliminate the polygon effect of chain when finishing, to solve the problem that the finishing of prior art middle (center) bearing grinder wheel exists.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of synchronous band reducing gear that is used for the bearing grinder crushing; It comprises diplopore oil cylinder, sprocket wheel, chain, segmental support and is installed in the diamond pen on the segmental support that two piston rods of said diplopore oil cylinder are mounted on the two ends of the chain on the sprocket wheel, wherein; Said sprocket wheel is installed between segmental support and the diplopore oil cylinder; And a side of said sprocket wheel is installed the drive pulley with its interlock, and the one of which side is coaxial is equipped with drive pulley, corresponding to synchronous pulley is installed on the segmental support; Be connected driving-belt between said drive pulley and the synchronous pulley, the diameter of said synchronous pulley is greater than the diameter of drive pulley.
Especially, said sprocket wheel and the coaxial installation of drive pulley.
Especially, said driving-belt is to be with synchronously.
Beneficial effect of the present invention is that the compared with prior art said synchronous band reducing gear that is used for the bearing grinder crushing has the following advantages:
1), simple in structure, utilize original diplopore cylinder structure to realize the deceleration problem easily, and synchronous pulley is standard component, be easy to processing on the market.
2), eliminated the polygon effect problem of chain when finishing, promptly the pitch between the chain makes the problem that the diamond pen instantaneous velocity changes.Because band is to flexibly connect synchronously, in transmission process, eliminate the polygon effect of chain naturally, reached the perfect effect of trimmer uniform rotation.
