Abstract
The utility model discloses a high-precision keyless coupling feeding box comprising a feeding box body and a gear system, wherein the gear system is arranged in the feeding box body and mainly comprises a gear shaft and a gear; and the coupling between the gear and the gear shaft is expanding sleeve coupling or splined coupling. The high-precision keyless coupling feeding box is reliable and smooth in gear ratio, ensures accurate feeding amount, and can improve the transmission performance of the feeding box.
Description
Technical field
The utility model relates to a kind of feed box, for being mainly used in CNC planer type milling machine, numerical control gantry planer, numerical control horizontal lathe, high accuracy equipment such as NC vertical lathe and floor type boring and milling machine.
Background technology
The axle of known feed box and with the connecting of this upper member, mainly be to cooperate the shaft shoulder, axle journal, and be aided with connectors such as key, back-up ring and sleeve and be connected, wherein key is the connector that is used for transmitting moment of torsion, is a kind of driving coupling part that is most widely used on axle.But binding is connected to its intrinsic defective, at first is to be subject to quality of fit and assembly precision, and the fastness of key connecting is bad, and local stress is excessive when transmitting moment of torsion; Binding is connected to sideshake, though key connecting generally adopts the mode of interference fit, sideshake is inevitable, influences transmission accuracy, may also can cause moving of a upper member.And back-up ring and sleeve belong to align member, and assembly precision requirement itself is just very low, are easy to produce become flexible, and cause its service life on the low side.
Summary of the invention
Therefore, the utility model provides a kind of high-precision keyless feed box at the defective of present key connecting on feed box is used, and gearratio is reliable, steady, guarantees that the amount of feeding is accurate, improves the transmission performance of feed box.
The technical solution adopted in the utility model is:
The keyless feed box of the utility model high accuracy comprises the feeding casing and is arranged on the gear train that is mainly formed by gear shaft and gear in this casing, and connecting between described gear and the gear shaft that is installed on is swollen cover connection or splined.
According to the keyless feed box of the high accuracy of technical solutions of the utility model, connect from spline earlier and talk about, adopt spline to replace key and carry out connecting of gear shaft and gear, be key more than the spline name, but its be actually be different from key and member that can not individualism, it depends on gear shaft, process on the tangible gear shaft, circumferential load uniformity is all arranged, and transmission capacity improves greatly, and gearratio is reliable.Spline can be eliminated the influence of sideshake to machining accuracy, has improved the performance of transmission further, and has guaranteed the accurate of feeding, stable drive.In addition, spline is smaller to the negative effect of axle, can not produce stress and concentrate, and has guaranteed the service life of axle.
It then is a kind of seamless connectivity that swollen cover connects, and it is connected in the gearratio reliability, the stationarity aspect is more reliable than splined, and swollen cover connects reliable more than common key connecting.
Description of drawings
Further set forth architectural feature of the present utility model below in conjunction with Figure of description, wherein:
Fig. 1 is the structural representation according to the keyless feed box of high accuracy of technical solutions of the utility model.
Among the figure: 1, feeding casing, 2, gear shaft, 3, axle sleeve, 4, bearing, 5, ring flange, 6, gear, 7, the feeding case lid, 8, end ring, 9, pressing plate, 10, ringfeder.
The specific embodiment
With reference to explanation accompanying drawing 1, according to the technical solution of the utility model, the keyless feed box of a kind of high accuracy comprises feeding casing 1 and is arranged on the gear train that is mainly formed by gear shaft 2 and gear 6 in this casing, and connecting between described gear and the gear shaft that is installed on is swollen cover connection.
The keyless feed box of high accuracy is the critical component that kinetic energy is provided for lathe, also can do the usefulness of other accurate mechanical equipments, mining and engineering construction.Main by feeding casing 1, feeding case lid 7, be installed on the ring flange 5 on the bearing saddle bore, and the gear shaft 2, the gear 5 that are used for transmission are used for bearing, the bearing baffle 8 of support teeth wheel shaft, and ringfeder 10, the pressing plate 9 of output shaft is installed.
Traditional transmission case body often needs key is fixed in order to guarantee the precision of transmission, has influenced the efficient of dismounting, safeguards inconvenience.This programme then fundamentally addresses this problem.
