Abstract

PURPOSE:To reduce the number of stages and production cost of a reduction gear mechanism for improving transmission efficiency by providing a helical gear or the like for a first stage of a reduction gear and a spiral bevel gear for a second stage to constitute a drive device from 2 stage reduction gear mechanism. CONSTITUTION:A helical gear 11 is provided for a first stage reduction gear mechanism and a spiral gear 12 for a second stage one. And a drive force of a DC motor 4 is transmitted through a coupling 5 to the helical gear 11 and from the helical gear 11 to the spiral bevel gear 12 by which is driven wheels 3 coupled with a spline shaft 10 through the spline shaft 10. Thus, since the reduction gear mechanism which had heretofore 3 stages gets to have 2 stages, the transmission efficiency of the drive force can be improved while the number of gears and the production cost can be reduced. Also since a spur gear is not used, gear noise is reduced.

【発明の詳細な説明】 本発明は、リーチフォークリフトの駆動装置の改良に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a drive device for a reach forklift.

従来のリーチフォークリフトの駆動装置の一例を２図面

る。A gear case 1 is supported by a driving wheel bracket 2 so as to be freely pivotable around a vertical axis. A wheel 3 is held at the lower end of the gear case 1 so as to be rotatable around a horizontal axis, and a DC motor 4 is fixed to the upper part of the driving wheel bracket 2. The driving force of this DC motor 4 is transmitted to a spiral bevel gear 6 via a coupling 5, and then transmitted to a spur gear 9 via an idle gear 8 by a spur gear 7 coaxial therewith, and then further transmitted to a spur gear 9 via an idle gear 8. 9 drives the wheel 3 connected thereto via a spline shaft 10. This allows the reach forklift to run and stop.

、歯車のかみ合い個所が。As mentioned above, the conventional drive device includes a spiral bevel gear 6, an idle gear 8. The wheels 3 were driven by a three-stage reduction mechanism using spur gears 9. Therefore, the meshing points of the gears.

あった。Spiral bevel gear 6, spur gear 7 and idle gear 8.
and in three locations between the idle gear 8 and the spur gear 9,
There was a drawback that the transmission efficiency of driving force was reduced. Furthermore, since the number of gears is large, manufacturing costs are high, and since many spur gears are used, the gear noise is loud.

本発明は、上記のような欠点を除去するため。The present invention aims to eliminate the above-mentioned drawbacks.

ォークリフトの駆動装置を提供するものでおる。This is a reach forklift drive device with a two-stage deceleration mechanism, which aims to improve transmission efficiency by reducing the number of stages in the deceleration mechanism, reduce production costs, and reduce gear noise. This is what we provide.

以下１本発明を第２図に示す一実施例について図面に基

9 and a spiral bevel gear 12 as a second stage reduction mechanism. The driving force of the DC motor 4 is transmitted to a helical gear 11 via a coupling 5, and then transmitted from the helical gear 11 to a spiral bevel gear 12, which is connected to a wheel connected thereto via a spline shaft 10. Drive 3.

用するので歯（３） 単音が減少するという極めて優れた効果がある。As described above, the reach forklift drive device according to the present invention has a two-stage deceleration mechanism instead of the conventional three-stage deceleration mechanism, which improves the driving force transmission efficiency and reduces the number of gears. Costs fall. Furthermore, since only helical gears and spiral bevel gears are used without using spur gears, there is an extremely excellent effect of reducing the number of single teeth (3).

なお、上記実施例では第１段の減速機構としてヘリカル
ギヤを装備した場合について述べたが。Incidentally, in the above embodiment, a case has been described in which a helical gear is provided as the first stage speed reduction mechanism.

では、上記実施例と同様の効果を奏することができる。It is also possible to equip a spur gear instead of a helical gear. In this case, although it is not as good as the helical gear in terms of reducing gear noise, it can achieve the same effect as the above embodiment in that the reduction mechanism has two stages instead of three.
