Abstract
The utility model provides a kind of loader free wheel device, large ring gear is connected on the gear shaft of shaftgear by bearing, gear shaft between large ring gear and shaftgear is installed with pawl base, circumferentially pin shaft hole is provided with along pawl base side roof part, be movably connected on pawl base by bearing pin in the middle part of ratchet, large ring gear inner ring is evenly equipped with ratchet, ratchet front end one direction is stuck in ratchet teeth groove, it is characterized in that, described ratchet rear end is provided with spring groove, spring groove is built with spring, the spring the other end is welded on pawl base lateral margin by pressing plate, pressing plate side has reseting groove.The utility model structure is simple, be convenient to install, eliminate the drawback of prior art, make ratchet front end precompression more lastingly balanced, brake safe is reliable, can greatly reduce wear, improve driving component operating conditions, extend the working life of ratchet and large ring gear, reduce maintenance load and spare parts consumption, reduce operating cost, improve loader operating rate.
Description
Technical field
The utility model belongs to gearing field, particularly relates to a kind of free wheel device being specifically designed to loader.
Background technique
What loader adopted is free wheel device.In recent years, more advanced is the free wheel device taking ratchet, ratchet to engage mode of braking, its large ring gear is connected on the gear shaft of shaftgear by bearing, gear shaft between large ring gear and shaftgear is installed with pawl base, circumferentially be provided with pin shaft hole along pawl base side roof part, be movably connected on pawl base by bearing pin in the middle part of ratchet, large ring gear inner ring is evenly equipped with ratchet, ratchet front end one direction is stuck in ratchet teeth groove, to realize the braking of gear shaft.The precompression of ratchet is realized by the adsorption force of magnet, is namely inlaid with a block permanent magnet in ratchet rear end, also fixes a block permanent magnet simultaneously, rely on the attraction force between two block permanent magnets to be pressed against on ratchet ratchet front end on the corresponding position of pawl base side.But this mode also exists following defect: one is the easy demagnetization of permanent magnet, affects magnetic, when the distance after demagnetization or between two block permanent magnets is slightly far away, just there will be the phenomenon that suction is not gone up or suction is inadequate, very easily cause and brake ineffective or beat tooth problem; Two is permanent magnets is inlay into by manually breaking, and because permanent magnet is frangible, is easily smashed by permanent magnet breaking in process, adds the consumption of permanent magnet; Three is that part near permanent magnet is magnetized, and very easily adsorbs dregs, increases the wearing and tearing between driving component, directly affect the working life of driving component, not only increases expense expenditure and maintenance load, and has a strong impact on the operating rate of loader.
Summary of the invention
It is simple that the utility model aims to provide a kind of structure, is convenient to install, and ratchet front end precompression can be kept balanced lasting, and brake safe is reliable, and effectively extends the loader free wheel device of clutch life cycle.
For this reason, the solution that the utility model is taked is:
A kind of loader free wheel device, large ring gear is connected on the gear shaft of shaftgear by bearing, gear shaft between large ring gear and shaftgear is installed with pawl base, circumferentially pin shaft hole is provided with along pawl base side roof part, be movably connected on pawl base by bearing pin in the middle part of ratchet, large ring gear inner ring is evenly equipped with ratchet, ratchet front end one direction is stuck in ratchet teeth groove, it is characterized in that, described ratchet rear end is provided with spring groove, spring groove is built with spring, and the spring the other end is welded on pawl base lateral margin by pressing plate, and pressing plate side has reseting groove.
Compared with the prior art, the beneficial effects of the utility model are:
Owing to changing ratchet front end precompression into rely on Compress Spring spring-back force by relying on the suction of two block permanent magnets, eliminate the drawback of prior art, make ratchet front end precompression more lastingly balanced, brake safe is reliable, greatly can reduce wear, improve driving component operating conditions, extend the working life of ratchet and large ring gear, reduce maintenance load and spare parts consumption, reduce operating cost, improve loader operating rate.And the utility model structure is simple, is convenient to installation and maintenance.
Accompanying drawing explanation
Fig. 1 is loader free wheel device sectional drawing;
Fig. 2 is ratchet, ratchet snap-in structure schematic diagram.
In figure: shaftgear 1, connecting bolt 2, pawl base 3, ratchet 4, ratchet 5, bearing pin 6, large ring gear 7, bearing 8, gear shaft 9, reseting groove 10, spring 11, pressing plate 12.
Embodiment
From accompanying drawing, loader free wheel device, comprises shaftgear 1, connecting bolt 2, pawl base 3, ratchet 4, bearing pin 6, large ring gear 7, bearing 8, spring 11 and pressing plate 12.Shaftgear 1 right-hand member is provided with one section of gear shaft 9, and large ring gear 7 inner ring is evenly equipped with ratchet 5.
Large ring gear 7 is connected on the gear shaft 9 of shaftgear 1 by bearing 8, and the gear shaft 9 between large ring gear 7 and shaftgear 1 is installed with pawl base 3, and pawl base 3 connecting bolt is fixed on shaftgear 1.8 pin shaft holes are circumferentially equidistantly provided with along pawl base 3 side roof part, be movably connected on the pin shaft hole position of pawl base 3 by bearing pin 6 in the middle part of ratchet 4, the inner ring of large ring gear 7 is evenly equipped with saw tooth-shaped ratchet 5, and the front end one direction of ratchet 4 is stuck in the teeth groove of ratchet 5.The utility model is processed with a spring groove in the rear end of ratchet 4, and spring 11 one end is embedded in spring groove, and the other end is fixed on pressing plate 12, and pressing plate 12 is welded on the lateral margin of pawl base 3.For ensureing that ratchet 4 can return smoothly, therefore also have a slot formula reseting groove 10 on the side of each pressing plate 12.
