Abstract
The utility model relates to a novel overrunning clutch, in particular to a novel spring reset overrunning clutch used for a loader, and is characterized in that a reset spring is made by a 65Mn spring steel wire; the diameter of the steel wire is Phi 0.35mm; a finished product spring is formed in hot manner to remove rolling stress and increase pressure resistant strength; a spring seat is made by carbon steel instead of tin bronze; a center oil through hole with the diameter is Phi 1.2 mm is drilled at the bottom of the spring seat; a finished product spring seat is hardened and plated with chrome on the surface or integrally quenched, thereby the novel spring reset overrunning clutch increases abrasive resistance and service life.
Description
Technical field
The utility model relates to a kind of free wheel device, is specifically related to a kind of novel spring homing position type free wheel device that is used for loader.
Background technique
The general spring reset formula free wheel device that adopts in the present homemade loader planetary transmission.The Returnning spring of this clutch adopts carbon steel wire, and spring seat adopts tin bronze, is easy to generate early stage damage and loses efficacy, and can not satisfy the usage requirement of loader.
The purpose of this utility model is to optimize Returnning spring, spring seat and the manufacturing process thereof of clutch, improves reliability and working life, overcomes early stage damage failure phenomenon.
The model utility content
In order to reach Returnning spring, spring seat and the manufacturing process thereof of optimizing clutch, improve reliability and working life, overcome the purpose of early stage damage failure phenomenon, the utility model adopts following scheme:
1, the feature of novel spring homing position type free wheel device is: in the spring reset hole (4) in Returnning spring (1) the one end clutches on ring cam (2) the raceway wall (3), the other end is worn and is loaded onto spring seat (5), roller surface (8) in order to pushing tow roller (6) wedging clutch outer ring gear (7) makes it to turn round together transmitting torque, drives loader and travels and operation.
2, Returnning spring adopts the 65Mn Spring Steel Wire, and steel wire diameter is selected φ 0.35mm for use.The finished product spring carries out heat setting to be handled, and rolls stress with elimination, improves compressive strength.
3, the center oil through that it is φ 1.2mm that spring seat employing carbon steel replacement tin bronze, and present subdrilling is opened a diameter.The finished product spring seat carries out the chrome-faced sclerosis or carries out integral quenching and handle.
Description of drawings
Fig. 1 is the structural representation of the utility model in free wheel device.
1. Returnning springs among the figure, 2. interior ring cam, 3. raceway wall, 4. reset hole, 5. spring seat, 6. ball, 7. outer ring gear, 8. roller surface.
Specific embodiments
Below in conjunction with embodiment the utility model is further described:
With reference to shown in Figure 1: in the spring reset hole (4) in Returnning spring (1) the one end clutches on ring cam (2) the raceway wall (3), the other end is worn and is loaded onto spring seat (5), roller surface (8) in order to pushing tow roller (6) wedging clutch outer ring gear (7) makes it to turn round together transmitting torque, drives loader and travels and operation.
At present, domestic Returnning spring adopts the manufacturing of carbon steel steel wire, and diameter is φ 0.5mm, is easy to generate fatigue failure.The utility model is selected 65Mn high duty alloy steel wire for use, and steel wire diameter is selected φ 0.35mm for use, and carries out heat setting and handle after rolling, and eliminates rolling stress, improves compressive strength and working life.
The prior art spring seat adopts the tin bronze manufacturing, because its ductility is good, it is stuck in reset hole and cause spring reset to lose efficacy to be collided into rivet-like by roller (steel) easily in the work, causes that cltuch slipping can not work.The utility model replaces tin bronze to make spring seat with carbon steel, and carries out the chromium plating sclerosis on its surface or it is carried out integral quenching handle, and has improved the wear-resistant ability of anti-collision, has avoided the generation of spring seat plug-hole phenomenon.Center oil through that diameter is φ 1.2mm of spring seat bottom increase, make working medium and wear particle thing be able to pass through smoothly and flow, help reducing cavity temperature in the spring seat, reduce dirt deposition, thereby reduce the probability that Returnning spring Yin Gaowen generation weakness and dirt cling inefficacy, improve reset reliability and working life.
Claims (3)
1. novel spring homing position type free wheel device, it is characterized in that: in the spring reset hole (4) in Returnning spring (1) the one end clutches on ring cam (2) the raceway wall (3), the other end is worn and is loaded onto spring seat (5), roller surface (8) in order to pushing tow roller (6) wedging clutch outer ring gear (7) makes it to turn round together transmitting torque, drives loader and travels and operation.
2. novel spring homing position type free wheel device according to claim 1 is characterized in that: Returnning spring (1) adopts 65Mn high-quality Spring Steel Wire, and steel wire diameter is φ 0.35mm.
3. novel spring homing position type free wheel device according to claim 1 is characterized in that: spring seat (5) material is a carbon steel, and its surface is carried out the chromium plating sclerosis or carried out integral quenching and handle; The center oil through that it is φ 1.2mm that its subdrilling is opened a diameter.
