Cross Reference to Related Applications [0001] This Application is a continuation application of co-pending U.S. Application Serial. No. 61/302,598, having Filing Date of February 9,2010, entitled "Torque Tool Having Intensifier and Impact Means", and co-pending U.S. Application Serial. No. 61/430,105, having Filing Date of January 5,2011, entitled "An Apparatus for Tightening and Loosening an Industrial Fastener".
Description of Invention [0002] Power driven torque intensifier tools are known through recent patent application disclosures. In a high speed, low torque first mode at least one intensifier mechanism turns together with the tool housing and the tool output drive. In a low speed, high torque second mode at least one intensifier mechanism turns in one direction while the housing tends to turn in the opposite direction. The housing is stopped from turning by means of a reaction fixture connected with a stationary object.
[0003] EP 2 210 708 A1 is directed to a rotary impact tool includes a drive power source for producing rotational power, a drive shaft driven by the rotational power supplied from the drive power source, an output shaft operatively connected to the drive shaft for receiving the rotational power, and an impact mechanism operatively couplable with the drive shaft.
[0004] EP 2 082 840 A2 discloses a safety torque intensifying tool having a housing, a torque intensifying unit providing at least two modes of operation including a first mode in which the tool operates with a high speed and a low torque and a second mode in which the tool operates with a low speed and a high torque, a grip to be held by a tool operator, an additional element acting as a handle for better gripping in the first mode in which the tool operates with the high speed and low torque and also as a reaction arm to abut against a stationary object to stop the housing from turning in the second mode when the tool operates with the low speed and the high torque, and a switching unit for switching the tool between the first and second modes and configured so that when the operator does not act on the switching unit the tool is in the second mode of operation with the low speed and the high torque, and when the switching unit is switched by the operator while the additional element acts as a handle, the tool is switched to the first mode of operation with the high speed and the low torque, until the operator stops acting on the switching unit and the tool is switched itself back to the second mode of operation.
[0005] US 2010/0011912 A1 shows a hand-held torque power wrench for tightening and loosening fasteners, the torque power tool has a motor, a housing, at least one handle configured to hold the torque power wrench in a position and to pull a trigger with one hand of an operator, and a safety device operatable by the other hand of the operator, so that when it is operated by the other hand of the operator the torque power wrench is functioning to tighten or loosen the fastener, but when the only one hand of the operator is used for holding the torque power wrench in position and pulling the trigger, the torque power wrench is not functioning to tighten or loosen the fastener.
[0006] Other torque power wrenches are shown in US 2007/251359 A1 and EP 2 055 436 A2.
[0007] Often application characteristics adversely affect bolting jobs and include for example corroded, unclean, kinked, debris-laden, burred, galled, irregular, disoriented, misaligned and/or unevenly lubricated stud and nut threads and surfaces. Overcoming adverse bolting application characteristics many times is not feasible in the first mode.
[0008] Most impact mechanisms rely on a mass to be turned at high speed, which creates inertia that ends up into a hammering motion. Various impact mechanisms are known and may include at least one hammer which strikes an anvil while others may operate by vibration caused by interference between the power input and the drive output.
[0009] Some known impact mechanisms are effective in overcoming several adverse bolting application characteristics. The vibration absorbed by the operátorát high torque, however, caused by the high mass of the impact mechanism is harmful. For example, European daily hand to arm vibration exposure action values from power tools is < 2.5 m/s2. Known hand-held, higher torque impact tools exceed this value. The torque output in the first mode therefore is limited to avoid harm to the operator.
[0010] Known low mass, low torque impact mechanisms may avoid vibration exposure harm to the operator and may be ideal for overcoming several adverse bolting application characteristics when running down or running off fasteners. Unfortunately they are ineffective at loosening highly torqued or corroded fasteners that are stuck to their joints and inadequate for higher torque needs which usually require torque precision.
[0011] Use of reaction fixtures at high turning speeds is known to cause injury. Harm commonly befalls operators’ extremities when inadvertently in the wrong place as the reaction fixture can slam against a stationary object. The speed with which these tools operate is therefore limited.
[0012] A dual speed powerdriven torque intensifiertool recently disclosed operates at very high speed to run down or run off a nut without the need for reaction fixtures. This tool spins its housing together with its torque intensifier means, yet the operator must absorb the reaction force when the tool is operated without a reaction fixture. The turning force cannot exceed low torque values. Otherwise the operator’s arm would succumb to the reaction force and twist once the tool applies a torque to overcome adverse bolting application characteristics. In many instances, this tool must react against a stationary object to achieve torque values sufficient to overcome adverse bolting application characteristics, obviously at lower speed.
[0013] Current tooling limitations force operators to use two tools: an impact wrench to run down or off a nut, in the absence of adverse bolting application characteristics, because of high impact force, high rotation speed and low reaction force; and a torque wrench with a reaction fixture to tighten or loosen the nut because of accurate and measurable high torque. Impact wrenches are no longer acceptable at high torque due to inaccuracy and vibration, which is a cause of tennis elbow. And torque wrenches are no longer acceptable at low torque due to low speed.
[0014] The present invention has therefore been devised to address these issues.
[0015] According to a first aspect of the invention we provide an apparatus for reaction-free and reaction-assisted tightening and loosening of an industrial fastener including: a motor to generate a turning force to turn the fastener; a turning force multiplication mechanism for a lower speed/higher torque mode including a plurality of turning force multiplication transmitters; a turning force impaction mechanism for a higher speed/lowertorque mode including a plurality ofturn-ing force impaction transmitters; a housing operatively connected with at least one multiplication transmitter; a reaction mechanism to transfer a reaction force generated on the housing during the lower speed/higher torque mode to a stationary object; wherein during the lower speed/higher torque mode at least two multiplication transmitters rotate relative to the other; at least two impaction transmitters are still; or at least two impaction transmitters and at least one multiplication transmitter rotate together; and wherein during the higher speed/lower torque mode at least two impaction transmitters rattle and either: the housing and the at least two multiplication transmitters are still; the housing and the at least two multiplication transmitters rotate together; or the housing is still and the at least two multiplication transmitters rotate together to achieve a hammering motion from the impaction mechanism.
[0016] Further features of the invention are set out in claims 2 to 25 appended hereto.
[0017] Advantageously, this invention addresses industrial concerns and issues with a tool that: generally falls below recommended vibration exposure action values because the impaction mechanism impacts only in the first mode - at low speed, high torque the impaction mechanism does not impact and therefore does not vibrate; provides a high inertia in the first mode due to a high mass from cooperation between the multiplication and impaction mechanisms, which increases the torque output of the impaction mechanism; runs down and runs off fasteners at high speed without the use of a reaction fixture even when a torque higher than the one absorbable by an operator is required to overcome adverse bolting application characteristics; and loosens highly torqued or corroded fasteners that are stuck to their joints and tightens fasteners to a desired higher and more precise torque with use of a reaction fixture in the second mode.
[0018] The invention may be described by way of example only with reference to the accompanying drawings, of which:

Figure 7 is a side, cross-sectional view, of an embodiment of the present invention.
[0019] Referring to figure 1 by way of example, this shows a perspective view of an embodiment of the present invention as an apparatus 1 for reaction-free and reaction-assisted tightening and loosening of an industrial fastener. Apparatus 1 includes: a drive assembly 100; an intensification assembly 200; a gear/mode shifter assembly 300; a swivel/flip reaction assembly 400; and a safety assembly 500.
[0020] Referring to figure 2 by way of example, this shows a cross-sectional view of an embodiment of the present invention as apparatus 1 A. Apparatus 1A is similar to apparatus 1 as noted by duplication of reference numbers.
[0021] Drive assembly 100 may include a drive housing 101, a drive mechanism 102, a handle 104, and a switching mechanism 105. Drive means 102 generates a turning force to turn the fastener and is shown formed as a motor drive means which includes a motor.
[0022] Drive mechanism 102 may also be formed as a manual drive mechanism, such as a torque wrench. Drive mechanism 102 generates a torque for operation of apparatus 1A. Drive housing 101 is shown as a cylindrical body with handle 104 which is held by an operator and provided with switching mechanism 105forswitching motor 102 on and off.
[0023] Intensification assembly 200 includes a turning force multiplication mechanism 210 substantially for a lower speed/higher torque mode including a plurality of turning force multiplication transmitters. In this embodiment intensification assembly 200 includes three multiplication transmitters 211, 212 and 213. Multiplication transmitters 211,212 and 213 may include gear cages; planetary gears; ring gears; sun gears; wobble gears; cycloidal gears; epicyclic gears; connectors; spacers; shifting rings retaining rings; bushings; bearings; caps; transmission gears; transmission shafts; positioning pins; drive wheels; springs; or any combination thereof. Multiplication transmitters 211,212 and 213 may include other known like components as well.
[0024] It is to be understood that there are various known impaction mechanisms, yet for the most part they consist of an anvil and a turning hammer. The hammer is turned by the motor and the anvil has a turning resistance. This causes a hammering action, which is passed on to the output drive. Intensification assembly 200 includes a turning force impaction mechanism 250 substantially for a higher speed/lower torque mode including a plurality of turning force impaction transmitters. In this embodiment intensification assembly 200 includes two turning force impaction transmitters 251 and 252. Impaction transmitters 251 and 252 may include hammers; anvils; connectors; spacers; shifting rings retaining rings; bushings; bearings; caps; transmission gears; transmission shafts; positioning pins; drive wheels; springs; or any combination thereof. Impaction transmitters 251 and 252 may include other known like components as well.
[0025] Known torque intensifier tools are usually powered by air, electric, hydraulic or piston motors. Often the force output and rotation speed is increased or decreased by means of planetary gears or the like, which become part of the motor. Some known tools temporarily eliminate one or several of the intensifier means to increase the tool motor rotation speed. Other known tools use gear intensification and/or reduction mechanisms as stand alone components or adjacent the motor to increase and/or decrease shaft rotation speed. The present invention may also include such gear intensification and/or reduction mechanisms as stand alone components, as multiplication transmitters and part of multiplication mechanism 210 or as impaction transmitters and part of impaction mechanism 250.
[0026] Intensification assembly 200 includes an intensification housing 220 operatively connected with at least one multiplication transmitter. Apparatus 1A includes a reaction mechanism 401 of reaction assembly 400, which is not fully shown in figures 2-7. Reaction mechanism 401 transfers a reaction force generated on housing 220 during the lower speed/higher torque mode to a stationary object.
[0027] Generally operation of apparatus 1A requires activation or deactivation of impaction mechanism 250 which can be done manually with a switch. Apparatus 1A includes a switching mechanism 230 of intensification assembly 200 shift apparatus 1A between either: multiplication mechanism 210; impaction mechanism 250; part of multiplication mechanism 210 (such as for example one of the plurality of multiplication transmitters); part of impaction mechanism 250 (such as for example one of the plurality of impaction transmitters); or any combination thereof. Switching mechanism 230 may include: shifting collars; shifting rings; ball bearings; bearings; retaining rings; or any combination thereof. Switching mechanism 230 may include other known like components as well.
[0028] In operation the RPMs of apparatus 1A decrease as torque output increases. The activation or deactivation of impaction mechanism 250 alternatively may be automated such that when the RPMs drop below or go beyond a predetermined number, impaction mechanism 250 becomes ineffective or effective. To make the impact mode for industrial fasteners effective it is recommended to take a hammer and anvil device as known, which consists of an impact housing, at least one hammer and an anvil that is usually connected with the tool output drive that turns the fastener.
[0029] In operation the RPMs of apparatus 1A decrease as torque output increases. The activation or deactivation of impaction mechanism 250 alternatively may be automated such that when the RPMs drop below or go beyond a predetermined number, impaction mechanism 250 becomes ineffective or effective. To make the impact mode for industrial fasteners effective it is recommended to take a hammer and anvil device as known, which consists of an impact housing , at least one hammer and an anvil that is usually connected with the tool output drive 270 that turns the fastener.
[0030] Apparatus 1A includes an input shaft 260 to assist in transfer of the turning force from motor 102 to either: multiplication mechanism 210; impaction mechanism 250; part of multiplication mechanism 210 (such as for example one of the plurality of multiplication transmitters 211, 212, 213); part of impaction mechanism 250 (such as for example one of the plurality of impaction transmitters 251,252); or any combination thereof. Apparatus 1A includes an output shaft to assist in transfer of the turning force to the industrial fastener via an output drive 270 from either: multiplication mechanism 210; impaction mechanism 250; part of multiplication mechanism 210 (such as for example one of the plurality of multiplication transmitters 211,212, 213); part of impaction mechanism 250 (such as for example one of the plurality of impaction transmitters 251,252); or any combination thereof.
[0031] Generally apparatus of the present invention make use of an impaction mechanism 250 and a multiplication mechanism 210. In the higher speed/lower torque first mode (see e.g. Figure 1) the impaction mechanism 250 acts to provide a turning force to a hammer. In a lower speed/higher torque second mode (see e.g.
Figure 2) the impaction mechanism 250 acts as an extension to pass on the turning force from one part of the tool to another. The impaction mechanism 250 can be located either close to the tool motor 102 (Figure 7), close to the tool output drive 270 or anywhere in between (Figures 1 to 6).
[0032] In the first mode (e.g. Figure 2), the impaction mechanism 250 always receives a turning force and turns; the housing mayor may not receive a turning force; and the torque output is relatively low, which is why the housing does not need to react. Note that in most embodiments of the present invention, the impaction mechanism 250 is operable only in high speed. This in turn means that at low speed when the torque intensifier mechanism 210 is operable, there is no impact so that there is also no vibration under high torque. Generally, as shown in figure 2, at least two multiplication transmitters 211, 212, 213 are unitary to achieve a hammering motion from the impaction mechanism 250.
[0033] The following discussion relates to figures 2-7. Note that like terms are interchangeable, such as for example: intensifier, multiplier and multiplication; impact and impaction.
[0034] More specifically, in one embodiment of the impact mode, the tool housing and the gear stages 211, 212, 213 stand still while the impact 250 rattles. When the impact mechanism 250 is distant from the motor 102, a shaft from the motor 102 goes through the center of the multipliers 210 to the impact mechanism 250 and from there to the output drive 270. When the impact mechanism 250 is immediately after the motor 102 and in front of the multipliers 210 the motor 102 drives the impact mechanism 250 and a shaft goes from the impact mechanism 250 through the center of the multipliers 210 to the output drive 270 [0035] In another embodiment of the impact mode, the tool housing and the gear stages 211,212, 213 rotate in unison while the impact 250 rattles by locking up the gear stages 211,212, 213. This may be accomplished by connecting either: the sun gear with the ring gear; the sun gear with the gear cage; or the gear cage with the ring gear of a planetary stage. In each case all gear cages and the housing act like one turning extension from the motor 102 to the impact mechanism 250 or from the impact mechanism 250 to the output drive 270 of the tool.
[0036] In another embodiment of the impact mode, the tool housing stands still and the gear cages rotate in unison while the impact 250 rattles by locking up the gear cages with one another. When the impact mechanism 250 is distant from the motor 102 the gear cage(s) act like an extension inside the housing from the motor 102 to the impact mechanism 250. When the impact mechanism 250 is immediately after the motor 102 and in front of the multipliers 210 the gear cages or gear cage act like an extension inside the housing from the impact mechanism 250 to the output drive 270 of the tool.
[0037] Generally during the lower speed/higher torque second mode, as shown in figure 3, at least two multipli cation transmitters 211, 212, 213 rotate relative to the other. In the multiplier mode, the tool housing always rotates opposite to the sun gears and the output shaft of the multipliers 210, which is why the tool housing has to react. When torque is intensified by the multiplier 210, the turning speed is so slow that the impact mechanism 250 is ineffective. If the impact mechanism 250 is located after the multiplier 210 and close to the output drive 270 of the tool, the impact mechanism 250 will not impact if it turns with the last sun gear. If the impact mechanism 250 is located before the multiplier 210 and close to the motor 102, the impact mechanism 250 turns at high speed and needs to be locked.
[0038] In one embodiment where the impact mechanism 250 is distant from the motor 102, the following occurs: the impact mechanism 250 stands still while the multipliers 210 turn; the output shaft from the motor 102 goes to the multiplier 210 for torque multiplication; and the last sun gear extends through the impact mechanism 250 to the output drive 270. When the impact mechanism 250 is immediately after the motor 102 and in front of the multipliers 210, the output shaft from the motor 102 goes through the impact mechanism 250 to the multiplier for torque multiplication and the last sun gear extends to the output drive 270.
[0039] In another embodiment, the impact mechanism 250 turns at the speed of the last sun gear of the force applying multipliers 210. When the impact mechanism 250 is distant from the motor 102, the output shaft from the motor 102 goes to the multiplier for torque multiplication and the last sun gear turns the impact mechanism 250, which turns the output shaft of the tool. When the impact mechanism 250 is immediately after the motor 102 and in front of the multipliers 210, turning the impact mechanism 250 to turn the multipliers 210 would result in impacting, which is to be avoided. On the other hand, the impact mechanism 250 can be locked by locking the hammer with the impact housing , or by locking the hammer with the anvil. The impact mechanism 250 acts as an extension between the motor 102 output drive 270 and the first sun gear of the multiplier.
[0040] The speed of the last sun gear of the multiplier may be high enough to operate the impact mechanism 250. Impaction on the output shaft of the tool is avoidable by locking the hammerwith the impact housing , the ham-merwith the anvil, the impact housing with the tool housing or the hammer with the tool housing .
[0041] In a specific embodiment of the first mode, as for example shown in the top half of figure 6, the multiplication mechanism 210 is close to the motor 102 and before the impaction mechanism 250. The motor 102 bypasses the multiplication mechanism 210 and extends its output force through at least one part of the multiplication mechanism 210 by means of a pin toward the output drive 270. In a specific embodiment of the first mode, as for example shown in the top half offigure 7, the impact mechanism 250 is close to the motor 102 and before the multiplication mechanism 210. The impaction mecha- nism 250 extends its output force through at least one part of the multiplication mechanism 210 by means of a pin toward the output drive 270.
